A superficial body search is admissible if that person
1. was arrested or caught in the act of committing a punishable act,
2. is suspected of a punishable act and it is to be expected, that he/she is carrying objects that are subject to seizure, or that he/she has traces with him/her,
3. might have suffered injuries which are due to a punishable act, or experienced other changes on his/her body, the determination of which is required for the purposes of criminal proceedings.
A physical examination is admissible if
1. it is to be assumed on the basis of certain facts that a person has left traces the seizure and investigation of which is of substantial value for the purpose of the investigation of a criminal offence,
2. it is to be assumed on the basis of certain facts that a person conceals objects in his/her body which are subject to seizure or
3. facts, which are of decisive importance for the investigation of a criminal offense or for the evaluation of the suspect's responsibility, can not otherwise be ascertained.
A physical examination is also admissible for persons belonging to a group of persons that can be individualized by certain characteristics, if it is to be assumed on the basis of certain facts that the perpetrator is part of this group of persons and the clearing up of a punishable act that carries a prison term of more than five years or of a punishable act against sexual integrity and sexual self determination (10th section of the Austrian Criminal Code) that carries a prison term of more than three years would otherwise be much more difficult.
In order to clear up a punishable offence, it is further possible to examine biological traces (DNA matching). Therefore, the public prosecutor's office entrusts an expert. For further information on how to appoint such expert please see measure A.43.
