G.R. No. L-53492, L-54265, L-54394, L-54565 December 29, 1986
Pernito Arrastre Services, Inc., et al. vs. Hon. Rafael T. Mendoza, et al. (Consolidated Cases)

FACTS

These consolidated petitions sought to permanently restrain the Philippine Ports Authority (PPA) from taking over arrastre and stevedoring operations at the Port of Tacloban. The petitioners, various arrastre service operators and laborers, invoked constitutional rights to due process and non-impairment of contracts. The controversy stemmed from a government policy to integrate port services. Initially, an Ad Hoc Committee recommended integrating arrastre and stevedoring operations per port to address problems like the oppressive “cabo system,” theft, and violence. Following this, the Bureau of Customs issued Memorandum Order No. 28-75 in 1975, mandating the merger of cargo-handling contractors.
Upon the effectivity of Presidential Decree No. 857 in 1975, regulatory powers over port operations were transferred to the PPA. The PPA adopted the integration policy via its own Memorandum Order No. 21-77. In Tacloban, numerous contractors were gradually merged, culminating in the formation of petitioner Leyte Integrated Port Services, Inc. (LIPSI), which received a temporary permit from PPA in 1978. However, PPA later cancelled LIPSI’s permit and assumed direct control of Tacloban arrastre operations through its entity, PPA-TAPS, prompting the legal challenges.

ISSUE

Whether the PPA’s policy of compulsory integration of arrastre services and its subsequent takeover of operations constitute a valid exercise of police power, notwithstanding claims of violation of due process and impairment of contractual obligations.

RULING

The Supreme Court dismissed the petitions, upholding the PPA’s actions as a legitimate exercise of the state’s police power. The Court clarified that the constitutional guarantees of due process and non-impairment of contracts are not absolute and must yield to the superior demand of public interest and general welfare. Port operations, including arrastre and stevedoring, are imbued with public interest as they directly affect national and international trade, commerce, and the economy. As such, they are subject to reasonable regulation by the state.
The legal logic is grounded in the state’s inherent authority to regulate businesses affected with public interest. Presidential Decree No. 857 expressly vested the PPA with broad powers to regulate and oversee port services to ensure efficiency, security, and regional development. The integration policy, designed to streamline operations, eliminate systemic abuses, and improve service, is a reasonable regulatory measure. The Court found that the takeover did not create an unlawful monopoly, as PPA-TAPS absorbed the existing labor force, effectively maintaining the integrated structure. The temporary permit granted to LIPSI was revocable at the PPA’s discretion, and its cancellation following the policy shift was justified. The state’s police power, exercised here through the PPA to promote public welfare, prevails over private contractual rights or claims of exclusive operation.
