Failure to report a crime

Glossary category

What is failure to report a crime?

Failure to report a crime means not notifying the competent authorities about information concerning an offence. In Polish law, this issue must be assessed carefully because not every failure to inform the police or prosecutor results in criminal liability.

A general social duty to report an offence is provided for in Article 304 of the Polish Code of Criminal Procedure. Anyone who becomes aware that a crime prosecuted ex officio may have been committed should notify the prosecutor or the police. For private individuals, however, this general duty usually has a civic rather than criminal-law character.

Criminal liability may arise in more serious cases. Article 240 of the Polish Criminal Code penalises a person who has credible information about the preparation, attempt or commission of certain particularly serious offences and fails to notify the authority responsible for prosecuting crimes without delay. The offence is commonly described as failure to report a crime, non-reporting of a crime, or failure to notify the authorities.


When can failure to report a crime lead to criminal liability?

Article 240 of the Polish Criminal Code applies only to offences expressly listed in that provision. They include, among others, crimes against peace and humanity, certain offences against the Republic of Poland, homicide, certain offences endangering public safety, terrorist offences, human trafficking and specified sexual offences, including certain rape offences, sexual abuse of a person in a relationship of dependence or in a critical situation, and sexual acts with a minor under 15.

The provision does not create a general obligation to report every suspected crime. For example, a person who does not report an ordinary theft, fraud or a civil property dispute will not normally be liable under Article 240 solely because of the lack of notification. The circumstances may nevertheless require analysis under other legal provisions, especially where the person has professional, contractual or official reporting duties.

For liability to arise, the information must be credible. Mere rumours, unverified online statements or vague suspicions are not automatically sufficient. At the same time, a person does not need to possess complete evidence or know every detail of the incident. What matters is whether the available information reasonably indicates that one of the offences covered by Article 240 may be planned, attempted or committed.


What does the duty to report involve?

The notification should be made without undue delay to an authority appointed to prosecute crimes, usually the police or the public prosecutor. In urgent situations, particularly where there is a risk to life, health or public safety, calling the emergency number may be the appropriate first step.

A report does not have to contain a full legal assessment of the events. The reporting person should communicate the facts known to them, identify persons involved where possible, indicate available evidence and explain why the matter may require immediate intervention. The authorities are responsible for determining whether a crime has occurred and whether criminal proceedings should be opened.

Under Article 240 of the Polish Criminal Code, failure to report a covered offence may be punishable by imprisonment for up to 3 years. The statutory penalty and the exact legal classification depend on the facts of the case and the version of the legislation in force at the relevant time.


Exceptions and protection of the reporting person

Polish law recognises that reporting an offence may place a person in a difficult personal position. A person does not commit the offence of failure to report where they have sufficient grounds to believe that the authority responsible for prosecuting crimes already knows about the planned, attempted or committed offence. A person who refrains from notification because of fear of criminal liability for themselves or a close relative is not subject to punishment. In addition, a person who prevents the planned or attempted offence from being committed is not subject to punishment for failing to notify the authorities.

These exceptions do not mean that every concern, inconvenience or reluctance to participate in proceedings removes the reporting duty. Whether an exception applies requires an individual assessment of the information held, the relationship between the persons involved, the risk of self-incrimination and the actions taken to prevent harm.


When is legal advice advisable?

Legal assistance may be important for a person who has learned about a potentially serious offence but is uncertain whether the information is sufficiently credible, whether Article 240 applies or how to notify the authorities safely. Advice may also be needed by a witness, employee, manager, family member or person who may be connected with the events under investigation.

A prompt consultation with a lawyer can help identify reporting obligations, protect the person’s procedural rights and reduce the risk of making inaccurate statements or misunderstanding legally significant duties. It may also be relevant where reporting could expose the person or a close relative to criminal liability.


Legal support in matters involving failure to report a crime may include:

  • assessing whether the circumstances fall within Article 240 of the Polish Criminal Code;
  • advising on the preparation of a notification to the police or prosecutor;
  • evaluating the credibility and legal relevance of available information;
  • representing witnesses and injured parties in criminal proceedings;
  • advising persons at risk of criminal liability or self-incrimination;
  • analysing reporting duties connected with employment, management or professional functions.
