Expert Opinion and Evidence in Criminal Proceedings

Abstract

Expert opinion and evidence is a new kind of evidence in criminal proceedings. There are still a lot of gaps regarding the expert’s opinion in law and in practice. The expert invited by the defender for the criminal case study, conducts a short survey using portable equipment, if it does not damage the materials under study. This requires the judge’s permission. Polygraph testing is carried out by a specialist. The expert can check everything that is available for public inspection: streets, buildings, countryside. The defender can announce in court the information obtained on the expert’s advice.
