Life and health are goods protected by law. Due to the growing majority of public awareness, the risk of filing lawsuits by persons injured to court, or reports to the prosecutor’s office about the possibility of a crime by medical personnel, is increasing. The expert witness in the field of various medical specialties de facto takes the role of court, because the opinion is decisive and binding in the prosecution-court proceedings. In case of doubts you can ask for an opinion of another expert or for a supplementary opinion.

Key words: paramedic, system nurse, expert witness, medical error, abnormal treatment.
