If the Court of Appeals determines from the petition, from any hearing on the petition, from a review of the records of the case, or from any response from the Attorney General that a resolution of the case requires further development of the facts, the court may order the circuit court in which the order of conviction or the adjudication of delinquency was originally entered to conduct a hearing within 90 days after the order has been issued to certify findings of fact with respect to such issues as the Court of Appeals shall direct. The record and certified findings of fact of the circuit court shall be filed in the Court of Appeals within 30 days after the hearing is concluded. The petitioner or his attorney of record, the attorney for the Commonwealth and the Attorney General shall be served a copy of the order stating the specific purpose and evidence for which the hearing has been ordered.
