Constitutional Court Procedure Act Article 54

(Effect of Voidance with Time Limits on Pending Cases before Other Courts)In a judgment where a time period is set for the impugned statutory law to lapse, all courts shall, before the set time period expires, continue to apply the impugned statutory law to adjudicate cases, except otherwise declared in the holding of the said judgment. Notwithstanding, after balancing the protection of human rights and public interest, and out of necessity, the court may, on its own motion or the party's, suspend the proceedings by an order, and, upon the amendment of the impugned statutory law, resume the proceedings and adjudicate such cases in accordance with the amended law.An order denying the motion under the preceding Paragraph is subject to interlocutory appeals.
