Cunanan vs. Tan, Jr.

The Court held that the Commission on Appointments is an independent constitutional body whose members are entitled to a measure of stability in tenure, and that a House of Congress cannot declare vacant its representatives in the Commission solely on the basis of a temporary shifting of legislative alliances. Because the constitutional requirement of proportional representation refers to permanent party affiliation rather than transient voting coalitions, the reorganization of the Commission by the House of Representatives was invalid, rendering the subsequent rejection of the petitioner’s ad interim appointment void ab initio.

In early 1962, the Fifth Congress opened with the Senate evenly divided between the Liberal and Nacionalista Parties, resulting in Senator Eulogio Rodriguez, Sr. serving as Acting Senate President. The House of Representatives, though numerically controlled by the Nacionalista Party, saw the formation of an "Allied Majority" comprising all 29 Liberal members and 25 Nacionalista members. This coalition moved to reorganize the Commission on Appointments by declaring the existing House representatives' seats vacant and electing new members aligned with the coalition. Shortly thereafter, this reconstituted group purportedly convened as the Commission and rejected the ad interim appointment of petitioner Carlos Cunanan to the position of Deputy Administrator of the Reforestation Administration. The President then designated respondent Jorge Tan, Jr. to the same office, prompting petitioner to file a quo warranto proceeding to assert his right to the position.

• Petitioner Carlos Cunanan, a career government employee, was appointed Acting Deputy Administrator of the Reforestation Administration on June 6 or 8, 1961, and subsequently received an ad interim appointment to the same position on November 6, 1961. He qualified and assumed office.
• On March 21, 1962, an "Allied Majority" in the House of Representatives, composed of 29 Liberal congressmen and 25 Nacionalista congressmen, passed a resolution declaring the seats of the twelve House members in the Commission on Appointments vacant. The House subsequently elected new representatives to the Commission, replacing three Nacionalista members with three others who aligned with the coalition.
• On April 3, 1962, thirteen legislators—six Liberal Senators, four Liberal Congressmen, and three Nacionalista Congressmen aligned with the Allied Majority—purported to convene as the Commission on Appointments and rejected petitioner’s ad interim appointment.
• On April 11, 1962, the President designated respondent Jorge Tan, Jr. as Acting Deputy Administrator. Respondent assumed office without petitioner’s consent.
• Petitioner filed a quo warranto proceeding, contending that the April 3 rejection was invalid because the reconstituted Commission lacked legal authority, and therefore the office was never vacant when respondent was designated.

• Petitioner maintained that the Commission on Appointments that rejected his ad interim appointment was illegally constituted because the House of Representatives lacked constitutional authority to declare its members' seats vacant based on a temporary voting coalition.
• Petitioner argued that the March 21, 1962 resolution of the House and the subsequent April 3 rejection were null and void, leaving his ad interim appointment valid and his right to the office intact.
• Petitioner further alleged that a subsequent meeting of the legitimate Commission on Appointments on April 27, 1962, confirmed his ad interim appointment, reinforcing his entitlement to the position.

• Respondent contended that the House of Representatives acted within its constitutional prerogative in declaring the Commission seats vacant and electing new members based on proportional representation.
• Respondent defended the validity of the April 3 rejection, asserting that the reconstituted Commission legally exercised its power to reject the petitioner’s ad interim appointment, thereby creating a vacancy that justified the President’s designation of respondent.
• Respondent denied the petitioner’s allegation of subsequent confirmation by the original Commission members, challenging the factual basis of petitioner’s claim to the office.

• Procedural Issues: Whether the Supreme Court possesses jurisdiction to review the internal resolution of the House of Representatives declaring Commission on Appointments seats vacant and re-electing its members.
• Substantive Issues: Whether the House of Representatives validly exercised its constitutional authority to reorganize the Commission on Appointments based on a temporary legislative coalition, and whether the subsequent rejection of the petitioner’s ad interim appointment was legally valid.

• Procedural: The Court exercised jurisdiction to determine the constitutionality of the House resolution, holding that while Congress organizes the Commission, the Commission itself is an independent constitutional body whose composition cannot be arbitrarily altered by a House acting on temporary political realignments. The Court refused to treat the House’s internal election of Commission members as a non-justiciable political question when constitutional mandates on proportional representation and tenure stability are directly implicated.
• Substantive: The Court ruled that the House of Representatives’ March 21, 1962 resolution and the April 3 rejection of petitioner’s appointment are null and void. Because the Commission on Appointments derives its authority directly from the Constitution and functions independently of Congress, its members must enjoy stability of tenure to ensure freedom of action. The constitutional mandate for proportional representation refers to permanent party affiliation, not transient voting alliances like the "Allied Majority." Consequently, the petitioner’s ad interim appointment remained valid, the office was never vacant, and respondent’s designation was invalid. Petitioner was ordered to assume office, and respondent was directed to vacate it.

• Constitutional Independence and Stability of Tenure of the Commission on Appointments — The Court established that the Commission on Appointments is a constitutional body independent of Congress, and its members are entitled to a measure of stability in tenure to insulate their functions from partisan political shifts. Temporary changes in legislative voting coalitions do not justify the reorganization of the Commission, as the constitutional requirement of proportional representation is anchored in the enduring party composition of each House, not in transient political alliances.

• "One thing, however, is to take these measures owing to changes of permanent character in the representation of the political parties in the House, and another thing for some members thereof affiliated with a political party to make common cause in certain matters with members of the House belonging to another political party." — The Court used this distinction to clarify that the constitutional authority to reorganize the Commission on Appointments applies only to permanent shifts in party affiliation, not to temporary legislative coalitions.
• "The Commission on Appointments is it creature of the Constitution. Although its membership is confined to members of Congress, said Commission is independent of Congress. The powers of the Commission do not come from Congress, but emanate directly from the Constitution." — This passage anchors the Court’s reasoning that the Commission’s independence and constitutional mandate shield it from arbitrary reorganization by either House of Congress.

• Cabili v. Francisco — Cited by Justice Bautista Angelo in his concurring opinion to support the doctrine that Commission members enjoy stability of tenure and cannot be removed or substituted merely due to subsequent political realignments within the Senate or House until new elections occur.
• Aytona v. Castillo — Cited by Justice Padilla in his dissenting opinion to argue that the petitioner’s ad interim appointment lapsed upon the adjournment of Congress, thereby extinguishing his right to the office.
• Vera v. Avelino, Avelino v. Cuenco — Referenced in the dissent to support the principle that courts generally cannot interfere with the internal organization and functions of a House of Congress, though the majority distinguished this principle in the context of a constitutional body’s composition.

• Section 12, Article VI, 1935 Constitution — The governing constitutional provision establishing the Commission on Appointments, mandating its composition of twelve Senators and twelve Representatives elected on the basis of proportional representation of political parties. The Court interpreted this provision to require stability and permanent party alignment rather than temporary coalition-based reallocation.
• Section 11, Article VI, 1935 Constitution — Cited by Justice Padilla to contrast the election process for Electoral Tribunal members (nominated by parties) with that of Commission on Appointments members (elected by the House), emphasizing that the latter’s proportional representation requirement was satisfied regardless of internal House voting dynamics.

• Justice Bautista Angelo — Concurred with the majority, emphasizing that party affiliation is a requisite qualification for Commission membership, but the Constitution contemplates stability of tenure to ensure liberty of action free from party squabbles. He argued that the original selection reflects the electorate’s will and cannot be altered by subsequent legislative realignments until a new national election confirms a new party alignment.

• Justice Padilla — Dissented on two grounds. First, he maintained that the petitioner’s ad interim appointment expired on December 30, 1961, pursuant to the doctrine in Aytona v. Castillo, leaving petitioner with no remaining right to the office. Second, he argued that the Court cannot review the House’s internal action declaring Commission seats vacant and electing new members, as such organizational acts are beyond judicial interference and do not transgress constitutional provisions on proportional representation.
