Intelligence services and criminal proceedings
Criminal law risks arising from findings by the Federal Office for the Protection of the Constitution and the Federal Intelligence Service
For suspects, contact with intelligence services rarely begins with a summons or indictment. Often, the terms "Office for the Protection of the Constitution" or "Federal Intelligence Service" (BND) first appear in connection with a damaging (intrusive) measure – for example, during a search, a refusal of entry, or an immigration-related measure. It is not uncommon for a criminal assessment to follow intelligence surveillance only after a considerable delay.
Unlike traditional criminal offenses, this involves no specific accusation, but rather the use, disclosure, and re-evaluation of information originally collected for preventative purposes. It is precisely at this juncture that significant criminal risks arise – often without those affected, or later accused, having had the opportunity to comment or take legal action.
Intelligence agencies are not law enforcement agencies
Intelligence services such as the Federal Office for the Protection of the Constitution or the Federal Intelligence Service are not law enforcement agencies. Their task is to gather information for the purpose of preventing threats and assessing the political situation, not to investigate specific crimes. This institutional separation is mandated by the constitution. The so-called principle of separation is intended to prevent preventive surveillance and repressive law enforcement from becoming intertwined.
Intelligence findings are therefore subject to different requirements for their collection, different purposes, and different standards of evaluation than evidence in criminal proceedings. Problems arise when such findings are nevertheless passed on to law enforcement agencies and used as a basis for investigations.
How do intelligence findings find their way into criminal proceedings?
The disclosure of information by intelligence services is only permitted in legally regulated situations.
Data transmission by the BND and the Federal Office for the Protection of the Constitution
In particular, the Federal Intelligence Service Act (BND Act) and other specific legal regulations permit the transfer of personal data to law enforcement agencies under strict conditions. A prerequisite is generally that the information obtained could be relevant for the prosecution of particularly serious crimes.
Furthermore, the principle of purpose limitation applies: data collected for preventive purposes may not be used for repressive purposes without further ado. Any change of purpose constitutes an independent infringement of fundamental rights and requires a clear legal basis.
The Federal Constitutional Court has ruled in several decisions that data exchange between intelligence services and law enforcement agencies is subject to strict requirements. Blanket or indiscriminate transfers are inadmissible.
Typical criminal charges related to intelligence services
Even though intelligence services do not conduct criminal investigations themselves, certain criminal offenses appear particularly frequently following intelligence findings.
Organizational and state security offenses
A classic starting point is investigations into:
- the charge of forming or supporting a terrorist organization (§§ 129a, 129b StGB),
- other organization-related offenses.
Even loose contacts, communication relationships, or ideological affinity can be classified as "relevant" by intelligence services, without the need to meet the legal requirements for membership or support. In these cases, there is regularly a significant tension between intelligence assessments of potential threats and the suspicion of a crime under criminal procedure.
Political speech offenses
Intelligence services regularly collect publicly available statements, such as:
- Social media posts,
- Speeches or slogans at demonstrations,
- Publications or interviews.
This content is often later re-evaluated under criminal law, for example under the aspects of Sections 86, 86a, 130, 140 or 188 of the German Criminal Code (StGB). In doing so, there is a risk of loss of context: What intelligence services interpreted as an indication of an "anti-constitutional endeavor" is often insufficient for a conviction under criminal law.
Preparatory acts and preliminary offenses
Criminal offenses with a pre-emptive threat approach – such as those involving the financing of terrorism or preparatory acts – also play a role in the intelligence service context. Here, in particular, the distinction between political, religious, or ideological activity and criminal behavior is especially sensitive.
Constitutional limits on data exchange
In several landmark decisions, the Federal Constitutional Court has clarified the constitutional limits of data exchange between intelligence services and law enforcement agencies. This jurisprudence is of central importance for the practice of criminal defense.
Purpose limitation and informational separation principle:
BVerfG, decision of. September 28, 2022 – 1 BvR 2354/13, NStZ-RR 2023, 17:
According to the jurisprudence of the Federal Constitutional Court, the transfer of personal data by domestic intelligence agencies is subject to strict requirements. Disclosure is only permissible if it is based on a clear legal foundation and the new purpose is sufficiently defined. Mere abstract precautionary measures are insufficient.
At the same time, the Federal Constitutional Court emphasizes the so-called informational separation principle: Data collected preventively may not be used repressively without further ado. Any change of purpose constitutes an independent infringement of fundamental rights and requires separate justification.
Anti-terror database and data mining:
Federal Constitutional Court, Judgment of 24 April 2013 – 1 BvR 1215/07, NJW 2013, 1499:
In its ruling on the anti-terrorism database, the Federal Constitutional Court clarified that interagency data sharing between police and intelligence services is only permissible under strict conditions. In particular, the depth of data, access rights, and evaluation powers must be clearly limited. Blanket or indiscriminate merging of personal data is inadmissible.
The court has also applied these standards to modern forms of data mining. Automated data analyses must not lead to the "extrapolation" of criminally relevant suspicions from mere contact or communication data.
Signals intelligence by the BND:
Federal Constitutional Court, Decision of 10 November 2020 – 1 BvR 3214/15, NVwZ 2021, 226;
Federal Constitutional Court, Judgment of 19 May 2020 – 1 BvR 2835/17, NJW 2020, 2235.
The Federal Constitutional Court's decision regarding the Federal Intelligence Service's (BND) foreign-to-foreign telecommunications surveillance is of particular importance. The court clarified that the BND, even in its strategic telecommunications surveillance activities, is fully bound by fundamental rights. This applies especially to the confidentiality of telecommunications and the protection of personal data. Information obtained through such measures may not be used without restriction in criminal proceedings.
Admissibility in criminal proceedings
Not all information obtained lawfully is admissible in criminal proceedings. The inclusion of intelligence findings in criminal proceedings requires that...
- the transfer was lawful,
- a legal authorization to use exists,
- the measure is proportionate,
- The rights of the accused are preserved.
Errors in data transmission, changes of purpose or documentation can lead to prohibitions on the use of evidence or call into question the initial suspicion altogether.
Non-criminal consequences: residence, occupation, status
The consequences of intelligence findings outside of criminal law are particularly far-reaching.
Right of residence
Intelligence assessments can form the basis for:
- the refusal or revocation of a residence permit,
- the refusal of a residence permit,
- Deportation decisions
to be – sometimes without a criminal conviction. The standards of proof in immigration law are lower than in criminal proceedings. This makes early coordination of the defense between criminal and administrative law all the more important.
Civil service and professional law
Intelligence findings can also have serious consequences in the public sector or in security-relevant activities:
- Disciplinary proceedings,
- Dismissal from service,
- Refusal of security checks,
- Revocation of firearms licenses.
Here, even the suspicion of anti-constitutional activity has a lasting impact.
Defense strategies in cases involving intelligence services
An effective defense starts early and considers several levels:
- precise analysis of the origin of the findings,
- Review of the transmission and purpose limitation rules,
- Attack on the initial suspicion in criminal proceedings,
- Contextualizing political or ideological statements,
- Examination of admissibility in criminal proceedings,
- If necessary, coordination with immigration or employment law procedures.
Precisely because those affected, or subsequently accused, often only learn about the intelligence service's involvement at a late stage, a strategic defense is crucial.
What does this mean for suspects or defendants?
In proceedings involving security authorities, criminal defense is of particular importance. It is often impossible for defendants to discern which assumptions, indications, or assessments are actually shaping the proceedings. The real conflict then takes place not openly in court, but covertly during the investigation phase.
Criminal defense in this context primarily means establishing transparency, critically examining investigative approaches, and insisting that only verifiable facts form the basis of the proceedings. The aim is to break down a security-driven bias and return criminal proceedings to their core principles of the rule of law.
Especially in such situations, early defense determines whether a procedure is limited in scope or escalated in terms of security policy.
FAQ – Intelligence Services and Criminal Proceedings
Am I a suspect simply because the Federal Office for the Protection of the Constitution or the Federal Intelligence Service collects information about me?
No. Intelligence surveillance alone does not constitute grounds for criminal suspicion. Intelligence services operate preventively, not repressively. However, under certain circumstances, their findings can be shared with law enforcement agencies and trigger investigations.
Are intelligence agencies allowed to pass on my personal data to the public prosecutor's office?
The disclosure of personal data by intelligence services is only permissible under strict legal conditions. A connection to particularly serious crimes and a clear legal authorization for the transfer are generally required. Blanket or indiscriminate data transfers are inadmissible.
Are intelligence findings automatically admissible in criminal proceedings?
No. Even lawfully obtained intelligence is not automatically admissible in criminal proceedings. It requires a permissible change of purpose and an independent authorization for its use. Errors can lead to the exclusion of evidence.
Is it possible for my home to be searched even though I was never questioned by the police?
Yes. In practice, it sometimes happens that investigative authorities order coercive measures at an early stage based on information provided to them.
What role does freedom of expression play in statements monitored by intelligence services?
Political statements are afforded the special protection of freedom of expression under Article 5 of the Basic Law. Intelligence assessments do not replace a criminal investigation. Statements may not be criminalized solely because of their political or ideological orientation.
Which criminal charges are particularly common in connection with intelligence services?
In practice, these cases often involve organizational and state security offenses, political freedom of expression, or preliminary offenses. However, not every intelligence classification constitutes a legally valid criminal charge.
What consequences do non-Germans face if they have dealings with intelligence services?
In addition to criminal proceedings, immigration-related measures may be imposed, such as the revocation or non-renewal of a residence permit. These decisions can sometimes be made independently of the outcome of the criminal proceedings.
Can intelligence findings have professional consequences?
Yes. Particularly in the public sector or in security-relevant activities, intelligence findings can lead to disciplinary measures, failure to pass a security clearance, or other consequences regarding one's legal status.
Should I provide information to the police or public prosecutor's office if intelligence services are mentioned?
No statements should be made in such criminal proceedings without prior legal advice. Especially when intelligence services are involved, it is crucial to first examine the case file, the source of the information, and its legal admissibility.
When should a criminal defense lawyer be involved if intelligence services are involved?
As early as possible. The earlier the defense begins, the better criminal and extra-criminal risks can be limited and strategic decisions made.
