However, on 1 September 2000, A.M. No. 00-2-03-SC took effect amending Section 4, Rule 65 of the 1997 Rules of Civil Procedure whereby the 60-day period within which to file the petition starts to run from receipt of notice of the denial of the motion for reconsideration, if one is filed. This Court has in several cases[10]ruled that A.M. No. 00-2-03-SC, being a curative statute, should be applied retroactively. In the case of Narzoles v. NLRC, we explained the rationale for this retroactive application:   The Court has observed that Circular No. 39-98 has generated tremendous confusion resulting in the dismissal of numerous cases for late filing. This may have been because, historically, i.e., even before the 1997 revision to the Rules of Civil Procedure, a party had a fresh period from receipt of the order denying the motion for reconsideration to file a petition for certiorari. Were it not for the amendments brought about by Circular No. 39-98, the cases so dismissed would have been resolved on the merits. Hence, the Court deemed it wise to revert to the old rule allowing a party a fresh 60-day period from notice of the denial of the motion for reconsideration to file a petition for certiorari. Earlier this year, the Court resolved, in A.M. No. 00-2-03-SC, to further amend Section 4, Rule 65 to read as follows:     Sec. 4.   When and where petition filed. The petition shall be filed not later than sixty (60) days from notice of the judgment, order or resolution. In case a motion for reconsideration or new trial is timely filed, whether such motion is required or not, the sixty (60) day period shall be counted from notice of the denial of said motion.   The petition shall be filed in the Supreme Court or, if it relates to the acts or omissions of a lower court or of a corporation, board, officer or person, in the Regional Trial Court exercising jurisdiction over the territorial area as defined by the Supreme Court. It may also be filed in the Court of Appeals whether or not the same is in aid of its appellate jurisdiction or in the Sandiganbayan if it is in aid of its appellate jurisdiction. If it involves the acts or omissions of a quasi-judicial agency, unless otherwise provided by law or these rules, the petition shall be filed in and cognizable only by the Court of Appeals.   No extension of time to file the petition shall be granted except for compelling reason and in no case exceeding fifteen (15) days.
