The central puropse of this thesis has been to provide a more profound understanding of the position of the State Attorney General in a criminal prosecution. For criminal offences prosecutable ex officio the authorized prosecutor is the State Attorney General and his powers are listed in Article 38 of the Criminal Procedure Act. Because of the recent amendments of the CPA (Criminal Procedure Act) that entered into force on 1 January 2009, the position of State Attorney General has considerably changed and his role has strengthened so it is understandable that, with law powers and duties pertaining to his office that have been extended, an indipendent operation is every stage of a proceeding is no longer possible. This is primarly related to his cooperation with the police department and investigator in a criminal prosecution. Besides being a master of the above mentioned proceeding, the State Attorney General shall institute the prosecution and represent the charge against perpetrators of criminal offences subject to public prosecution, and in relation to other subjects of a proceeding he is the only person authorized to file a request for the protection of legality as an extraordinary judicial remedy. This is especially expressed in his duty and role to represent the interests of the state and not the private interests of an individual in criminal prosecution.
