Motion to revoke pre-trial detention – when does it make sense?

Pre-trial detention is one of the most serious moments in a criminal case. For the suspect, it means isolation, lack of normal contact with family, interruption of work, disconnection from everyday life, and immense stress. For loved ones, it is often a sudden situation: someone has been detained, then brought to court, and after the hearing it turns out they will not return home.

At such a moment, the most important question arises: is there anything else that can be done?

The answer is: yes, in many cases further actions can be taken. One of them is a motion to revoke pre-trial detention or to replace detention with a milder preventive measure. However, this is not a letter that should be written on the basis of “please release because the family misses them.” Such a motion must refer to specific grounds for detention, evidence, the suspect’s situation, and whether further isolation is truly necessary.

Pre-trial detention is intended to secure the proper course of criminal proceedings. It should not be a punishment before a verdict. This is very important because a person in pre-trial detention is still not legally convicted. They still benefit from the presumption of innocence, and the defence can take actions to demonstrate that detention is unnecessary, too harsh, or can be replaced by another measure.

If the case concerns a person who has been detained and there is a risk of further isolation, it is also worth knowing the rules described on the page police detention. If the court has already ordered detention, it becomes crucial to prepare actions regarding pre-trial detention and the entire strategy within criminal defence.

What is pre-trial detention?

Pre-trial detention is a preventive measure used in criminal proceedings. It is the harshest measure because it involves depriving the suspect or accused of liberty before the final conclusion of the case.

It is not applied by the police. In the preparatory proceedings, pre-trial detention is applied by the court at the prosecutor’s request. This means that the police may detain someone, the prosecutor may file a motion for detention, but the final decision is made by the court.

The basic provisions concerning preventive measures, including pre-trial detention, are found in the Code of Criminal Procedure. The current consolidated text of the 2026 Act is available in the Internet Legal Acts System of the Sejm.

Pre-trial detention may be applied only when certain conditions are met. Mere suspicion that someone committed a crime is not enough. Authorities must demonstrate that there are grounds for applying the preventive measure and that milder measures are insufficient.

In practice, the court may consider, among others:

• whether there is a high probability of committing a crime
• whether there is a risk of flight
• whether there is a risk of hiding
• whether there is a risk of influencing witnesses
• whether there is a risk of coordinating versions with other persons
• whether there is a risk of destroying evidence
• whether the charge is serious
• whether a severe penalty is threatened
• whether a milder measure can be applied
• what the suspect’s personal situation is

Detention should be an exceptional measure. In practice, however, for the family of the detained person, the most important thing is not the theory but what can be done after the decision is issued.

Pre-trial detention and detention – what is the difference?

Detention and pre-trial detention are not the same.

Detention is a short-term deprivation of liberty. It may occur, for example, when the police detain a person suspected of committing a crime, perform actions, transport them to a unit, interrogate them, or bring them to the prosecutor’s office. Detention is usually the first stage.

Pre-trial detention is a further and much more serious measure. It is decided by the court. If applied, the person is placed in a remand centre for a specified period. This can be several weeks, several months, and in more complex cases, detention may be extended.

Simply put:

• detention is a short procedure at the beginning of the case
• pre-trial detention is a court decision on isolation for the duration of the proceedings
• a detained person may be released after the actions are performed
• a person in pre-trial detention is placed in a remand centre
• detention does not always end with charges
• pre-trial detention usually means the case is already at a serious stage

If the family learns that a loved one has been detained, it is necessary to act quickly. If later information appears about a detention hearing or the application of detention, the case requires immediate analysis.

Does pre-trial detention mean guilt?

No. Pre-trial detention does not mean that the person is guilty. It is not a verdict. It is not a punishment. It does not determine the end of the case.

It is a preventive measure intended to secure the proceedings. The court may find that at a given stage there are grounds for isolating the suspect, but this does not mean a final conviction.

This distinction is very important. Families often hear: "since the court ordered detention, the case is probably lost." This is not true. After detention is applied, actions can still be taken: analyzing the justification, filing a complaint, preparing a motion to revoke or change the detention, collecting documents, indicating new circumstances, presenting arguments against further isolation.

Of course, pre-trial detention means the situation is serious. It should not be underestimated. But one must not assume that nothing can be done anymore.

When can one consider a motion to revoke pre-trial detention?

A motion to revoke pre-trial detention may make sense when there are arguments showing that further detention is unnecessary. Sometimes it is because there were no grounds for detention from the beginning. Sometimes the grounds existed but later ceased. Sometimes new circumstances have arisen. Sometimes it can be shown that milder measures suffice.

In practice, the motion may be considered when:

• the risk of tampering has ceased
• key witnesses have already been interviewed
• the most important evidence has been secured
• the suspect has a permanent place of residence
• the suspect has family and work in Poland
• the health condition argues against further isolation
• police supervision can be applied
• a financial surety can be applied
• a prohibition on contact with certain persons can be applied
• a ban on leaving the country can be applied
• the charges do not justify further isolation
• the evidentiary material has weakened
• the proceedings are not conducted efficiently
• the detention has lasted a long time and requires reassessment

It is not enough to simply state that the suspect wants to return home. This is understandable but usually insufficient for the court. It is necessary to show why detention is no longer necessary from the perspective of the proceedings.

Revocation vs. modification of pre-trial detention

In practice, it is worth distinguishing two things: revocation of detention and modification of detention to another preventive measure.

Revocation means that the court ceases to apply detention. The suspect is released without replacing detention with another measure or with much lighter obligations, depending on the procedural situation.

Modification means that detention is replaced by a milder measure. This may be, for example:

• police supervision
• financial surety
• ban on leaving the country
• passport retention
• prohibition of contact with certain persons
• restraining order
• order to behave in a specified manner
• suspension from duties, if the case concerns this

In many cases, a request to change detention to a milder measure may be more realistic. The court may have doubts about completely abandoning preventive measures but may consider further isolation too excessive.

Therefore, a good motion often does not limit itself to the sentence: "I request revocation of detention." It may also contain an alternative request, for example, a plea to change detention to police supervision and financial surety.

What is the difference between a motion to revoke detention and a complaint?

This is a very important difference.

A complaint is filed against the decision to apply or extend pre-trial detention. This means the party challenges a specific court decision. The deadline must be observed because the complaint has a set time limit for filing.

A motion to revoke or modify pre-trial detention may be filed later, when arguments arise that detention should no longer be applied. Such a motion may be based on new circumstances or on the fact that the previous grounds for detention have lost their relevance.

Simply put:

• a complaint challenges a specific detention decision
• a motion for revocation or modification concerns the continued application of detention
• a complaint is time-bound
• a motion may be renewed if new arguments arise
• a complaint is often filed promptly after the court's decision
• a motion may be part of a broader defence strategy

This does not mean that one excludes the other. In many cases, a complaint is filed first, and later – if detention continues – a motion for revocation or modification of the preventive measure.

What are the grounds for applying pre-trial detention?

To effectively contest detention, one must understand why the court applied it. A motion to revoke pre-trial detention should refer to specific grounds, not just a general feeling of injustice.

The following arguments by authorities most frequently arise in detention cases:

• a risk of flight
• a risk of hiding
• a risk of influencing witnesses
• a risk of coordinating versions with others
• a risk of destroying evidence
• threat of severe penalty
• serious nature of the charge
• need to secure proper course of proceedings
• risk of committing a new serious crime

The Code of Criminal Procedure provides, among others, that in the case of a charge of a crime or offence punishable by a penalty with an upper limit of at least 8 years, the threat of a severe penalty may justify the need for pre-trial detention to secure the proper course of proceedings.

However, this does not mean that detention is automatic for a serious charge. The specific situation, evidence, suspect’s behaviour, and possibility of applying milder measures must still be assessed.

Risk of tampering – one of the most common arguments

In practice, the risk of tampering often arises. This concerns the risk that the suspect will influence witnesses, coordinate versions with others, destroy evidence, or obstruct proceedings.

This argument may be strong at the beginning of the case, when witnesses have not yet been questioned, documents have not been secured, or authorities claim the suspect may contact other participants in the event.

But over time, the situation may change.

If:

• key witnesses have already been interviewed
• a phone and computer have been secured
• searches have been conducted
• documents have been collected
• other suspects have been questioned
• the victim has given testimony
• the evidentiary material is already in the files

then it can be argued that the risk of tampering is reduced or can be secured by milder measures.

An example may be a ban on contact with certain persons, police supervision, or a restraining order. If such a measure suffices to secure the proceedings, further detention may be excessive.

Risk of flight or hiding

Another frequent argument is the risk of flight or hiding. Authorities may claim that the suspect will not appear when summoned, will leave the country, or will try to avoid responsibility.

A motion to revoke detention should then demonstrate that such a risk is not real or can be limited by other measures.

The following may be significant:

• permanent place of residence
• family in Poland
• work in Poland
• business activity
• children or dependents
• previous appearances upon summons
• no attempts to flee
• passport issuance
• consent to police supervision
• consent to travel ban
• strong ties to place of residence

Simply stating “I will not flee” is usually insufficient. Facts and documents must be presented. Employment contract, child’s birth certificate, medical documents of a family member, proof of residence, company documents – all these may be relevant if they relate to the court’s specific concern.

Threat of severe penalty

In more serious cases, authorities often cite the threat of a severe penalty. The argument is simple: since the suspect faces a high penalty, they may attempt to flee or obstruct proceedings.

However, such an argument should not be accepted automatically. The mere severity of the potential penalty does not always justify prolonged detention if there are no other real risks or if milder measures can be applied.

The defence may indicate, among other things, that:

• the suspect has a permanent residence in Poland
• did not attempt to flee
• cooperated during proceedings
• voluntarily appeared if such a situation occurred
• did not influence witnesses
• the most important evidence is already secured
• the legal qualification is disputed
• the evidential material is not as strong as claimed by the prosecutor
• milder preventive measures are possible

Therefore, a motion to revoke detention should refer not only to the suspect’s family life but also to whether the threatened penalty truly justifies further isolation in the specific case.

Suspect’s health condition

Health condition may be relevant when assessing pre-trial detention. This does not mean that every illness automatically excludes detention. However, if the person requires specialist treatment, constant care, medication, therapy, or their condition may worsen in isolation, this must be documented.

Useful documents may include:

• medical documentation
• certificates from doctors
• treatment history
• medication list
• hospitalization documents
• specialist opinions
• information on procedures
• documents concerning chronic illnesses
• psychiatric documentation, if relevant
• disability information

It is not enough to state that the suspect “does not tolerate detention well.” Isolation is almost always difficult. A specific health problem and its significance for continued detention must be demonstrated.

In health matters, the role of the family is very important. Relatives often have access to medical documents, medication lists, and contacts to doctors.

Family and professional situation

The family and professional situation alone is not always sufficient to revoke detention, but it can be an important element of the argumentation. The court may consider whether the suspect has a stable life, job, family, caregiving responsibilities, and strong ties to their place of residence.

The following may be significant:

• steady employment
• running a business
• supporting the family
• child care
• plan to start work
• no prior criminal record
• permanent address
• professional duties
• positive employer reference
• documents confirming a stable life

The goal is not to move the court emotionally. It is to demonstrate that the suspect is not a person who intends to flee, hide, or obstruct the proceedings. If this can be proven with documents, the argument is much stronger.

Can a financial surety replace detention?

A financial surety is one of the milder preventive measures. It may involve paying a specified amount of money, securities, or establishing a property guarantee. Its purpose is to discipline the suspect to properly participate in the proceedings.

A motion to replace detention with a financial surety may make sense when it can be shown that the money or assets will realistically secure the suspect’s attendance and proper conduct.

When preparing a surety, it is advisable to include:

• information on who can pay the surety
• the proposed amount
• the source of the money
• documents confirming the ability to pay
• arguments why the surety is sufficient
• possibly combining the surety with police supervision or a travel ban

The mere proposal of a surety is not always enough. If the court believes there is a strong risk of tampering, it may conclude that the money will not secure the proceedings. Therefore, it is often necessary to combine arguments: surety, supervision, contact ban, travel ban, and indication that the most important evidence is already secured.

Police supervision instead of detention

Police supervision is another measure that can replace detention. It involves the obligation to report to a designated police unit at specified times and to comply with other duties imposed by the authority.

Supervision may be appropriate when the court wants to ensure the suspect’s presence in the proceedings but isolation is not necessary.

The motion may indicate that the suspect:

• has a permanent place of residence
• will report for supervision
• will not contact witnesses
• will not leave the country
• will surrender their passport
• will take up or return to work
• will comply with all obligations
• has not previously obstructed the proceedings

Police supervision is often combined with other measures, such as a contact ban, travel ban, or financial surety. In many cases, such a combination can be a realistic alternative to continued detention.

Why the argument “the family needs him” usually is not enough

The family of a detained person often writes emotionally: the children miss him, the wife cannot cope, the business is failing, the parents are ill, everyone needs him at home. All of this may be true and very important in life. However, a motion to revoke detention cannot be based solely on emotions.

The court will primarily ask:

• whether there are grounds for continued detention
• is there still a risk of tampering
• is there still a risk of flight
• does the threatened penalty justify isolation
• have the evidences been secured
• can milder measures be applied
• will the suspect comply with obligations

The family situation may support the argument, but it is rarely sufficient on its own. It must be combined with a procedural assessment: why detention is no longer necessary and what can replace it.

Example of a weaker argument:

“Please release my husband because the children are crying and the business is not operating.”

Example of a stronger approach:

“The suspect has a permanent residence, runs a business in Poland, supports his family, has not attempted to flee, key witnesses have been interviewed, documents secured, and any risks can be mitigated by police supervision, a ban on contact with certain persons, and a financial surety.”

The latter still shows the life situation but refers to reasons why detention would be unnecessary.

What should be included in a motion to revoke detention?

A good motion should be specific. It does not have to be excessively long but must address the actual grounds for detention.

It should usually include:

• designation of the court or authority
• data of the suspect or accused
• case reference number
• indication of what the motion concerns
• request to revoke pre-trial detention
• optionally a request to replace detention with milder measures
• justification
• reference to the grounds for detention
• indication of new circumstances
• arguments against continued isolation
• proposal of alternative measures
• attachments
• signature

The motion should be tailored to the case. It is drafted differently in commercial cases, differently in drug cases, differently in cases of alleged violence, and differently in accidents. Different arguments will be relevant for risk of tampering, risk of flight, or health condition.

That is why in detention cases the most important thing is the analysis of the case files, the detention order, and the court’s reasoning. Without this, the motion may be too general.

The most important initial conclusion

A motion to revoke pre-trial detention makes sense when it can be shown that further isolation is unnecessary or that milder preventive measures suffice. It is not a request written out of emotion. It is a factual letter based on facts, documents, and specific legal grounds.

The key questions are:

• why did the court order detention
• do these reasons still exist
• have new circumstances arisen
• have key evidences been secured
• have witnesses been interviewed
• does the suspect have a permanent residence
• is there a real risk of flight
• is there a real risk of tampering
• can a financial surety be applied
• can police supervision be applied
• can a contact ban or travel ban be applied
• what documents can the family present

Pre-trial detention is very serious but does not close the door to further defence. After detention is applied, one must act quickly, calmly, and concretely. The most important thing is to determine on what basis the court made its decision and what arguments can be presented to show that further isolation is not necessary.

How to prepare a motion to revoke pre-trial detention?

A motion to revoke pre-trial detention should not be a general request for release from detention. Such a document must show the court or prosecutor why further isolation is unnecessary. The key is to address the reasons for which detention was applied.

If the court applied detention due to a risk of tampering, it must be shown that this risk has ceased or can be secured otherwise. If the basis was a flight risk, it must be demonstrated that the suspect has strong ties to the place of residence and does not intend to hide. If the court referred to the threat of a severe penalty, it must be explained why the severity of the charge alone is insufficient to keep the person isolated.

A good motion should answer several questions:

• why pre-trial detention was applied
• do these reasons still exist
• what actions have been taken since detention
• whether key witnesses have been interviewed
• whether documents, phones, computers, or surveillance have been secured
• does the suspect have a permanent residence
• whether the suspect has family, work, or activities in Poland
• is there a real risk of flight
• is there a real risk of tampering
• can police supervision be applied
• can a financial surety be applied
• whether a contact ban can be applied
• whether a travel ban can be applied
• whether there are new circumstances previously unknown to the court

In detention cases, concreteness matters. The family may feel the detention is unfair, but the court will expect procedural arguments. Therefore, it is important to analyze the detention order, its justification, and the evidence already collected.

The basic provisions on preventive measures are found in the Code of Criminal Procedure, whose consolidated text from 2026 is available in ISAP. (isap.sejm.gov.pl)

Why is it necessary to read the detention justification?

It is impossible to write a good motion to revoke detention without understanding why the court applied it. The justification of the order is a map for further defence. It shows which arguments are most important to the court and what must be addressed.

The justification may include, among others, the following grounds:

• high probability of committing the act
• risk of tampering
• a risk of influencing witnesses
• a risk of coordinating versions with others
• a risk of flight
• lack of permanent residence
• threat of severe penalty
• a serious nature of charges
• previous behaviour of the suspect
• need to secure further evidentiary actions

If the motion does not address these arguments, it will be weak. For example, if the court applied detention due to a risk of influencing witnesses, and the defence writes only that the suspect has children and a job, that may be insufficient. The family situation is important but does not automatically remove the risk of tampering.

The motion should show what has changed since detention was applied. If witnesses have already been interviewed, phones secured, documents secured, searches conducted, or surveillance collected, this should be emphasized. Then it can be argued that further isolation is no longer necessary.

New circumstances – why are they so important?

A motion to revoke or modify pre-trial detention is stronger when new circumstances arise. These are facts the court did not previously know or that occurred after detention was applied.

A new circumstance may be, for example:

• interviewing the most important witnesses
• securing key evidence
• obtaining medical documentation
• presenting a financial surety
• presenting documents of permanent employment
• documenting care for a child or a sick person
• deterioration of the suspect's health
• establishing a permanent residence address
• proposal for police supervision and contact prohibition
• change of legal qualification
• weakening of evidence material
• prolonged inactivity in the case

Not every new document automatically leads to the lifting of detention. But without new arguments, the motion may be treated as a repetition of the previous position.

Example of a weak approach:

“I request the lifting of detention because the suspect does not admit guilt and wants to return to the family.”

Example of a stronger approach:

“Since the detention was applied, key witnesses have been interviewed, the suspect's phone and documentation from the scene have been secured, and the suspect no longer has a real possibility to influence the evidence. Any potential risks can be mitigated by police supervision and a prohibition on contact with specified persons.”

In detention cases, the difference between emotion and argument is significant.

How to demonstrate that the risk of tampering has ceased?

The risk of tampering is one of the most common reasons for applying detention. Authorities may claim that the suspect will influence witnesses, coordinate versions with others, destroy evidence, or obstruct proceedings.

A motion to lift detention should then show that such a risk does not exist or that it can be secured otherwise.

Arguments may include:

• key witnesses have already been interviewed
• the victim has already given testimony
• a phone and computer have been secured
• a search has been conducted
• documents have been secured
• surveillance has been secured
• other suspects have been questioned
• the suspect has not attempted to contact witnesses
• a prohibition on contact with specific persons can be applied
• police supervision can be applied
• a restraining order can be applied
• a financial surety can be applied

The court may not agree to a complete lifting of preventive measures but may find that detention can be replaced with a milder measure. Therefore, it is worth proposing specific alternatives.

If the case concerns contact with the victim or witnesses, it is very important that the family and the suspect do not undertake actions that may appear as pressure. Contacting witnesses after detention may weaken the argument and increase the risk of tampering.

How to demonstrate that there is no risk of flight?

If the court referred to the risk of flight or hiding, the motion should show that the suspect is connected to Poland and a specific place of residence. Documents are particularly important here.

Useful documents may include:

• confirmation of permanent address
• rental agreement or property ownership document
• employment contract
• certificate from employer
• business activity documents
• information about family living in Poland
• children's birth certificates
• documents concerning family care
• medical documents of relatives
• treatment certificates
• confirmation of passport surrender
• proposal of a travel ban
• proposal for police supervision

It is necessary to demonstrate that the suspect is not a person who will disappear after being released from detention. If the suspect has previously appeared upon summons, cooperated during proceedings, or did not attempt to flee during arrest, it is also worth indicating this.

A mere assurance of "I will not flee" is usually insufficient. The court requires specifics. The more documents showing a stable life, the better.

Financial surety as an alternative to detention

Financial surety can be an important element of a motion to change pre-trial detention. It involves depositing a specified amount of money, securities, or other collateral intended to discipline the suspect to properly participate in the proceedings.

The Code of Criminal Procedure provides for the possibility of changing pre-trial detention on condition of posting a specified financial surety. The court may set a deadline for posting the surety, and upon a justified request by the accused or defense counsel, this deadline may be extended.lexlege.pl)

When submitting a financial surety, it is advisable to specify:

• who is posting the surety
• the proposed amount
• the source of the funds
• whether the money is immediately available
• whether the surety is posted by family
• whether other collateral is possible
• why the surety will effectively discipline
• whether the surety can be combined with police supervision
• whether the surety can be combined with a travel ban

The amount of the surety should not be arbitrary. Too low an amount may not convince the court that it effectively secures the proceedings. Too high an amount may be impossible to pay. The motion should be realistic.

It is also important to remember that financial surety does not always solve the problem. If the main basis for detention is a very strong fear of evidence tampering, the court may find that money alone is insufficient. In such cases, it is advisable to combine the surety with other measures, such as a contact ban, police supervision, and a travel ban.

Police supervision instead of pre-trial detention

Police supervision is one of the most commonly proposed alternative measures to detention. The suspect remains at liberty but is obliged to regularly report to the police station and comply with imposed duties.

Supervision can be a good argument when the court fears the suspect will not appear upon summons or when behavior needs to be monitored but isolation is not necessary.

The motion may propose:

• regular reporting to the police station
• a ban on leaving a specified place of residence
• an obligation to inform about address changes
• a ban on contact with witnesses
• a ban on contact with the victim
• a ban on being present in specified locations
• combining supervision with financial surety
• combining supervision with a travel ban

It is advisable to demonstrate that the suspect will be able to comply with supervision. If the suspect has a permanent residence, family, employment, and has not attempted to flee, supervision may be more convincing.

In criminal cases, such a motion should be part of a broader strategy, as the mere proposal of supervision is not always sufficient. It is necessary to show why supervision secures the same objectives as detention but in a less burdensome manner. criminal defenceContact ban and restraining order

If the court fears influence on witnesses or the victim, it is possible to consider proposing a contact ban or restraining order. Such a measure may be particularly important in cases involving violence, family conflicts, threats, harassment, crimes against liberty, or cases with multiple participants.

will not contact specified persons

The motion may indicate that the suspect:

• will not approach the victim
• will not be present in specified locations
• will not communicate via phone, internet, or third parties
• will not communicate by phone, internet, or through third parties
• will comply with all obligations
• may be subject to police supervision

Such an argument makes sense when the main risk is contact with specific persons. If this risk can be limited by a contact ban, the court may consider whether further detention is necessary.

But caution is required. If after detention the family or the suspect tried to contact the victim or witnesses, the argument for a contact ban may be weaker. Therefore, from the very beginning, actions that may appear as pressure must be avoided.

Ban on leaving the country and passport retention

If the court fears flight abroad, a ban on leaving the country and passport retention can be proposed. Such a measure may be combined with police supervision and a financial surety.

Arguments may be as follows:

• the suspect has a permanent residence in Poland
• has family in Poland
• has a job or business in Poland
• has no real plans to leave
• will surrender their passport
• agrees to the ban on leaving the country
• agrees to police supervision
• will inform about change of residence

Such a set of measures may show that the risk of flight can be secured without isolation. Of course, everything depends on the case. If the suspect previously hid, left without notice, or has strong ties abroad, the argument must be much stronger.

Documents the family can collect

The family of a person in pre-trial detention can realistically help by collecting documents needed for the application. This is not about writing emotional letters, but materials showing the suspect’s situation.

Useful documents may include:

• employment certificate
• employment contract
• business activity documents
• income certificate
• documents confirming permanent residence
• rental agreement
• property deed
• children's birth certificates
• documents concerning child care
• medical documents of the suspect
• medical documents of family members
• treatment certificates
• employer’s opinion
• documents confirming education
• documents concerning family obligations
• confirmation of ability to pay surety
• documents concerning the source of money for the surety

Such documents may show that the suspect has a stable life, responsibilities, family, and a place to return to. They can also help demonstrate that there is no real risk of flight or hiding.

The family should not independently contact witnesses, victims, or other suspects. This may do more harm than good.

Medical documents in the application for release from detention

Health condition may be an important argument, but only if well documented. Simply stating that the detained person feels unwell is usually insufficient. Detention is mentally and physically difficult for most people, so the court will expect specifics.

Useful documents include:

• medical history
• hospital discharge summaries
• certificates from specialists
• medication list
• documents concerning chronic illnesses
• information about planned procedures
• psychiatric documentation, if relevant
• disability certificate
• documents confirming the necessity of permanent care
• documents concerning therapy

The application should explain why the health condition is relevant to the continued use of detention. It is not sufficient to attach documents without commentary. It is necessary to demonstrate whether treatment is possible in isolation, whether detention worsens the health condition, and whether there are reasons why further isolation is disproportionate.

Work and business as an argument

Work or running a business may be important, but not because they alone guarantee release from detention. They matter when they demonstrate life stability, ties to the place of residence, and no real risk of flight.

For employment, it is advisable to prepare:

• employment contract
• certificate from employer
• information about the position
• information about length of service
• confirmation that the employer is willing to rehire the suspect after release
• documents concerning professional duties
• documents showing financial responsibility for the family

For business activity, the following may help:

• entry in CEIDG or KRS
• company documents
• contracts with contractors
• accounting documents
• information about employees
• documents showing that the company requires the suspect's presence
• documents showing the risk of company collapse if detention continues

The point is not for the court to consider the entrepreneur more important than another person. It is to show that the suspect has reasons to remain in the country, respond to summonses, and fulfill procedural obligations.

Care for a child or a sick person

Family obligations may be relevant, especially when the suspect has actually cared for a child, a sick, disabled, or elderly parent. However, it is necessary to distinguish ordinary family longing from a specific caregiving duty.

Useful documents may include:

• children's birth certificates
• documents concerning cohabitation
• disability certificate of a family member
• medical documents of the person requiring care
• certificates from school or kindergarten
• documents confirming that the suspect actually provided care
• statements or documents showing the absence of another caregiver

Such an argument may support the application but should be well documented. The court must see that it is not just about general family hardship but a real duty seriously affected by continued detention.

Is it possible to renew an application for release from detention?

An application for release or modification of pre-trial detention may be renewed, but it should not be done mechanically without new arguments. If the subsequent submission repeats exactly the same content as the previous one, chances may be slim.

A renewed application makes more sense when:

• new evidence has appeared
• additional witnesses have been interviewed
• evidentiary material has been secured
• the health situation has changed
• the family situation has changed
• there is a possibility of a financial surety
• the proceedings are prolonged
• the prosecutor does not perform essential actions
• the legal qualification has changed
• the grounds for detention have weakened
• previous concerns of the court have become outdated

Each subsequent motion should bring something new. This may be a new document, a new action in the case, a change in personal circumstances, or a new proposal for an alternative measure.

How to combine several measures instead of detention?

In many cases, the best solution is not merely to request the revocation of detention, but to propose a set of measures that will secure the proceedings without isolation.

One may propose, for example:

• police supervision
• financial surety
• ban on leaving the country
• passport retention
• a ban on contact with witnesses
• a ban on contact with the victim
• restraining order
• an obligation to inform about a change of residence
• a ban on being present in specified locations

Such a set may be more persuasive than a mere request for release. It shows the court that the defense does not ignore risks but proposes securing them in a less burdensome way.

Example:

“Instead of pre-trial detention, a financial surety, police supervision three times a week, a ban on leaving the country combined with passport retention, and a prohibition on contact with specified witnesses may be applied.”

This is concrete. The court may disagree, but it has a real alternative before it.

What to avoid in the motion?

In a motion to revoke detention, it is advisable to avoid empty slogans, aggression, and emotions without arguments. The court will not assess the case based on who writes more dramatically. What matters are the grounds for detention and the possibility of challenging them.

It is not advisable to base the motion solely on statements such as:

• the suspect is innocent
• the family suffers
• the children cry
• the company is failing
• the detention is unjust
• the prosecutor is wrong
• the witnesses lie
• the suspect promises to behave
• everyone vouches for him

Some of these things may be relevant, but only when combined with specific procedural arguments.

Better to write:

• what evidence has been secured
• what actions have already been taken
• which court concerns have ceased
• what documents confirm the suspect’s stability
• what alternative measures can be applied
• why further detention is disproportionate
• what new circumstances have arisen after detention was applied

A good motion should be calm and factual. Family emotions are understandable, but in procedural documents they must give way to arguments.

Motion and contact with the defense attorney

A motion to revoke pre-trial detention is best prepared after the defense attorney has analyzed the case. This is for a simple reason: one must know exactly what is in the case files, what the grounds for detention were, and what actions have been taken since its application.

The family can gather documents, provide information, prepare data about work, health, children, and surety. But it is the defense attorney who should assess how to use this information procedurally.

In detention cases, legal assistance is particularly urgent because time works against the isolated person. The longer the detention lasts, the greater the impact on family life, work, business, and the suspect’s psyche.

If a close person has been pre-trial detained, contact can be initiated through the website contactstating the case number, court or prosecutor's office, date of detention, duration of detention, and whether a complaint has already been filed.

Key conclusions from preparing the motion

The motion to revoke pre-trial detention should be specific, tailored to the case, and based on documents. The biggest mistake is writing a general request that does not address the reasons for the detention.

the sentence must qualify for SDE

• analysis of the justification for detention
• indication of which grounds for detention have ceased
• presentation of new circumstances
• demonstration that evidence has been secured
• arguments against the risk of tampering with evidence
• arguments against the risk of flight
• family, professional, and medical documents
• proposal of a financial surety
• proposal for police supervision
• proposal of a contact ban or travel ban
• calm, factual language

The more the motion addresses the court's real concerns, the more meaningful it is. It is not about merely convincing that the detainee should return home. It is about showing that further deprivation of liberty is unnecessary because the proceedings can be secured by other means.

The role of the family after pre-trial detention is applied

Pre-trial detention affects not only the suspect. It also strongly impacts the family. Relatives often remain without information, without documents, without access to the detainee, and without knowledge of what to do next. In an instant, they must manage the criminal case, work, children, housing, business, loans, medication, contact with the defense attorney, and basic formalities.

The worst thing to do then is to act chaotically. The family wants to help, but in emotional turmoil may make mistakes that later complicate the defense. Therefore, after detention is applied, calm, order, and quick gathering of information are paramount.

The family should determine:

• who issued the decision on pre-trial detention
• which court considered the prosecutor's motion
• what is the case number
• for what period was detention applied
• was the defense attorney present at the hearing
• has a complaint been filed
• where is the detainee located
• does the detainee have medication or illnesses
• is it necessary to secure professional matters
• is it necessary to secure children or dependents
• are there documents needed for the motion to revoke detention
• is a financial surety possible
• is it necessary to quickly gather medical documentation

In detention cases, time is of the essence. If the deadline for filing a complaint is still running, action must be taken very quickly. If a complaint has already been filed or dismissed, a motion to revoke or modify detention can be prepared, but it should contain specific arguments, not just a repetition of earlier requests.

If a close person was detained after a prior arrest, it is worth reconstructing the entire course of the case from the beginning. Circumstances described at police arrestmay be significant, as the initial actions, protocols, explanations, and contact with the defense attorney often influence the later assessment of the case.

How can the family help the defense attorney?

The family cannot replace the defense attorney but can greatly assist in preparing materials. The defense attorney handles procedural arguments, file analysis, pleadings, and court appearances. The family can collect documents that the detainee does not have with them and which the lawyer often cannot obtain alone within a few hours.

Useful documents may include:

• employment contract
• certificate from employer
• business activity documents
• company documents
• confirmation of permanent residence
• rental agreement or property deed
• children's birth certificates
• documents concerning child care
• medical documents of the detainee
• medication list
• medical documents of family members
• disability rulings
• treatment certificates
• employer’s opinion
• documents confirming the possibility of posting bail
• documents showing the source of funds for bail
• information about fixed obligations
• documents confirming previous attendance at summonses

Such documents may demonstrate that the detainee has a stable life, permanent address, family, job, responsibilities, and reasons to participate in the proceedings without fleeing or hiding. They may also help show that continued detention causes particularly serious health, family, or professional consequences.

However, it should be remembered that documents alone are not sufficient. They must be linked to the grounds for detention. If the court feared flight risk, documents about work and family may be very important. If the court feared tampering, it may be more significant that witnesses have been questioned, evidence secured, and the risk of contact can be limited by a contact ban.

What should the family avoid doing after detention?

After detention, emotions run high. The family wants to “save” their loved one and sometimes does things that seem helpful but may actually cause harm.

Do not:

• contacting witnesses to establish versions of events
• asking the victim to change statements
• deleting messages, documents, or files
• cleaning the phone or computer
• remove items from the apartment or business without consultation
• posting comments about the case online
• threatening persons connected to the case
• disclosing case details to random persons
• writing emotional letters to the court without consulting the defence attorney
• encouraging anyone to give specific testimony
• contacting other suspects
• violating contact bans if imposed

Influencing witnesses is particularly dangerous. Even if the family believes they only want to “clarify the matter,” authorities may interpret such actions as an attempt to tamper. This can hinder the lifting of detention, as the fear of tampering is often one of the main reasons for isolation.

If someone has important information, documents, or recordings, it is best to pass them to the defence attorney. The lawyer should assess how to safely use them in the case.

Contact with a person in pre-trial detention

After detention is imposed, contact with the loved one is limited. The family often does not know when they can call, write a letter, or obtain permission for a visit. It should be remembered that pre-trial detention is procedural isolation, and contact with the detainee is subject to specific rules.

In practice, the family may be interested in:

• where the detainee is held
• whether a letter can be sent
• whether permission is needed for a visit
• who grants permission for a visit
• whether a package can be delivered
• whether money can be transferred
• whether the detainee has access to medication
• whether the defence attorney has contact with the detainee
• whether the detainee knows the content of the complaint or motion
• whether family or medical documents are needed

Family contact with the detainee may be difficult, but contact with the defence attorney is particularly important. The defence attorney can discuss the case with the detainee, establish a position, prepare documents, and inform the family to the extent possible and agreed upon.

The family should avoid including content in correspondence that may be misunderstood. Letters should not contain suggestions regarding witnesses, versions of events, deleting documents, or pressure on others. Even if the intention is innocent, the content may be assessed in the broader context of the case.

Visiting a person in pre-trial detention

A visit with a person in pre-trial detention usually requires the consent of the competent authority. In preparatory proceedings, decisions in this regard are most often associated with the prosecutor conducting or supervising the case. In court proceedings, the situation is different because the case is already before the court.

The family should determine:

• where the detainee is located
• who is handling the case
• is the case at the prosecutor's office or the court stage
• to whom to address the visitation request
• what information must be provided in the request
• can the visitation be one-time or multiple
• are there contact restrictions
• is there a risk of refusal due to the interests of the proceedings

Not every refusal of visitation means that nothing can be done. Sometimes the request can be renewed, sometimes one must wait for certain actions to be completed, and sometimes it is worth consulting with the defence attorney whether the refusal is justified.

In cases where the main basis for detention is the risk of tampering, authorities may be more cautious about contacts. Therefore, the family should act formally and not try to bypass procedures through acquaintances or third parties.

Letters, packages, and money

After detention, the family often wants to send basic items as soon as possible. However, before sending anything, it is advisable to check the rules of the specific facility and the stage of the case. Different rules may apply to correspondence, packages, and monetary deposits.

Most often, the family wants to send:

• clothing
• hygiene products
• glasses
• medical documents
• a list of medications
• money for release
• books
• correspondence
• information about children and family

Care must be taken not to discuss the case in a risky manner in letters. One should not write about:

• what witnesses should say
• who should change their version
• which messages were deleted
• what the family did with the phone or documents
• how to "set up" the case
• who should talk to whom
• that someone should not appear for interrogation

It is safest to write briefly, calmly, and familiarly, and discuss procedural matters with the defence attorney.

Role of the defence attorney in detention cases

The defence attorney in detention cases plays a very important role because detention concerns a person's liberty even before a final judgment. This is not an ordinary letter or formality. Every decision can affect whether the suspect remains in isolation or the court agrees to milder measures.

The defence attorney can:

• analyze the detention order
• check the grounds for isolation
• file a complaint
• prepare a motion to revoke detention
• prepare a motion to change detention to milder measures
• indicate new circumstances
• collect documents from the family
• communicate with the detainee
• participate in hearings
• respond to the extension of detention
• submit evidentiary motions
• develop further defense strategy

In detention cases, it is very important to combine two levels: legal and practical. On one hand, one must know the provisions and grounds for detention. On the other hand, one must understand the real situation of the suspect: family, work, health, documents, risk of flight, contact with witnesses, and the stage of the case.

Therefore criminal defence detention should be challenged quickly, concretely, and based on documents, not just on the general belief that the detention is unjust.

Complaint against pre-trial detention and subsequent motion

After pre-trial detention is applied, the first step is often a complaint. The complaint serves to challenge the specific court decision ordering detention. The deadline must be observed, as it is an appeal measure related to a specific decision.

A motion to revoke or change detention may be filed later. Its purpose is for the defense to indicate that further detention is unnecessary because the grounds for isolation have ceased or new circumstances have arisen.

In practice, the following scheme is possible:

• the court orders pre-trial detention
• the defense files a complaint
• the appellate court considers the complaint
• if detention is upheld, the defense analyzes further options
• after performing additional actions or gathering documents, a motion to revoke or change detention is submitted
• upon extension of detention, the defense again challenges the necessity of isolation

The complaint and subsequent motion will not always be based on the same arguments. The complaint may concern errors made by the court when initially ordering detention. The later motion may be based on the fact that witnesses have been heard, evidence secured, health has deteriorated, or the family has collected a financial surety.

Extension of pre-trial detention

Pre-trial detention is applied for a specified period. If authorities want it to continue, they must apply for its extension. This is a very important moment because the court should reassess whether further isolation is necessary.

When extending detention, it should not be sufficient to automatically repeat previous arguments. Over time, one must ask:

• what actions have been taken
• have witnesses been interviewed
• whether evidence has been secured
• whether the proceedings are conducted efficiently
• whether the risk of tampering still exists
• whether the risk of flight is real
• whether detention has lasted too long
• can milder measures be applied
• whether new documents have appeared
• whether the suspect's health condition has changed

The longer detention lasts, the greater the importance of proportionality. Detention should not be maintained merely because it was previously applied. Each further deprivation of liberty should have a current justification.

In practice, the extension of detention is the moment when the defense should very carefully verify whether the prosecution is indeed conducting the case efficiently and whether reasons for isolation still exist.

Subsequent motions to revoke detention

A motion to revoke pre-trial detention can be repeated, but it must be done sensibly. Filing the same document every few days without new arguments usually achieves little.

A subsequent motion has greater significance when something new has occurred:

• an important witness has been heard
• documents have been secured
• an expert opinion has been obtained
• the health condition has changed
• a financial surety has been collected
• new family documents have appeared
• the proceedings are prolonged
• the prosecutor does not perform essential actions
• the legal qualification has changed
• the appellate court has indicated important arguments
• the risk of tampering has actually decreased

Each subsequent application should answer the question: what has changed since the previous decision?

If nothing has changed, one must carefully assess whether submitting another document makes sense. Sometimes it is better to wait for a specific action to be taken or to gather stronger documents than to submit a weak application just to "do something."

Errors in applications for release from detention

Certain errors recur in detention cases. They most often stem from family emotions or from drafting the application without analyzing the court's reasoning.

The most common mistakes are:

• writing exclusively emotional pleas
• lack of reference to grounds for detention
• lack of new circumstances
• lack of documents
• repeating arguments from the complaint without changes
• attacking the court or prosecutor
• omitting the risk of tampering
• omitting the risk of flight
• making general promises without safeguards
• lack of proposals for milder measures
• lack of surety despite the possibility of offering one
• failure to demonstrate a permanent place of residence
• lack of medical documents when health arguments are made
• submitting successive identical applications

The application should not read like a begging letter. It should be a procedural document. It may show the family's distress, but above all it must answer the question: why is further detention unnecessary?

Error: focusing only on innocence

The family often says: "he is innocent, so he must be released." This is understandable, but in detention cases it is not always sufficient. At the pre-trial detention stage, the court does not yet decide on guilt as in a verdict. The court assesses, among other things, the likelihood of the offense and the need to secure the proceedings.

Therefore, the application cannot be based solely on the claim that the suspect is innocent. One must also refer to the grounds for detention.

Of course, one can point out that the evidence is weak, contradictory, or does not justify detention. But this must be done specifically. If there is evidence undermining the charge, it must be indicated. If a witness has changed testimony, it must be described. If surveillance shows something else, it must be mentioned. If the legal classification is too harsh, it must be challenged.

The mere statement "the suspect did not do it" is usually insufficient.

Error: emotional letters from family

The family often wants to write their own letter to the court. Mother, wife, partner, children, siblings—everyone wants to show that the detainee is needed at home. Such letters may be significant, but care must be taken that they do not replace proper argumentation.

An emotional letter may show:

• the family situation
• child care
• illness of loved ones
• the impact of detention on the business
• the suspect's previous life
• his permanent place of residence
• the family's readiness to provide surety

But it should not contain:

• attacks on the court
• attacks on the prosecutor
• pressure on witnesses
• claims without knowledge of the case files
• information about “version establishing”
• empty promises
• threats or complaints
• description of evidence unknown to the family

It is best if such materials are agreed upon with the defence counsel. Sometimes it is better to attach a short, factual statement or document than a long letter full of emotions.

Mistake: contact with the victim after detention

If the basis for detention is the risk of tampering, contact between the family and the victim or witnesses can be very harmful. Even if the family only wants to “talk,” the other party may perceive it as pressure.

Particularly risky are messages such as:

• “withdraw the case”
• “tell the truth because he is in jail”
• “he ended up in detention because of you”
• “think about what you are doing”
• “let’s make a deal”
• “don’t exaggerate in your testimony”
• “change what you said”
• “don’t go to the prosecutor’s office”
• “say it was a mistake”

Such actions may be used as an argument for continued detention. The court may find that since the family is trying to influence persons involved in the case, the risk of tampering remains valid.

If there is a need for any contact with the victim, it must first be discussed with the defence counsel. In many cases, no contact is the safest option.

Mistake: ignoring alternative measures

Sometimes the family focuses only on one goal: complete revocation of detention. Meanwhile, in some cases, a more realistic option may be to replace detention with a set of milder measures.

It is worth considering:

• police supervision
• financial surety
• ban on leaving the country
• passport retention
• a ban on contact with witnesses
• a ban on contact with the victim
• restraining order
• the obligation to inform about the place of residence

Such measures may be a safer alternative for the court than fully lifting all restrictions. If the motion shows that the defence understands the risks and proposes specific safeguards, it may be more persuasive.

This is especially important in cases where the court still sees certain risks but they do not necessarily require isolation. A well-prepared motion should therefore include not only the main demand but also a proposal for an alternative solution.

What to do if the court refuses to revoke detention?

Refusal to revoke detention does not always end the possibilities for action. However, it is necessary to calmly analyse why the court refused. The reasoning for refusal may show which arguments were insufficient and what is missing.

After refusal, it is worth checking:

• which grounds for detention the court still considers valid
• whether the court addressed new circumstances
• whether the court found the documents insufficient
• whether the problem was the risk of tampering
• whether the problem was the risk of flight
• whether the court considered alternative measures
• whether new documents can be gathered
• whether further evidentiary actions were performed
• whether the detention extension deadline is approaching
• whether it is possible to submit another motion after a change in circumstances

It is not advisable to automatically respond with another identical letter. It is better to determine what can realistically be improved. Sometimes it is necessary to wait for witness hearings. Sometimes to gather stronger documents. Sometimes to propose a higher bail. Sometimes to focus on a complaint against the detention extension.

Prolonged detention and the pace of proceedings

Over time, the pace of proceedings becomes very important. Detention should not last simply because the case is difficult or the authorities are slow. If the suspect is isolated, the authorities should conduct the case efficiently.

The defence may draw attention to whether:

• the prosecution is performing real actions
• witnesses are being questioned
• documents have been secured
• an expert opinion is awaited
• delays are justified
• the case truly requires further isolation
• detention does not become excessively burdensome
• the proceedings cannot be secured in a milder way

The longer the detention lasts, the more one must ask whether it is still necessary. Grounds that may have been valid at the beginning may look different after several months. If evidence is secured, witnesses questioned, and the suspect has a permanent residence and the possibility of bail, further isolation requires current justification.

Detention case and further criminal defence

A motion to lift detention is only one element of the case. At the same time, one must consider the entire criminal defence. Detention is very important because it concerns freedom, but one must not lose sight of the charges and evidentiary material.

The defence should analyse:

• the content of the charges
• legal qualification
• prosecution evidence
• witness testimonies
• suspect’s explanations
• secured documents
• phone and correspondence
• monitoring
• expert opinions
• legality of actions
• possible evidentiary motions
• strategy for further questioning
• risk of indictment

Sometimes the fight to lift detention requires showing that the evidentiary material is not as strong as the prosecutor claims. Sometimes the most important are procedural arguments related to the absence of risk of tampering. Sometimes one must prepare for both at once.

Therefore, cases concerning pre-trial detention should be conducted not only as a fight for release but also as part of a broader defence strategy.

What to prepare before talking to a lawyer?

Before contacting a lawyer, the family does not need to have everything. It is important to have basic information and documents that will allow a quick assessment of the situation.

Prepare:

• the full name of the detainee
• date of birth or PESEL
• case reference number, if known
• name of the court
• name of the prosecution office
• date detention was applied
• period for which detention was applied
• information whether there was a complaint
• information whether the defence counsel was present at the hearing
• copy of the detention order
• justification, if available
• family documents
• professional documents
• medical documents
• information about the possibility of bail
• contact details of a family member

If the documents are not available, it is still worth making contact. In detention cases, one cannot always wait for the family to obtain a complete set. Often, the most urgent steps must be determined first, while gathering documents simultaneously.

Key conclusions from actions after detention

After the application of pre-trial detention, the most important thing is to organize the situation. It is necessary to establish why the court applied detention, what the deadlines are, whether a complaint has been filed, what documents can be collected, and whether there are grounds for a motion to revoke or change the detention.

The family can help if it acts calmly and concretely. It can collect documents, establish information, support contact with the defence counsel, prepare a surety, and take care of health or family matters. However, it should not contact witnesses, delete data, publish the case online, or attempt to act outside the procedure.

The most important questions after detention are:

• whether the deadline for a complaint is still running
• what were the grounds for applying detention
• whether the risk of tampering still exists
• whether the risk of flight is real
• have witnesses been interviewed
• whether evidence has been secured
• whether a financial surety can be proposed
• whether police supervision can be proposed
• whether a contact ban can be proposed
• whether there are family, professional, or medical documents
• whether detention should be replaced by a milder measure

Pre-trial detention is serious but does not mean the end of the defence. In many cases, only after the court’s first decision does intensive work begin: analysis of the files, collection of documents, preparation of arguments, further motions, and the fight to ensure that isolation does not last longer than is truly necessary.

Common mistakes in the fight to revoke pre-trial detention

A motion to revoke pre-trial detention can be a very important defence tool, but only if it is well prepared. In detention cases, it is not enough to write that the suspect wants to return home, the family suffers, and the business does not operate. These are important life circumstances, but the court will primarily look at whether the grounds for isolation still exist.

The most common mistakes stem from emotions, haste, or misunderstanding how pre-trial detention differs from a sentence. The family often perceives detention as a verdict. The suspect feels the need to immediately explain everything and prove innocence. Meanwhile, in detention cases, one must act differently: calmly, factually, and procedurally.

The most common mistakes are:

• submitting a general motion without reference to the grounds for detention
• writing only about the family situation
• lack of documents
• lack of proposals for milder measures
• omitting the risk of tampering
• omitting the risk of flight
• submitting successive identical applications
• contacting witnesses
• deleting messages or documents
• attacking the court or prosecution
• lack of analysis of the reasoning in the decision
• reacting too late to the extension of detention
• confusing a complaint with a motion to revoke detention

Each of these mistakes can weaken the chances of changing the preventive measure. Therefore, before preparing the document, it is necessary first to establish why the court applied detention and what can realistically be opposed to it.

Mistake: writing only about the family

The family of a person in pre-trial detention experiences enormous stress. Children ask when the parent will return. The partner is left with bills, the business, childcare, or a loan. The parents of the detained person fear for their health. All this is real and important.

The problem is that describing the family’s suffering alone is usually insufficient to revoke detention.

The court will ask:

• whether there is still a risk of tampering with evidence
• whether there is still a risk of flight
• have the evidences been secured
• whether witnesses have been interviewed
• whether the suspect can influence the proceedings
• can police supervision be applied
• can a financial surety be applied
• whether a contact ban can be applied
• whether further detention is proportional

The family situation should therefore strengthen the argumentation, not replace it. If the suspect cared for a child, this must be documented. If they supported the family, it is worth showing documents. If detention causes serious health or caregiving consequences, specific certificates must be presented.

Instead of writing only:

“The family suffers greatly and asks for release.”

it is better to show:

“The suspect has a permanent residence, employment, family in Poland, has not attempted to flee, key witnesses have been interviewed, and any risks can be secured by police supervision, a contact ban, and a financial surety.”

This still shows the family situation but simultaneously addresses the procedural grounds for detention.

Error: lack of documents

In detention cases, documents are of great importance. The court does not have to take at face value that the suspect works, is ill, takes care of a child, or has a permanent address. If these facts are to support the motion, they must be documented.

The motion may include, among others:

• employment contract
• certificate from employer
• business activity documents
• company documents
• confirmation of permanent residence
• a lease agreement
• property deed
• children's birth certificates
• medical documents of the suspect
• medical documents of family members
• disability rulings
• medical treatment documents
• documents confirming the possibility of posting bail
• confirmation of the source of funds for bail
• employer opinions
• certificates from the children's school or kindergarten

Documents should be legible and tailored to the arguments. If the motion refers to health, medical documentation must be attached. If it refers to employment, proof of employment must be shown. If bail is proposed, it must be demonstrated that the funds are real.

Lack of documents means that even true arguments may appear weak.

Error: ignoring the risk of tampering

The risk of tampering is one of the most common grounds for pre-trial detention. It concerns the risk of influencing witnesses, coordinating versions, destroying evidence, or obstructing proceedings.

If the court applied detention for this reason, the motion to revoke must address it. It is not enough to write that the suspect has a family and wants to return home. It is necessary to show why there is no longer a real possibility of obstructing the case or why it can be secured in a milder way.

Arguments may include:

• key witnesses have been interviewed
• the victim has given testimony
• a phone and computer have been secured
• documents have been secured
• searches have been conducted
• surveillance has been secured
• other suspects have been questioned
• a contact ban can be applied
• a restraining order can be applied
• police supervision can be applied
• a financial surety can be applied

The behavior of the family is also very important. If relatives call witnesses after detention, write to the victim, or try to "settle the matter," they may effectively strengthen the argument of tampering. This may hinder the revocation of detention.

Error: lack of a real alternative to detention

Sometimes the motion is limited to the demand: "revoke detention." The problem is that the court may still see certain risks. In that case, it is worth proposing alternative measures.

Possible alternatives include, among others:

• police supervision
• financial surety
• ban on leaving the country
• passport retention
• a ban on contact with witnesses
• a ban on contact with the victim
• restraining order
• the obligation to inform about the place of residence
• a ban on being present in specified locations

A well-prepared motion may contain a main and an alternative demand. For example: revocation of pre-trial detention, and if the court does not find this justified - changing detention to police supervision, bail, a ban on leaving the country, and a ban on contact with specified persons.

This way of arguing shows that the defense does not ignore risks. It shows that the proceedings can be secured without further isolation.

Error: repeating identical motions

A motion to revoke or change pre-trial detention can be repeated, but each subsequent filing should bring something new. Filing the same motion every few days usually does not increase chances if nothing has changed.

New arguments may arise from the fact that:

• additional witnesses have been interviewed
• documents have been secured
• an expert opinion has been performed
• new medical documentation has been obtained
• the possibility of bail has appeared
• the family situation has changed
• the proceedings are prolonged
• the prosecutor does not perform essential actions
• the grounds for the charge have weakened
• the legal qualification has changed
• the court in the previous justification indicated what was missing

Each subsequent motion should answer the question: what has changed since the last decision?

If the answer is "nothing," it is worth first gathering new documents or waiting for the performance of an important action. A weak, repetitive motion may reinforce an unfavorable assessment of the case.

Complaint against pre-trial detention

After pre-trial detention is applied, the first step is often a complaint. This is a remedy by which the court's decision to apply detention can be challenged. The complaint is time-limited, so prompt action is necessary.

The complaint may indicate, among others, that:

• there were no grounds for detention
• the court incorrectly assessed the evidence
• there is no high probability of committing the act
• the risk of tampering is unfounded
• the risk of flight is unfounded
• The threatened penalty does not justify isolation
• Milder measures can be applied
• The court did not sufficiently consider alternatives to detention
• The justification is too general
• The suspect's personal situation speaks against detention

A complaint and a motion to revoke detention are not the same. A complaint concerns a specific court decision. A motion to revoke or change detention concerns the further application of this measure and may also be based on later circumstances.

In practice, both actions can complement each other. First, the defense attorney may file a complaint, and later—when new arguments arise—a motion to revoke or change detention.

Extension of pre-trial detention

Pre-trial detention is applied for a specified period. If authorities want it to continue, they must apply for its extension. This is a very important moment because the court should reassess whether further isolation is necessary.

When extending detention, it is necessary to check:

• what actions have been taken since the previous decision
• have witnesses been interviewed
• whether evidence has been secured
• whether the prosecution is acting efficiently
• whether the risk of tampering still exists
• whether the risk of flight still exists
• whether the threatened penalty remains the main argument
• can milder measures be applied
• whether detention is not becoming excessively long
• whether the health or family situation has changed

Detention should not be extended automatically just because it was previously applied. Over time, the court should examine whether the grounds for isolation remain valid.

If the case is prolonged and the prosecution does not perform essential actions, this may be an argument for changing detention to a milder measure. Detention should not replace efficient conduct of proceedings.

What to do if the court refuses again?

Refusal to revoke detention is difficult for the family but does not always mean the end of possible actions. However, conclusions must be drawn from the justification.

After refusal, it is worth checking:

• which grounds for detention the court still considers valid
• whether the problem is the risk of evidence tampering
• whether the problem is the risk of flight
• whether the court found the documents insufficient
• whether the court addressed bail
• whether the court considered police supervision
• whether new circumstances are lacking
• whether it is necessary to wait for witness interrogation
• whether stronger documents can be gathered
• whether a different set of measures can be proposed

It is not advisable to respond immediately with the same type of letter. It is better to prepare a new motion only when something stronger can be presented: a document, an action taken, a change in situation, bail, or a new argument.

In detention cases, patience and consistency are important but must be accompanied by substance.

FAQ – motion to revoke pre-trial detention

What is a motion to revoke pre-trial detention?

It is a document in which the defense demands the termination of further detention. It may also include a request to change detention to milder measures, such as police supervision, bail, prohibition of contact, or prohibition of leaving the country.

When does a motion to revoke pre-trial detention make sense?

The motion makes sense when it can be demonstrated that further isolation is unnecessary. This may concern witness interrogation, securing evidence, lack of real flight risk, possibility of bail, health condition, or other new circumstances.

Are a motion to revoke detention and a complaint the same?

No. A complaint challenges a specific decision to apply or extend detention. A motion to revoke or change detention concerns the further application of the measure and may be filed later, especially when new circumstances arise.

Can a motion be filed without new circumstances?

It can, but such a motion is usually weaker. The greatest importance lies in new arguments or demonstrating that previous grounds for detention have lost validity. Repeating the same claims is rarely effective.

Can bail help to get out of detention?

It can help if the court finds that bail realistically secures the proper course of proceedings. Bail is often worth combining with other measures, such as police supervision, prohibition of leaving the country, or prohibition of contact with specific persons.

Can police supervision replace pre-trial detention?

Yes, in some cases police supervision can be an alternative to detention. However, it must be demonstrated that supervision is sufficient to secure the proceedings and that further isolation is not necessary.

Can the family draft a motion to revoke detention on their own?

The family can prepare documents and information, but the motion should be tailored to the case files, grounds for detention, and procedural situation. Therefore, in practice it is best if it is prepared or at least reviewed by a defence attorney.

What documents are needed for the motion?

Useful documents may include proof of employment, place of residence, family situation, health condition, child care, business activity, possibility of bail, and source of funds for the bail.

Can health condition be a basis for revoking detention?

It can be an important argument but must be well documented. Medical certificates, medical history, list of medications, hospitalisation records or other materials showing why further isolation is particularly problematic are required.

Can subsequent motions to revoke detention be filed?

Yes, but subsequent motions should contain new arguments. This may include witness testimonies, securing evidence, change in health condition, bail, or prolonged inactivity in the case.

What to do if the court refuses to revoke detention?

The reasoning for refusal should be analysed to identify which arguments the court found insufficient. Then further steps can be prepared: gather documents, wait for procedural actions, propose alternative measures, or respond to detention extension.

Does pre-trial detention mean conviction?

No. Pre-trial detention is not a verdict and does not mean a final conviction. It is a preventive measure applied during the proceedings. The detained person still has the right to defence.

Summary – when does a motion to revoke pre-trial detention make the most sense?

A motion to revoke pre-trial detention makes the most sense when based on specific arguments. It is not enough to state that the suspect wants to return home. It must be shown that further detention is unnecessary or that the proceedings can be secured by milder measures.

The key is to determine why the court applied detention. If it was due to fear of tampering, it must be shown that witnesses have been questioned, evidence secured, or that a contact ban suffices. If it was due to flight risk, proof of permanent residence, employment, family, ties to Poland and possibility of supervision must be shown. If the concern was a severe penalty, it must be demonstrated that the severity of the penalty alone does not justify further isolation without real risks.

A good motion should include:

• analysis of the grounds for detention
• indication of new circumstances
• arguments against continued isolation
• family, professional, and medical documents
• proposal of bail
• proposal of police supervision
• proposal of contact ban or travel ban
• explanation why milder measures suffice
• calm and factual language

The detained person’s family can be very helpful but must act prudently. It is best to gather documents, determine case number, court, prosecutor’s office, date and duration of detention, health, employment and possible bail information. However, chaotic contact with witnesses, deleting messages, publishing the case online or attempting to influence the victim is prohibited.

Pre-trial detention is very serious but does not close the door to defence. After detention is applied, complaints can be filed, motions to revoke or change the measure prepared, responses to detention extensions made, and new documents submitted. The most important is to act quickly, specifically and based on the case files, not solely on emotions.

If the case concerns detention after arrest, charges, detention hearing, complaint or motion to revoke pre-trial detention, it is advisable to seek assistance within criminal law and describe the situation via the page contact. In detention cases, time, documents and a well-prepared defence strategy matter.
