In such cases, the presiding judge may permit the defendant to request a correction within a specified period even after the expiration of the period specified in Article 147 (1), if he or she deems it necessary to permit such request for correction because the petitioner has submitted any evidentiary document or asserts a new ground for invalidation. <Amended on Feb. 29, 2016>
