The organic law acts as a Municipal Constitution, being considered the most important law governing municipalities and the Federal District.
Each Brazilian municipality may determine its own organic laws, as long as these do not infringe the constitution and federal and state laws.
In this case, the approval of an organic law must be made by a majority of the members of the City Council (two thirds, at least), and the votes are divided into two rounds, with intervals of ten days between each.
After the approval of the organic law, it is up to the mayor of the municipality to ensure that it is complied with, always under the supervision of the City Council.
From a general point of view, organic laws are also present in other bodies and institutions public services, such as the Public Ministry, Social Security, Social Assistance, Public Security and etc.
In these cases, it is understood as an organic law that has an importance that lies between that of the ordinary and constitutional law, and should be deeply studied and analyzed before being voted on, as it presents rigidity in its regulation, and its alteration after approval is very difficult.
In Brazil, Complementary Law No. 35, of March 14, 1979, is responsible for disposing of the organic laws of the National Magistracy.
