ISSUE: Whether or not Resolutions 67 & 68 was validly approved.
FACTS: The petitioners, Senator Jose Avelino, in a quo warranto proceeding, asked the court to declare him the rightful Senate President and oust the respondent, Mariano Cuenco. In a session of the Senate, Tanada’s request to deliver a speech in order to formulate charges against then Senate President Avelino was approved. With the leadership of the Senate President followed by his supporters, they deliberately tried to delay and prevent Tanada from delivering his speech. The SP with his supporters employed delaying tactics, the tried to adjourn the session then walked out. Only 12 Senators were left in the hall. The members of the senate left continued the session and Senator Cuenco was appointed as the Acting President of the Senate and was recognized the next day by the President of the Philippines.
RATIO DECIDENDI: It was held that there is a quorum that 12 being the majority of 23. In fine, all the four justice agree that the Court being confronted with the practical situation that of the twenty three senators who may participate in the Senate deliberations in the days immediately after this decision, twelve senators will support Senator Cuenco and, at most, eleven will side with Senator Avelino, it would be most injudicious to declare the latter as the rightful President of the Senate, that office being essentially one that depends exclusively upon the will of the majority of the senators, the rule of the Senate about tenure of the President of that body being amenable at any time by that majority. And at any session hereafter held with thirteen or more senators, in order to avoid all controversy arising from the divergence of opinion here about quorum and for the benefit of all concerned,the said twelve senators who approved the resolutions herein involved could ratify all their acts and thereby place them beyond the shadow of a doubt.
