The legislative process is led either by the Assembly of the Republic, by the Government or by the legislative assemblies of the autonomous regions, depending on the matter to be legislated and the corresponding respective competence of each body.
The process of creation of regional legislative decrees is analogous to those of creation of laws, but with the participation of the regional bodies of self-government (legislative assemblies, regional governments and representatives of the Republic), instead of the direct participation of the national bodies.
