THE AI-ASSISTED CRITIQUE
The Court’s reliance on Cabanero vs. Torres and the principle that prohibition is a preventive remedy is technically sound, as the writ cannot undo a completed act. However, the decision’s formalistic application of this procedural bar sidesteps a substantive examination of the mayor’s alleged usurpation of legislative power under section 2444, paragraph (z) of the Revised Administrative Code, which vested the municipal board with the authority to establish public markets. By treating the market’s establishment as a fait accompli based on the city engineer’s certification of completion, the Court implicitly condoned an executive act that may have circumvented the legislative process, setting a concerning precedent where expediency could undermine statutory divisions of authority.

The characterization of unfinished toilet facilities and booth construction as “mere details” is a legally vulnerable point. This reasoning minimizes the functional definition of a “public market” as an operational public utility, which arguably was not fully realized until essential services were complete and vendors were formally settled. A stricter interpretation might have found the act not yet “consummated” for the purposes of prohibition, allowing the Court to reach the core jurisdictional issue. The decision thus prioritizes administrative finality over a potential ultra vires analysis, leaving unresolved whether the mayor’s expenditure of funds and initiation of construction, based merely on a board “approval in principle,” constituted a valid administrative implementation or an unlawful preemption of the ordinance-making process.

Ultimately, the ruling creates a pragmatic but legally precarious incentive: an executive branch could theoretically accelerate physical completion of a contested project to invoke the fait accompli doctrine and immunize its actions from judicial review via prohibition. While the outcome achieved a practical result—clearing public nuisances from streets—it did so at the cost of a muted check on executive overreach. The Court missed an opportunity to clarify the limits of executive authority in relation to pending legislative appropriations, leaving the boundaries between administrative initiative and legislative encroachment dangerously blurred for future local governance disputes.
