G.R. No. L-23453 May 31, 1974
MARTINIANO P. VIVO, petitioner, vs. HON. RODOLFO T. GANZON, et al., respondents.

FACTS

Petitioner Martiniano P. Vivo, the then Acting Commissioner of Immigration, filed this application for habeas corpus seeking release from detention ordered by respondent Senator Rodolfo T. Ganzon as Chairman of the Senate Committee on Labor and Immigration. Vivo had appeared before the committee, but upon noticing that only Chairman Ganzon was present, with the six other members absent, he sought to be excused from testifying on the ground that there was no quorum for a valid committee meeting. Respondent Ganzon brushed aside the request, declared a recess, and upon resuming, asked preliminary questions. When Vivo declined to answer, pleading that the committee as a whole should rule on his objection, Ganzon declared him in contempt and ordered the Senate Sergeant-at-Arms and other respondents to place him under arrest and detention.
Vivo alleged his detention was without due process and not by virtue of any valid warrant, arguing that Ganzon lacked authority to order arrest for contempt as the committee was not lawfully convened. This Court initially granted the writ, ordered a hearing, and released Vivo upon posting a bond. Respondents, in their answer, maintained the action was lawful, citing a Senate resolution authorizing committees to function during recess and a certification from the six absent members stating they had given implied consent to the Chairman to conduct hearings and exercise all prerogatives, including contempt powers.

ISSUE

Whether the order of detention issued by respondent Senator Ganzon against petitioner Vivo for alleged contempt of the Senate Committee remains valid and enforceable.

RULING

The Court declared the provisional release of petitioner Vivo permanent and the order of detention issued by respondent Ganzon to be without any force or effect. The legal logic is grounded on a supervening event: the abolition of the Senate under the 1973 Constitution. The Court noted that with the Senate abolished and replaced by a unicameral National Assembly, the order of confinement had lost any juridical basis, even assuming it had validity when issued. The constitutional framework governing legislative inquiries had changed; the new Constitution vested legislative power in a National Assembly, with provisions for inquiries in aid of legislation under duly published rules.
Thus, instead of resolving the significant legal issues argued by the parties and amici curiae—such as the validity of a one-member committee meeting, the existence of a quorum, and the delegation of contempt powers by absent members—the Court found it unnecessary to pass on them. The more appropriate course was to await a case arising under the new constitutional provision if it should arise. Consequently, with the Senate abolished, the basis for the detention order ceased to exist, rendering the habeas corpus petition moot and entitling Vivo to permanent liberty. No costs were awarded.
