G.R. No. 121084 February 19, 1997
Toyota Motor Philippines Corporation, petitioner, vs. Toyota Motor Philippines Corporation Labor Union and the Secretary of Labor and Employment, respondents.

FACTS

Toyota Motor Philippines Corporation Labor Union (TMPCLU) filed a petition for certification election for rank-and-file employees. Toyota opposed the petition on two grounds: first, that TMPCLU lacked legal personality as it was merely “in the process of registration” at the time of filing; and second, that the union’s membership improperly included both rank-and-file and supervisory employees, violating Article 245 of the Labor Code. The Med-Arbiter dismissed the petition, upholding both grounds.
On appeal, the Secretary of Labor initially reversed the Med-Arbiter, finding that TMPCLU had been issued a certificate of registration two days before filing the petition and that the alleged mixture of employees was a matter for inclusion/exclusion proceedings during the pre-election conference. However, upon Toyota’s motion for reconsideration, the Secretary remanded the case for a factual hearing on the exact date of TMPCLU’s registration. The Med-Arbiter, after hearing, found it was “unlikely” the certificate was issued on the claimed date, suggesting the union was not yet legitimate when it filed its petition.

ISSUE

Whether the respondent union possessed the legal personality to file a petition for certification election.

RULING

The Supreme Court granted Toyota’s petition and reinstated the Med-Arbiter’s order dismissing the certification election petition. The legal logic centered on the union’s composition, which rendered the technical issue of registration timing irrelevant. The Court found that TMPCLU’s membership list included at least twenty-seven supervisory employees. Article 245 of the Labor Code explicitly prohibits supervisory employees from joining a union of rank-and-file employees. Consequently, a labor organization with such a mixed membership cannot attain the status of a legitimate labor organization. Without being a legitimate labor organization, TMPCLU lacked the requisite legal personality to file a petition for certification election. The Court emphasized that this prohibition is fundamental to ensuring the integrity of bargaining units and preventing conflicts of interest, as supervisory employees act in the interest of the employer in relation to rank-and-file workers. Therefore, regardless of the procedural findings on the certificate of registration date, the union’s inherently flawed composition was a fatal defect that barred its petition.
