Under the Greek Code of Criminal Procedure, offences committed by minors are judged by courts specially constituted for this purpose. These can be composed of a single judge, or three judges in the case of offences that would be deemed felonies had they been committed by an adult person. According to the Penal Code, Minors Courts do not impose sentences, but only reformative or therapeutic measures. In exceptional circumstances, they may impose temporary detention in a specialised facility to minors between the ages of 15 and 18.
