Centres for young offenders The LORPM distinguishes between the offenses committed by persons under the age of 14 and those committed between the ages of 14 and 18. Royal Decree 1774/2004, of 30 July, develops the general statutory framework of centres for young offenders. It befalls the autonomous communities and cities to apply the measures imposed upon young offenders by the courts 156 383. The current Criminal Code, which dates from 1995, specifies that the minimum legal age for imprisonment is eighteen and informed the enactment of independent legislation to expressly regulate the criminal liability of those under that age. In compliance with that legal mandate, Public General Act 5/2000, of 12 January, was passed to regulate the criminal liability of juveniles (LORPM), which distinguishes between the offenses committed by persons over the age of 14 and under the age of 18, and those committed by persons under the age of 14. In the former case, it provides for what are referred to as “young offender centres”, designed not for serving “sentences” in the technical­ legal sense, but instead for applying what are referred to as certain “measures” of detention and of other kinds. If “sentences” and “measures” coincide for the purpose of reinsertion mentioned in article 25 of the Spanish Constitution, the “minor’s greater interest” is the specific purpose of the so-called “measures” within the sphere of young offenders. Royal Decree 1774/2004, of 30 July, approved the Regulations of the Public General Act governing the Criminal Liability of Juveniles, which develops the general statutory framework of centres for young offenders. The application of the measures imposed by the juvenile courts befalls the autonomous communities and cities, pursuant to article 45 of the LORPM, which in practice means a wide diversity not only in the public authorities with powers in the matter, but also, and this is more important, in management systems. The authorities in the autonomous communities may create centres for young offenders, but they may also enter into agreements with public or non-profit organisations (art. 45.3 LORPM) for the application of the measures in public or private centres. Nevertheless, in those cases of private management there is no conveyance of the powers in matters involving young offenders and supervisory powers are to be retained under all circumstances. The application of the measures regarding offences falling within the jurisdiction of the High Court (Audiencia Nacional) corresponds to the THE OMBUDSMAN OF SPAIN
