X 10 yr. ---------------------23,589.80
"Multiplied by no. of complainants x 21
"TOTAL LIABILITY OF
and (3) the resolution that denied petitioner's motion for reconsideration.
The facts are as follows:
In August 1979, petitioner Tag Fibers, Inc. absorbed respondents from its predecessors, Smith Bell and Company, Conrad and Company and Columbian Rope and company as regular and permanent employees until the second week of February 1983, when they were all terminated because of company losses. On February 11, 1983, petitioner Tag Fibers, Inc. re-hired respondents Ricardo Abanes and twenty (20) others effective on the day after the termination of their employment as piece-rate workers.
On July 25, 1983, when petitioners learned that respondents filed a complaint with the Regional Director, Region VII, Ministry of Labor & Employment for violation of the Minimum Wage Law and the granting of cost of living allowances, petitioners prohibited them from working.
On August 22, 1983, respondents filed with the Labor Arbiter a complaint for illegal dismissal with reinstatement and payment of backwages, cost of living allowances and other benefits.
On January 11, 1985, Labor Arbiter Felipe T. Garduque III rendered a decision disposing as follows:
"WHEREFORE, responsive to all the foregoing, respondent TAG FIBER INC., and/or RAFAEL ZULUAGA, Jr., is hereby ordered to reinstate complainants to their respective former positions without loss of seniority rights and privileges and to pay jointly an severally the total sum of TEN THOUSAND EIGHT HUNDRED FIFTY EIGHT PESOS AND 68/100 (P10,858.68) to be deposited with this office within ten (10) days from receipt of this Decision for appropriate disposition.
"Cebu City, Philippines, 11 January 1985.
"FELIPE T. GARDUQUE II
On February 1, 1985, petitioners appealed to the National Labor Relations Commission (NLRC).
On February 17, 1986, the NLRC dismissed the appeal for lack of merit and affirmed the decision of the Labor Arbiter.
On September 5, 1986, respondents filed with the Labor Arbiter a motion for the issuance of a writ of execution.
On October 15, 1986, petitioners filed with the Supreme Court a petition for certiorari for the nullification of the NLRC decision.
On October 5, 1987, the Court dismissed the petition for failure to sufficiently show that the respondent Commission had committed a grave abuse of discretion in rendering the questioned judgment.
Meantime, on January 22, 1987, Labor arbiter Alhambra Llenos Alfafara issued the corresponding writ of execution.
On February 15, 1993, Labor Arbiter Reynoso A. Belarmino issued another writ of execution of the January 15, 1985 decision of Labor Arbiter Felipe T. Garduque, in execution of which petitioners paid respondents the full amount of the monetary award of P10,858.68, but refused to reinstate the respondents. During the execution proceedings, respondents pressed for more backwages that was not provided in the Garduque decision. Consequently, the issue of reinstatement was set for a conference between the parties.
On March 23, 1993, the Labor Arbiter set the conference between the parties. However, on May 3, 1993, respondents filed a motion to direct petitioners to pay them backwages in view of petitioners' refusal to reinstate them.
On July 12, 1993, Labor Arbiter Reynoso a. Belarmino issued a resolution finding that strained relationship existed between the employer and employees and resolved to grant respondents the sum of P27,300.00 each or a total of P573,300, in the concept of separation pay of P2,730.00 each per year of service from February 1983 to June 1993.
On April 19, 1995, the NLRC modified the above-mentioned resolution of the Labor Arbiter. On May 11, 1995, petitioners filed with the NLRC a motion for reconsideration of the April 19, 1995 resolution assailing the grant of separation pay in lieu of reinstatement. On May 26, 1995, the NLRC denied petitioner's motion for reconsideration.
Hence, this petition.
Petitioners contend that the monetary aspect of the judgment dated January 11, 1985 has been satisfied an the Labor Arbiter's authority to enforce judgment is merely ministerial; hence, the Labor Arbiter cannot modify or vary the final and executory decision of the NLRC.
We find the petition is meritorious.
Under Rule 39, Section 6, 1964 Revised Rules of Court, a judgment may be executed on motion within five (5) years from the date of its entry or from the date it becomes final and executory.
After the lapse of such time, and before it is barred by the statute of limitations, a judgment may be enforced by action. This rule applies to the case as the Rules of Court are applicable to labor cases in a suppletory capacity.
In this particular case, the January 11, 1985 decision of Labor Arbiter Felipe T. Garduque II became final after the NLRC denied petitioner's motion for reconsideration on July 30, 1986. Hence, the Labor Arbiter had no jurisdiction when he set a conference on March 23, 1993. The conference could no longer be lawfully convoked.
When the NLRC issued the resolution ordering the petitioner to pay separation pay from February 1983 to June 1993, it modified its own final judgment, and worse, acted without jurisdiction. The finality of a decision is a jurisdictional event that cannot be made to depend on the convenience of a party.
WHEREFORE, the Court GRANTS the petition and SETS ASIDE the NLRC resolution in NLRC Case No. 701-82 dated July 12, 1993, the resolution in NLRC Case NO. V-0392-93, promulgated on April 19, 1995, and the resolution in the same case promulgated on May 26, 1995, which are hereby declared VOID.
