The Constitutional Court in Latvia safeguards the Satversme (Constitution) ensuring priority of the constitutional regulation. Justice at the Constitutional Court is administrated by solving disputes regarding compatibility of legal provisions with the provisions of higher legal force, which can be realized in a posteriori and also a priori form. As it is not allowed to initiate case ex officio, procedure at the Constitutional Court can be started by receiving application either from so called abstract persons, courts, local government councils and also persons who can submit constitutional complaints if a legal norm violates fundamental human rights of a submitter. Constitutional complaint cannot be abstract: person has to prove violation of fundamental human rights, principle of subsidiarity and term.
