Case Summary (G.R. No. L-61461)

Factual and Procedural Background

PANTRANCO held CPCs for passenger and freight bus operations from Metro Manila to Eastern Visayas. In March 1980 it sought MARINA approval to operate M/V Black Double between Matnog and Allen as an incident to its highway franchise. MARINA declined, citing adequate service by petitioners and market constraints. PANTRANCO acquired the vessel in May 1981 and commenced operations without further authority. BOT enjoined its operation pending formal application.

Position of Petitioners and BOT’s Rationale

Epitacio San Pablo’s heirs and Cardinal Shipping contended that the Matnog–Allen route was already adequately served and that PANTRANCO could not lawfully intrude without its own CPC. BOT solicited the Justice Minister’s opinion, which—relying on public utility efficiency principles—concluded that incidental ferry service would be superfluous to require separate certification. BOT then motu proprio amended PANTRANCO’s CPC to authorize a “private ferryboat service” exclusively for its buses, passengers, and trucks, subject to separate CPC if opened to the public.

Legal Issue and Statutory Framework

The core question was whether the Matnog–Allen sea passage qualified as a mere ferry (continuation of highway) or as a coastwise/interisland shipping service requiring independent certification. The Public Service Act mandates formal application, publication, hearing, and compliance with MARINA and BOT regulations for coastwise carriers. Prior decisions (e.g., Javellana) distinguish short water crossings by barges or small vessels from longer open-sea voyages, the latter properly classified as coastwise trade.

Analysis of Matnog–Allen Service

Judicial notice of geography and navigational conditions shows that San Bernardino Strait is an open-sea channel subject to tides, rough waters, and a 23-kilometer span requiring about 1½–2 hours of navigation by motor vessel. These characteristics exceed the limited, short-distance river or lake crossings traditionally deemed ferries. Safety and vessel requirements align instead with interis
