The Regional Parliament is a decision-making and control body of the regional government. It is composed of 39 members chosen in direct elections held every 5 years. As a decision-making body, the Regional Parliament implements tasks specified in legal acts. Its decisions are made during sessions in the form of resolutions. The resolutions of the Regional Parliament are passed by a simple majority of votes, in the presence of at least half of the Regional Parliament, in an open or open roll-call ballot, unless provided otherwise by legal acts. It performs its control functions through the control rights of the Audit Committee and other standing committees, as well as through interpellations and other members' inquiries.

The members of the Regional Parliament elect a President from among their ranks, who is responsible for the organisation of the Parliament's work and presides over debates – sessions.
