Strict conditions apply to surveillance
Communications surveillance is a serious intrusion on privacy. That's why there are strict conditions for permitting communications surveillance. The police have to obtain a warrant from the court before they can start surveillance.
Communications surveillance is regulated by chapter 16a of the Criminal Procedure Act (link to lovdata.no).
Used in serious cases
Communications surveillance can only be used in the most serious cases. The most common are suspected serious drug offences or organised crime. There have to be reasonable grounds to believe that the suspect has committed such criminal offences. Tapping or surveillance must also be of key importance to solving the case, and solving it would be significantly harder without them.
Naturally, the suspect will not be notified when the police want communications surveillance. To protect the rights of the suspect, a lawyer is always appointed. A surveillance committee is also set up to control use by the police of communications surveillance.
The period for communications surveillance is normally set to 4 weeks.
