Manila Prince Hotel v GSIS G.R. No. 122156, February 3, 1997 Facts: System (GSIS) planned to sell 30% to 51% of the outstanding shares of Manila Hotel Corporation via public bidding as part of the Philippine government's privatization program. On September 18, 1995, there were only two (2) bidders: Manila Prince Hotel Business, a Filipino corporation, and Renong Berhad, a Malaysian firm, which offered Php 2.42 more than the Manila Prince Hotel Corporation bid. As the losing bidder, MPH matched the bid price of Php 44.00 per share which the GSIS refused to accept. On October 17, 1995, MPH came to the Court on prohibition and mandamus, invoking Section 10, par. 2, Art. XII of the 1987 Constitution and contends that the Manila Hotel has practically become a historical monument which reflects the vibrancy of Philippine heritage and culture. As a result, it has become part of the national patrimony. Corollary, as a Filipino corporation, it should be chosen after matching the Malaysian firm's bid offer. Issue: Whether or not the provisions of the Constitution, particularly Article XII Section 10, are selfexecuting. Held: The Supreme Court ruled that Section 10, par. 2, Art. XII of the 1987 Constitution is a mandatory, positive command which is complete in itself and which needs no further guidelines or implementing laws or rules for its enforcement. The 1987 Constitution mandated that [i]n the grant of rights, privileges, and concessions covering national economy and patrimony, the State shall give preference to qualified Filipinos, it means just that --- qualified Filipinos shall be preferred. The Supreme Court also argued that those found in Art. II of the 1987 Constitution, which lays down a general principle, are usually not self-executing. But a provision which is complete in itself and becomes operative without the aid of supplementary or enabling legislation, or that which supplies sufficient rule by means of which the right it grants may be enjoyed or protected, is self-executing. If the constitutional provisions are treated as requiring legislation instead of self-executing, the legislature would have the power to ignore and practically nullify the mandate of the fundamental law. That is why the prevailing law is that “in case of doubt, the Constitution should be considered self-executing rather than non-self-executing x x x Unless the contrary is clearly intended, the provisions of the Constitution should be considered self-executing, as a contrary rule would give the legislature discretion to determine when, or whether, they shall be effective. These provisions would be subordinated to the will of the lawmaking body, which could make them entirely meaningless by simply refusing to pass the needed implementing statute.
