THE AI-ASSISTED CRITIQUE
The commission’s exclusion of evidence regarding abandonment was procedurally flawed, as the evidence was directly relevant to the petitioner’s counter-petition for cancellation in the consolidated case. By hearing the application for sale and the opposition jointly, the commission created a single proceeding where all material issues, including the alleged abandonment justifying forfeiture under Public Service Act principles, should have been fully ventilated. The court correctly identifies this as error but deems it non-reversible, relying on the commission’s judicial notice of its own records—a principle supported by precedents like Manila Yellow Taxicab Co. vs. Araullo. This approach, however, risks insulating administrative determinations from adversarial testing, as it allows the commission to rely on internal knowledge rather than evidence formally presented and subject to cross-examination by the opposing party.

The court’s deference to the commission’s factual finding—that Damortis was within the certificate’s territory and that no abandonment occurred—exemplifies the limited scope of judicial review over administrative agencies at the time. Citing Calabia vs. Orlanes & Banaag Transportation Co., the standard required a showing of “no evidence” to reasonably support the decision, a high bar that effectively presumes regularity. This deference is consistent with the era’s administrative law but raises concerns about substantive due process when the commission itself curtails evidence on a central issue. The ruling underscores that challenges must demonstrate not merely erroneous weighing of evidence, but a complete absence of rational basis, a doctrine that can shield arbitrary outcomes if applied too rigidly.

Ultimately, the decision hinges on the commission’s authority under section 33 of Commonwealth Act No. 146 to order immediate effect of its rulings, a discretionary power upheld here. The court’s affirmation reinforces the commission’s broad managerial control over public utilities, including approving transfers and denying expansions based on existing service obligations. While the outcome may be justified, the procedural shortcut—sustaining an objection to relevant evidence while taking official notice—creates a problematic precedent. It allows an agency to both limit the record and then fill gaps with its own unexamined assertions, potentially undermining the adversarial process in quasi-judicial proceedings.
