Outside criminal proceedings, the competent authority may order surveillance of post and telecommunications in order to find a missing person.
A person is considered missing if the following conditions are met:
his or her whereabouts are unknown or disproportionately difficult to determine; and
there are serious indications that his or her health or life are in grave danger.
The competent authority may employ technical equipment in accordance with Article 269bisCrimPC1, provided the previous measures for telecommunications surveillance pursuant to Art. 269 CrimPC have been unsuccessful, or a search using these measures would be futile or disproportionately difficult. It shall produce statistics on surveillance in accordance with Art. 269bisCrimPC.
The competent authority may also inspect data on third parties where this appears necessary in the circumstances in order to find the missing person.
