The right to a legal remedy is a constitutional and legal right of citizens, but also a universal human right integrated into the legislation of all modern countries. Extraordinary legal remedies in administrative proceedings are special legal mechanisms available to parties in administrative cases to challenge administrative decisions or actions. These legal remedies provide an opportunity to review decisions made by administrative bodies when they are regular legal remedies. The Law on General Administrative Procedure regulates administrative procedures in Republic of Croatia, and in addition to other procedural issues, it also regulates extraordinary legal remedies that are available to parties dissatisfied with the outcome of the administrative procedure. Extraordinary legal remedies in the administrative procedure are renewal of the procedure, declaring the decision null and void, annulment and cancellation of the illegal decision. Also, the Law on Administrative Disputes regulates extraordinary legal remedies in an administrative dispute, namely the renewal of an administrative dispute and a request for an extraordinary review of the legality of a final judgment.
