Local and regional self-government is a common name for various organized ways in which the citizens of the local community, at their own risk, relatively independently regulate certain public affairs and manage them. There is currently no single election law in the Republic of Croatia, which would prescribe the basic principles and institutes common to all election procedures, but each type of election is prescribed by a special law. When it comes to regular elections, regular elections for members of the representative bodies of local and regional self-government units are held every fourth year, on the third Sunday in May. It is important for the conduct of elections that the Constitutional Court of the Republic of Croatia monitors the constitutionality and legality of elections for members of representative bodies of local and regional self-government units and resolves election disputes in accordance with the provisions of the Local Elections Act. The Municipality of Lopar is independent in deciding on matters within its self-governing scope in accordance with the Constitution of the Republic of Croatia and the Act and is subject to the supervision of the constitutionality and legality of authorized state bodies. In the Municipality of Lopar, in 2017, elections were held for a representative of the self-government, ie for the mayor of the Municipality of Lopar.
