G.R. No. 170928 ; September 11, 2007
VICENTE S. ALMARIO, Petitioner, vs. PHILIPPINE AIRLINES, INC., Respondent.

FACTS

Petitioner Vicente S. Almario was hired by respondent Philippine Airlines, Inc. (PAL) in 1988. In 1995, he successfully bid for the higher position of Airbus 300 First Officer, which required extensive training funded by PAL. After completing the training and serving for eight months, Almario tendered his resignation in September 1996. PAL demanded reimbursement for the training costs, amounting to PHP 786,713.00, claiming an implied agreement that Almario would serve for three years to allow PAL to recover its investment. Almario refused, asserting no such written agreement existed in their Collective Bargaining Agreement (CBA).
PAL filed a complaint for reimbursement before the Makati Regional Trial Court (RTC). The RTC dismissed PAL’s complaint and awarded damages to Almario, finding no contractual stipulation for reimbursement. The Court of Appeals reversed the RTC, holding Almario liable under the CBA and the principle of unjust enrichment. Almario elevated the case to the Supreme Court via petition for review.

ISSUE

Whether Vicente S. Almario is obligated to reimburse Philippine Airlines, Inc. for the training costs incurred for his Airbus 300 First Officer training after resigning before a claimed three-year service period.

RULING

The Supreme Court denied the petition and affirmed the Court of Appeals’ decision. The Court held that while no express written contract stipulated reimbursement, the obligation arose from the principle of unjust enrichment under Article 22 of the Civil Code. The legal logic is rooted in equity: one shall not be unjustly enriched at the expense of another. PAL invested substantial funds in Almario’s specialized training with the clear expectation of derived benefit from his service. By resigning shortly after completing the training, Almario deprived PAL of the chance to recoup its investment, thereby obtaining a benefit (costly training enhancing his skills and marketability) without rendering the commensurate service, to PAL’s detriment.
The Court found the CBA provision, which “froze” pilots aged 57 from bidding for higher positions due to the prohibitive cost of training relative to the three years left before mandatory retirement, indicative of the mutual understanding of a three-year cost recovery period. This context, coupled with the absence of any showing that Almario paid for his training, established that his resignation after only eight months of service constituted unjust enrichment. Consequently, he was ordered to reimburse PAL the net training cost, offset by his accrued benefits, amounting to PHP 559,739.90.
