G.R. No. 31629 - Manila Electric Co. vs. Pasay Trans. Co., Inc.

On July 16, 1928, the Manila Electric Company applied for a certificate of public convenience to operate an auto-bus line along Taft Avenue Extension.
The proposed route began at the corner of F. B. Harrison and S. Vitan Streets and proceeded along Taft Avenue, Padre Burgos Street, Plaza Lawton, and Santa Cruz Bridge, then extended to Plaza Goiti or Jones Bridge to Plaza Moraga, returning via the same route.

On July 17, 1928, the Pasay Transportation Co., Inc. filed its own application for a certificate of public convenience for operating auto-bus services along the Taft Avenue Extension.
The appellant asserted that it had long maintained an auto-bus service from F. B. Harrison Street to the Divisoria Market via Libertad, Dominga, and Vito Cruz Streets, contending that its established operation should entitle it to preference over a new entrant on a similar route.

The Public Service Commission granted the certificate of public convenience to the Manila Electric Company.
Conversely, the application of the Pasay Transportation Co., Inc. was denied.
Following the denial, the Pasay Transportation Co., Inc. filed a petition for review, challenging the decision on the grounds of unfair competition and preferential rights derived from its long-standing service.

Whether the Public Service Commission erred in granting the certificate of public convenience to the Manila Electric Company despite the objections raised by the Pasay Transportation Co., Inc.

The appellant argued that its established auto-bus service in the municipality of Pasay merited preferential treatment.
The argument underscored the potential for unfair competition should the approved route overlap substantially with the appellant's existing service areas.

Whether the evidence in the record sufficiently supported the Commission’s decision to deny the Pasay Transportation Co., Inc. a certificate when both companies sought to operate on the Taft Avenue Extension.

Consideration was given to the actual routes of both companies and the nature of the passenger traffic in the district.
The issue extended to whether the heavy passenger traffic warranted multiple operators even if overlapping exists in part of their routes.
