G.R. No. L-9769; August 30, 1957.
Ramon J. Guico, petitioner, vs. Estate of Florencio P. Buan, oppositor-respondent.

FACTS

On December 6, 1954, petitioner Ramon J. Guico applied for a certificate of public convenience to operate a bus service on the lines Bangued-Manila, Laoag-Manila, Vigan-Manila, and Aparri-Manila (the last line was later dropped from the application). On December 17, 1954, the Estate of Florencio P. Buan, an existing operator on the lines applied for, filed an application for authority to run additional trips on those same lines and opposed Guico’s application. Other transportation companies also opposed. The two applications were heard jointly by the Public Service Commission. The Commission found a need for more trips on the lines, but not to the extent proposed by both applicants. It authorized an additional 11 round trips daily (4 on Laoag-Manila, 5 on Vigan-Manila, and 2 on Bangued-Manila). The Commission awarded all these additional trips to the Estate of Buan, preferring it as the established operator with the means, capacity, and experience to maintain the service, and applying the doctrine of protection to an existing operator. Guico appealed the decision.

ISSUE

1. Whether the Public Service Commission correctly determined that only 11 additional round trips were needed.
2. Whether the Commission erred in awarding all the authorized additional trips to the Estate of Buan instead of to Guico.

RULING

1. The Supreme Court affirmed the Commission’s factual determination that 11 additional round trips were sufficient to meet the public need. The Court held that the number of trips required is a factual matter subject to many variables, and the Commission, with its supervisory role and access to its own records, is in the best position to appraise such needs. The Court found no grave abuse of discretion warranting interference with the Commission’s estimate, as it was supported by evidence.
2. The Supreme Court upheld the Commission’s award of all additional trips to the Estate of Buan. The Court ruled that:
a. The Estate of Buan was an established operator entitled to protection. It held a certificate for the line Aparri-Manila via Claveria and Vigan, which included the Vigan-Manila segment as an intermediate portion.
b. Priority in filing the application (Guico filed first) does not defeat the right to protection of an established operator on long-distance lines requiring substantial capital and reliable service.
c. The Commission correctly found that the Estate of Buan had the experience, trained personnel, capital, and a record of regular and continuous service since 1952, making it better suited to serve the public interest.
d. Whose evidence proved the need for additional service is not decisive; the paramount consideration is which operator can best subserve the public interest.
The decision of the Public Service Commission was affirmed, with costs against petitioner Guico.
