Concept and definition of the agent provocateur
An agent provocateur is a person who, at the behest of law enforcement agencies, deliberately incites, prepares, or assists in the committing of crimes in order to induce others to commit an offense, with the aim of uncovering their criminal actions and subjecting those involved to prosecution. The activity of an agent provocateur is particularly relevant in the context of undercover investigations and the work of police and prosecutors. The use of agent provocateurs is discussed both in German and international criminal procedure law, as their deployment raises profound legal and ethical issues.
Legal classification of the agent provocateur
Distinction from similar terms
Undercover investigator
Unlike the agent provocateur, the undercover investigator is an officer deployed to solve crimes without inducing the targeted person to commit an offense. The agent provocateur, by contrast, is often a private individual or non-officer who actively contributes to the commission of a crime.
Informant
An informant merely obtains information about crimes that have already been planned or committed. However, unlike the classic agent provocateur, he does not play an instigating or provocative role.
Legal perspective on the use of agent provocateurs in Germany
Legal basis
Neither the term nor the deployment of agent provocateurs is explicitly regulated by law in Germany. Their use arises from police practice and is based on measures under the police laws of the federal states or the Code of Criminal Procedure (StPO), in particular in the context of undercover investigations (§§ 110a ff. StPO). The case law of the Federal Court of Justice (BGH) and the Federal Constitutional Court plays a decisive role in shaping the admissibility and limits of the use of agent provocateurs.
Requirements and limits
Central to this is the distinction between ‘passive law enforcement’ and impermissible act provocation. While the mere offer to investigate an already planned or ongoing crime is considered legitimate, the deliberate provocation of a person to commit an offense for the first time is impermissible.
Act provocation
Act provocation refers to the deliberate inducement to commit a crime that the target person would not have committed without the intervention of the agent provocateur. The courts are critical of such measures. According to established supreme court jurisprudence (e.g., BGH, decision of 10.01.1991 – BGHSt 37, 74), act provocation may lead to the exclusion of evidence or at least to a mitigation of sentence due to a violation of the principle of a fair trial (Art. 6(1) ECHR).
Proportionality and the rule of law principle
The deployment of an agent provocateur is subject to the requirements of proportionality and the principle of legality in administration. The measure must be suitable, necessary, and reasonable. Disproportionate intervention or exceeding the permissible role results in the illegality of the action.
Relevance under criminal law
The behavior of an agent provocateur may itself meet the elements of a criminal offense, such as incitement (§ 26 StGB) or aiding and abetting (§ 27 StGB). However, criminal liability is usually excluded by virtue of acting on behalf of law enforcement authorities.
Legal consequences: Mitigation of sentence, dismissal, or acquittal
If impermissible act provocation is demonstrated, the courts may mitigate the sentence, dismiss the proceedings, or—in cases of serious violations of the fair trial principle—acquit the defendant.
Agent provocateur in international law
European Convention on Human Rights (ECHR)
Art. 6 ECHR guarantees the right to a fair trial and sets a central limit on the use of agent provocateurs. The European Court of Human Rights (ECtHR) requires careful scrutiny and, if necessary, clarification of the facts in criminal proceedings to prevent abuse and arbitrary prosecution through act provocation.
Comparable legal systems
In the United States (keyword: ‘Entrapment’) and the United Kingdom, there are similarly intense legal discussions about the ‘agent provocateur’. Particular emphasis is placed on ensuring that no innocent person is induced by state action to break the law.
Case law and practice
Key decisions
- Federal Court of Justice, decision of 10.01.1991 (BGHSt 37, 74): Detailed determination of act provocation and requirements for proportionality.
- Federal Constitutional Court, decision of 09.06.2004 (2 BvR 974/01): Clarification of the requirements for the use of evidence and the mandate for fair proceedings.
- European Court of Human Rights, judgment of 21.02.2002 (Üçtaş v. Turkey): Landmark decision on the admissibility of state provocateurs.
Police practice
Agent provocateurs are used in particular in the areas of organized crime, drug enforcement, and anti-corruption. In practice, their cooperation is usually closely coordinated with measures involving undercover investigators.
Critical assessment and reform debate
Opportunities and risks
The use of agent provocateurs can make a valuable contribution to solving crimes that are difficult to investigate. This is contrasted by the risk of violating the rule of law and creating artificial criminality (the so-called ‘agents’ trap’).
Proposals for reform
There are repeated calls for explicit statutory regulation of the use of agent provocateurs, for clear procedural standards, strict controls, and improved legal protection for those affected.

Frequently asked questions
Is the use of agent provocateurs legally permissible in Germany?
The use of agent provocateurs, that is, persons who provoke or enable crimes with governmental approval or support, is only permissible under German law under very strict conditions. As a matter of principle, the targeted provocation of crimes is problematic as it conflicts with the tenets of the rule of law, particularly the prohibition of act provocation. Criminal proceedings based on crimes initiated by agent provocateurs may fail on legal grounds if the courts find unacceptable act provocation. The European Court of Human Rights (ECtHR) and the Federal Court of Justice (BGH) have repeatedly emphasized that the active inducement to commit an offense by state bodies or their helpers violates the right to a fair trial under Art. 6(1) ECHR and endangers the fairness of proceedings. The legal basis for the deployment of such persons is found only in specific statutory provisions, such as the Narcotics Act (BtMG) with the figure of the ‘trusted person’. However, this requires strict control and approval by the public prosecutor and is recognized by case law only in the field of organized crime and under stringent conditions.
What legal boundaries apply to the behavior of an agent provocateur?
Agent provocateurs are not permitted to act without limits. The prohibition of provocation is particularly significant in legal terms: it is impermissible for an agent provocateur to deliberately induce a suspect to commit a crime that the latter would not have committed without the agent provocateur’s influence. This applies especially in cases where there is no concrete suspicion of a crime. The boundary is crossed when the agent provocateur acts as the actual initiator of the offense. In such cases, there may be an absolute procedural impediment that can lead to the exclusion of evidence and even to the discontinuation of criminal proceedings. Agent provocateurs may only reveal an existing criminal inclination, not create or exacerbate it themselves.
What are the consequences of unlawful act provocation by an agent provocateur?
If there has been unlawful act provocation by an agent provocateur, this can have significant consequences for the criminal proceedings. On the one hand, any statement or other evidence obtained through the agent provocateur may be deemed inadmissible and therefore not be used to the defendant’s detriment. On the other hand, the entire criminal trial may be deemed unfair, so that the case may be dismissed, the defendant acquitted, or the sentence mitigated. The Federal Court of Justice distinguishes depending on the intensity of the provocation and the degree of state influence on the accused. In cases of extreme act provocation, the courts have even required that prosecution be completely dropped.
Who authorizes and monitors the use of agent provocateurs in investigations?
The use of agent provocateurs in Germany generally requires authorization and is subject to judicial and administrative oversight. For covert investigative measures such as the deployment of agent provocateurs, prior approval by the public prosecutor’s office is required and sometimes even a court order. The exact procedure depends on the respective state or federal law, particularly in the Police Act or the BtMG. The strictness of the control mechanisms is intended to minimize the risk of abuse or undue interference with investigations as much as possible. After the measure has ended, subsequent judicial review is provided for by including the matter in the records and, if applicable, notifying the accused.
What role does the European Court of Human Rights (ECtHR) play in the context of agent provocateurs?
The ECtHR has significantly shaped the topic of ‘state act provocation’ with its case law. In several judgments, the Court has made it clear that the deliberate incitement to commit a crime by state actors—which includes agent provocateurs—violates the right to a fair trial under Art. 6(1) ECHR. States are therefore required to establish measures to prevent impermissible act provocation and to ensure transparency and adequate control mechanisms. Courts in Germany are obliged to observe the requirements of the ECtHR and take them into account in their decisions, meaning that German courts are regularly required to thoroughly examine and assess the issue of act provocation.
Can evidence obtained by agent provocateurs be used in German criminal proceedings?
The admissibility of evidence obtained by agent provocateurs in criminal proceedings depends mainly on whether the agent provocateur acted within legal limits and no impermissible act provocation occurred. If the suspect was merely assisted by the agent provocateur in realizing an already existing criminal intent, the evidence is generally admissible. However, if agent provocateurs provoked the crime or induced the suspect to act, evidence is often inadmissible. The decision on admissibility is made by the competent court following a comprehensive assessment of the individual circumstances.
Are there special regulations for the use of agent provocateurs in organized crime?
Yes, there are sometimes specific legal regulations for the area of organized crime which allow and govern the use of agent provocateurs. For example, § 110a StPO or the Narcotics Act expressly provide for the undercover investigator and distinguish them from agent provocateurs. The order is subject to particularly high requirements and is only permissible if other investigative measures have no prospect of success or would be substantially more difficult. Here too, the strict prohibition of act provocation and the necessity of administrative or judicial oversight apply. The special statutory regulations take into account the particular dangers posed by organized structures, in order to enable effective law enforcement and balance this against the protection of defendants’ rights.
