Public authorities may be granted secret surveillance powers over private telephone conversations, e-mail and postal mail. If you are suspected of having committed a crime or posing threats to national security, or are closely related to such a person, your communications may be subject to these techniques.

You can find the relevant legal provisions in the Code of Criminal Procedure and in the Law on Criminal Intelligence. Monitoring of private communications can be performed either in the form of: 

Special investigative actions

During special investigative actions, public authorities can apply control over and seizure of (postal) correspondence and monitoring of telephone conversations and other means of communication, such as e-mails and text messages in the course of criminal proceedings if:

  • there are reasonable grounds to believe that these communications could contain needed evidence, and 
  • only if there are no alternative means for obtaining the evidence

These actions are carried out without the knowledge of the persons concerned and must be sanctioned by the investigative judge.

Operational actions

During operational actions, the monitoring of postal, electronic and other types of correspondence, as well as the wiretapping of telephone, electronic conversations and other means of communications can be performed if:

  • there is well-founded information about the particular persons’ connection to a grave crime, for example, to state security, or
  • if a suspect or convicted person absconds, or a person goes missing.

Such actions are performed without the knowledge of the persons concerned and must be sanctioned by the regional court judge.

What human rights violation may there be?

Although the use of secret surveillance may be necessary in the interests of national security and/or for the prevention of disorder or crime, these actions interfere with your private life. However, only unlawful intrusion will result in the violation of your human right to private life.

Was the action carried out lawfully?

To evaluate whether an investigative or operational action against you was carried out lawfully and whether your privacy has been sufficiently respected, see the questions below. If, in your situation, your answer to one of these questions was negative, your privacy may have been violated. In such a case, you have the right to complain. Read more about how to complain.
