The organisation of the Greek Penitentiary System is based on general principles drawn from the Constitution, the international conventions, the laws, and the presidential decrees as well as the legislative acts authorised by them, using as legal basis the effective Penitentiary Code.
The general principles are concerned with the rules of penalty executions and security measures against freedom, as are stated by the competents tribunals, and the treatment of prisoners into the prisons.
Inviolable principles in the application of the above rules constitute the treatment of prisoners equally and legally, the respect for their law-given rights, and their legal protection. In the above Penitentiary Code are discribed all the organs exercising the penitentiary policy like: the Central Scientific Prison Council, the Central Council for Prisoners Transfer and the Council of every Prison.
They are also defermined the different categories of prisons and prisoners, the conditions of living in prison and tranfer, the application of programs and the use of the prisoners` free time, their work, the benefician calculation of days of sentence because and if they work and the communication with the social environment.
The same Code describes, too, the alternate ways of serving sentences, the measures taken for the correct operation of the prisons, the procedure for transferring prisoners, the ways of terminating sentences, post-penitentiary care, the supervision of the Code's application and its enforcers.
