Statistics

The Swiss prosecution authorities and the Federal intelligence service (FIS) may order post and telecommunications surveillance measures for the purpose of investigating serious criminal offences based on the Swiss Criminal Procedure Code and the Federal Intelligence Service Act.

According to the figures and a comparison with the total number of offences committed (2019: 544,781), telecommunications surveillance is used in about 1.5% of all offences.

The overall number of surveillance measures ordered has steadily increased in 2019 to a total of 8,666 (7,558 the previous year). The increase of retroactive surveillance measures is due to the increase of Antenna search measures and to technical reasons. The new Warrant Management Component (WMC) was introduced on March 23, 2019 with which antenna searches now can be statistically recorded and reported in greater detail.

In 2019, approximately 40% of these surveillance measures were ordered by prosecution authorities or the FIS for the purpose of investigating serious offences against property; 26% concerned serious offences against the Narcotics Act, and 10% for offences against life and limb. The remainder related to other types of offences, including felonies and crimes against liberty and offences against sexual integrity.

The Articles 269bis and 269ter of the Swiss Criminal Procedure Code allow the use of special technical devices (IMSI catchers) and computer software (govware) for telecommunications surveillance. 
In 2019, 12 operations used this special computer software. The number of operations using special technical devices (IMSI-Catcher) amounts to 103 compared to 84 in the previous year.

Note: In connection with the revision of the Federal Act on Post and Telecommunications Surveillance (BÜPF/APTS), the Post and Telecommunications Surveillance Service (PTSS) introduced a more detailed method for counting statistical data (for more information on the new counting method, please refer to this press release). For this reason, a comparison of recent years is only possible to a certain extent. Furthermore the numbers presented by FIS and those by the PTSS are not comparable due to a different counting method.

See the detailed statistics 2011-2019 under Publications.
