[National and international aspects of the medico-legal examination of injured witnesses and defendants in criminal proceedings].

Depending on the type of offence, the medico-legal examination of victims of violence for the purpose of collecting evidence in criminal proceedings requires prompt physical examination of the victim, the exact description and, wherever possible, photographic documentation of the injuries and their forensically correct interpretation. Examination, documentation and assessment have to meet minimum standards. In addition it must be ensured that the examiner or expert has an independent organisational, administrative and financial status. An independent expert must not be an organisational part of the police force, the public prosecution and the court. Legal regulations have to make sure that the expert cannot be influenced "through official channels". His or her financial independence must make attempted bribery at least improbable. The independence of the expert is particularly important, if persons become victims of violence while they are under the custody of the state, especially the police, in prisons and after compulsory commitment to a psychiatric hospital.
