Constitutional Court Procedure Act Article 32

(General Rules on Vote Threshold for Admissibility)Any inadmissible or manifestly unfounded petition shall be dismissed by an order of the Constitutional Court.Except otherwise provided in this Act, an order that grants admission to a petition requires the consent of a majority of the Justices who have taken part in the proceedings with a quorum of two-thirds of the total number of the incumbent Justices of the Constitutional Court taking part in the proceedings. Failing the required majority, the petition shall be dismissed by an order.A dismissal order must give reasons and indicate the names of Justices taking part in the rendering of the order and their concurring or dissenting opinions where applicable.
