This petition for review seeks to set aside the decision of the Court of Appeals, dated October 28, 1994, in CA-G.R. SP No. 31816. The challenged decision annulled and set aside the orders of the Regional Trial Court, Himamaylan, Negros Occidental, Branch 55, dated June 2, 1993 and July 19, 1993, for having been issued with grave abuse of discretion amounting to lack or excess of jurisdiction. Petitioner PCIBank likewise assails the subsequent resolution denying its motion for reconsideration.

The factual antecedents of this case are as follows:

On July 30 1979, herein private respondents, Segundo and Febe Maravilla, filed Civil Case No. 1221 for damages in the Regional Trial Court of Himamaylan, Negros Occidental against PCIBank. On December 29, 1987, said spouses were able to secure a favorable judgment and the trial court ordered PCIBank, to pay them P326,470.38 plus interest thereon as actual damages, P50,000.00 as moral damages, P20,000.00 as exemplary damages, and to pay the costs of suit. PCIBank seasonably appealed the trial court's judgment to the appellate court in CA-G.R. CV No. 17467, but on December 20, 1989 the Court of Appeals affirmed in toto the judgment appealed from.

PCIBank then filed a petition for review on certiorari with this Court. But the petition, docketed as G.R. No. L-91689, was dismissed for having been filed out of time. The trial court's judgment then became final and executory. The enforcement of the judgment, however, was stalled because PCIBank refused to pay the 12% per annum interest rate imposed by the trial court. PCIBank insisted that it was liable only for 6% annual interest. To resolve this conflict, the lower court, in its order dated February 6, 1991, reduced the computed interest to 6% per annum. The Maravillas moved for reconsideration of this order, but their motion was denied. They appealed the lower court's order to the Court of Appeals in CA-G.R. CV No. 32983. On May 29, 1992, the appellate court decided the appeal in their favor, disposing as follows:

PCIBank then filed with the trial court a Motion for Clarification and/or Recomputation" of the sum owing to the Maravilla spouses. The bank insisted that as per its computations, it owed the spouses P411,401.67,2 [Id. at 36.] insisting that the 12% interest provided for in the fallo of the decision in CA-G.R. CV No. 32983 should not be compounded since the decision did not provide for the same. The couple, however, in their comment on the said motion, submitted their own computations, showing that as of January 29, 1993, the principal owing them plus the 12% annual interest on said principal already amounted to P818,259.90 to which should be added the sum of P121,102.85 representing the total interest of 12% on yearly interest on principal amounts or a total of P939,362.75.3 [Id. at 33.]

On June 2, 1993, the trial court issued an order stating that the remaining liability of PCIBank to the Maravillas totaled P437,726.60, as of May 31, 1993.4 [Id. at 38.] In compliance with this order, PCIBank tendered to the lower court the sum of P437,726.60. The couple moved for reconsideration of said order. On June 28, 1993, they moved to withdraw the deposit, expressly reserving, however, their right to appeal should their motion for reconsideration be denied. On July 19, 1993, the trial court denied said motion for failure of the motion to contain a notice of hearing and declared its order of June 2, 1993 final and executory.

On August 12, 1993, the Maravilla spouses filed a special civil action for certiorari with the Court of Appeals, docketed as CA-G.R. SP No. 31816. They alleged that in issuing the questioned order of July 19, 1993, the trial court acted with grave abuse of discretion amounting to want of jurisdiction since it deprived them of recourse to the more convenient and inexpensive remedy of appeal.

On October 28, 1994, the appellate court disposed of CA-G.R. SP No. 31816 as follows:

On December 15, 1994, PCIBank moved for reconsideration, but the appellate court denied said motion.

Hence, the instant case. Petitioner PCIBank now avers as grounds for allowance of its petition the following alleged errors:

Petitioner submits that the first two foregoing grounds are interrelated and should be discussed jointly.

Briefly, we find that the issues for our resolution are: (1) Did the appellate court commit a reversible error of law in granting the writ of certiorari? and (2) Did said court err in amending its decision which had already become final and executory?

To resolve the issue of whether the writ of certiorari was proper, we must consider whether or not the trial court gravely abused its discretion in denying private respondents' motion for reconsideration of its order dated June 2, 1993. For certiorari to lie, it must be shown that the tribunal, board, or officer exercising judicial functions acted without or in excess of jurisdiction or with grave discretion amounting to lack or excess of jurisdiction and that there is no appeal nor any plain, speedy and adequate remedy in the ordinary course of law for the purpose of amending or nullifying the proceeding.6 [Suntay v. Cojunagco-Suntay, 300 SCRA 760, 766 (1998)]

The records of the present case clearly reveal that the motion for reconsideration filed by the private respondents lacks the requisite notice of hearing.7 [Supra Note 5, at 45.]

The law on the matter is clear. The rules on procedure explicitly require that notice of a motion shall be served by the applicant to all parties concerned at least three days before the hearing thereof together with a copy of the motion, and of any affidavits and other papers accompanying it,8 [RULES OF COURT, Rule 15, Sec. 4.] and that the notice shall be directed to the parties concerned, stating the time and place for hearing the motion.9 [RULES OF COURT, Rule 15, Sec. 5.] This requirement of notice of hearing equally applies to a motion for reconsideration.10 [Sembrano v. Ramirez, 166 SCRA 30, 36 (1988) citing Firme v, Reyes, 92 SCRA 713, 716 (1979), Republic Planters Bank v. Intermediate Appellate Court, 131 SCRA 631, 637 (1984)] We have invariably held that a motion without notice of hearing is a mere scrap of paper.11 [De la Peña, 258 SCRA 298, 302 (1996), Manila Electric Company v. La Campana Food Products, Inc., 247 SCRA 77, 82 (1995)] In other words, a pro forma motion for reconsideration does not suspend the running of the period to appeal. In the instant case, the failure of private respondents to comply with the procedural requirements was fatal to their right to appeal.12 [Pojas v. Gozo-Dalole, 192 SCRA 575, 578 (1990) citing New Japan Motors, Inc. v. Perucho, 74 SCRA 14, 19 (1976), Filipinas Fabricators & Sales, Inc. v. Magsino, 157 SCRA 469, 474(1988)]

But, having lost their right to appeal due to their own procedural lapse, were private respondents likewise deprived of any other plain, speedy, and adequate remedy in the ordinary course of law?

Under the Rules of Court,13 [Rule 38, Sec. 2.] private respondents still had recourse to a petition for relief from the trial court's order within sixty days from notice or receipt of the questioned order.14 [Rule 38, Sec. 3.]A petition for relief from judgment, orders, or other proceedings is a plain, speedy, and adequate remedy in the ordinary course of law.

In our view, the trial court committed no error nor grave abuse of discretion amounting to lack of excess of jurisdiction when: (a) it denied private respondents' pro forma motion for reconsideration; (b) ruled that private respondents' period to appeal had already lapsed, as the defective motion for reconsideration did not toll the period to appeal; and (c) held that its order of June 2, 1993 had already become final and executory. In so doing, the trial court correctly applied the law and jurisprudence on the matter. And since private respondents had recourse to a petition for relief from the trial court's order, their remedies in the ordinary course of law had not yet been exhausted so as to justify resort to certiorari under Rule 65. Certiorari did not lie as far as private respondents were concerned. Plainly it was error for the appellate court to have issued the extraordinary writ of certiorari in CA-G.R. SP No. 31816.

On the issue of whether the appellate court was correct in modifying its earlier judgment in CA-G.R. CV No. 32893, we note that in CA-G.R. SP No. 31816, the Court of Appeals substantially amended the fallo of CA-G.R. CV No. 32983 by ordering that the interest due private respondents be compounded and capitalized periodically. Resolving whether this amendment is proper entails a prior determination as to whether the decision in CA-G.R. CV No. 32983 had already become final and executory.

The records show that the decision of the appellate court in CA-G.R. CV No. 32983 dated May 29, 1992 was not appealed by either party. Failure of a party to perfect his appeal in the manner and within the period prescribed by law renders the decision final, with the result that no court can exercise jurisdiction to review said final decision.15 [Uy v. Court of Appeals, 286 SCRA 343, 351 (1998)] Once a decision is final and executory, it can no longer be attacked by any party or be modified directly or indirectly, even by the Court.16 [Panado v. Court of Appeals, 298 SCRA 110, 121 (1998)] The exceptions are the correction of clerical errors or the making of nunc pro tunc entries which cause no prejudice to either party, or where the judgment is void.17 [Industrial and Transport Equipment, Inc. v. NLRC, 284 SCRA 144, 149 (1998)] Since, a decision or judgment which has become final and executory can neither be amended nor altered even if the purpose is to correct a perceived flaw in the conclusion of fact or law, the appellate court committed a reversible error of law when it amended its disposition in CA-G.R. CV No. 32983 through its ruling in CA-G.R. SP No. 31816. Even at the risk of an error or two, a judgment must at some time attain finality. Once final, that judgment should be deemed as the law of the case.

WHEREFORE, the petition is GRANTED. The assailed Decision of the respondent appellate court dated October 28, 1994, and its Resolution dated May 18, 1995, in CA-G.R. SP No. 31816, are SET ASIDE. Let the parties be guided by the Decision of the Court of Appeals dated May 29, 1992 in CA-G.R. CV No. 32983, which is hereby REINSTATED in full.

No pronouncement as to costs.
