Thus the Romanian legislator showed in the exposition of the reasons in the Project of the local public administration law from 1991, that he had taken into consideration the administrative experience acquired until the end of the third decade: laws from 1952, 1929 and 1936 and the elements of comparative law in the outlining of the local public administration organization.
