If a party considers that its rights and legal interests have been violated by an individual decision, an administrative dispute may be initiated by the act of a public legal body or by failure to take an individual decision or act of a public legal body within the prescribed time limit or by concluding, terminating or enforcing an administrative contract. The same is considered to have been initiated on the day of the submission of the action to the competent court. The action shall be brought before the Court within 30 days of the notification of the contested individual decision or decision on the opposition to the contested action.
