Lopez vs. Roxas

The Court held that Republic Act No. 1793 is constitutional because it merely vests additional original jurisdiction in the Supreme Court rather than creating a new or inferior court. The power to judge election contests is inherently judicial, and the Constitution’s silence regarding presidential and vice-presidential contests leaves Congress with the discretion to authorize such proceedings and designate the competent judicial body. Accordingly, the Supreme Court, when functioning as the PET, exercises valid jurisdiction over the protest without contravening the separation of powers or the constitutional tenure of the proclaimed officers.

The 1965 general elections placed petitioner Fernando Lopez and respondent Gerardo Roxas as the principal candidates for Vice-President. Congress, convening as the national board of canvassers, issued Resolution No. 2 on December 17, 1965, proclaiming Lopez the winner with a plurality of 26,724 votes over Roxas. Roxas subsequently filed Election Protest No. 2 before the Presidential Electoral Tribunal, alleging that he actually secured the highest number of votes. Lopez sought to enjoin the Tribunal from proceeding, asserting that the enabling statute was unconstitutional and that all its proceedings were void.

• Following the November 9, 1965 elections, Congress convened as the national board of canvassers and issued Resolution No. 2 on December 17, 1965, proclaiming Fernando Lopez as the elected Vice-President based on a certified tally of 3,531,550 votes against Gerardo Roxas’s 3,504,826 votes.
• On January 5, 1966, Roxas filed Election Protest No. 2 before the Presidential Electoral Tribunal, contesting Lopez’s proclamation and asserting that he had actually obtained the largest number of votes for the office.
• On February 22, 1966, Lopez instituted an original action for prohibition with preliminary injunction before the Supreme Court to restrain the Tribunal from hearing or deciding the protest.
• Lopez grounded his petition on the alleged unconstitutionality of Republic Act No. 1793, which established the Presidential Electoral Tribunal, and contended that the statute effectively nullified Congress’s canvassing authority, violated the separation of powers, and improperly imposed judicial duties on Supreme Court Justices without executive appointment.

• Petitioner maintained that Congress lacked constitutional authority to authorize election contests for the President and Vice-President, as the fundamental law remained silent on the matter and the Constitutional Convention had deliberately rejected a provision for an electoral commission.
• Petitioner argued that permitting judicial contests nullified Congress’s exclusive constitutional power to canvass votes and proclaim the winners, and that a judicial recount would improperly override ministerial executive-legislative functions.
• Petitioner contended that Republic Act No. 1793 effectively amended the Constitution by creating an electoral body that the people understood to be limited to congressional contests only.
• Petitioner asserted that the tenure of the President and Vice-President is fixed by the Constitution and cannot be curtailed or invalidated by an ordinary statute authorizing post-proclamation challenges.
• Petitioner claimed that requiring Supreme Court Justices to sit on the Tribunal rendered it an inferior court whose decisions could theoretically be appealed to the Supreme Court, thereby violating the constitutional vesting of judicial power and constituting an unlawful congressional appointment.

• Respondent defended the constitutionality of Republic Act No. 1793, maintaining that Congress possesses the legislative discretion to render presidential and vice-presidential election contests justiciable and to designate the Supreme Court as the competent tribunal.
• Respondent argued that the statute did not create a separate or inferior court, but merely imposed additional judicial functions upon the existing constitutional court, thereby preserving the unitary character of the Supreme Court.
• Respondent countered that the Tribunal’s jurisdiction to verify election returns and conduct recounts operates independently of and does not conflict with Congress’s ministerial duty to canvass and proclaim results.

• Procedural Issues: Whether the Supreme Court has jurisdiction to entertain an original action for prohibition against a tribunal composed of its own members, and whether the election protest should be docketed separately from the Supreme Court’s main records.
• Substantive Issues: Whether Republic Act No. 1793, which created the Presidential Electoral Tribunal and vested it with exclusive jurisdiction over election contests involving the President and Vice-President, is constitutional; and whether the statute violates the separation of powers, infringes upon Congress’s canvassing authority, unlawfully abridges the constitutional tenure of elected officials, or constitutes an unconstitutional appointment by Congress.

• Procedural: The Court held that the Presidential Electoral Tribunal is not a distinct or inferior court but is identical to the Supreme Court exercising additional functions. Consequently, the petition for prohibition was dismissed, and the motion to transfer the protest records to the Supreme Court as a separate entity was denied.
• Substantive: The Court ruled that Republic Act No. 1793 is constitutional. The power to adjudicate election contests is inherently judicial. Because the Constitution expressly vested this power in the Senate and House Electoral Tribunals for congressional members, it implicitly left Congress with the discretion to determine whether contests for the President and Vice-President are justiciable and to designate the competent court. The statute did not create a new tribunal but merely conferred additional original jurisdiction upon the Supreme Court. The legislative grant did not violate the separation of powers, encroach upon the Executive’s appointing power, or abridge constitutional tenure, as a successful protest merely establishes that the proclaimed candidate never legally acquired the office.

• Nature of Judicial Power and Legislative Jurisdiction-Conferment — Judicial power encompasses the authority to settle justiciable controversies involving enforceable rights, and Congress holds the constitutional prerogative to define, prescribe, and apportion judicial jurisdiction. The Court applied this doctrine to validate Republic Act No. 1793 as a permissible legislative expansion of the Court’s judicial functions, ruling that Congress may render previously non-justiciable political contests cognizable by the courts and designate the adjudicating body.
• Unity of the Court and Multiplicity of Functions — A single judicial tribunal may exercise distinct and separate functions without losing its unitary character or becoming inferior to itself. The Court applied this principle to rule that the Supreme Court, when sitting as the Presidential Electoral Tribunal, remains the same constitutional body exercising a specialized jurisdictional mandate, thereby negating claims that the Tribunal constitutes an inferior court or that its members were improperly appointed by Congress.

• "The proper exercise of said authority requires legislative action: (1) defining such enforceable and demandable rights and/or prescribing remedies for violations thereof; and (2) determining the court with jurisdiction to hear and decide said controversies or disputes, in the first instance and/or on appeal." — The Court used this formulation to establish that Congress holds the constitutional prerogative to render election contests for the President and Vice-President justiciable and to designate the adjudicating body, thereby justifying the passage of Republic Act No. 1793.
• "In other words, there is only one court, although it may perform the functions pertaining to several types of courts, each having some characteristics different from those of the others." — This passage articulates the principle that vesting the Supreme Court with the functions of the Presidential Electoral Tribunal does not create a new or inferior entity, but merely expands the functional scope of the existing constitutional court.

• Channie Tan v. Republic — Cited to illustrate that controversies remain non-justiciable absent legislative authorization, thereby supporting the premise that Congress must first enact a statute like Republic Act No. 1793 before election contests for the presidency or vice-presidency become cognizable by the courts.
• Mabanag v. Vito — Referenced to affirm that political questions fall outside judicial review unless the Constitution or statute expressly confers jurisdiction upon the courts to resolve them, reinforcing the Court’s analysis of justiciability.
• In re Guariña and United States v. Limsiongco — Invoked as precedent establishing that the legislature may validly add to, but not diminish, the jurisdiction of the Supreme Court without violating constitutional constraints, directly supporting the validity of the additional jurisdiction conferred by Republic Act No. 1793.

• Article VIII, Sections 1 and 2 of the 1935 Constitution — Cited as the constitutional basis for the vesting of judicial power in the Supreme Court and inferior courts, and for Congress’s authority to define, prescribe, and apportion judicial jurisdiction.
• Article VI, Section 11 of the 1935 Constitution — Referenced to demonstrate that the Constitution expressly vested the power to judge election contests for congressional members in the respective Electoral Tribunals, thereby excluding such contests from the general grant of judicial power and implying congressional discretion over contests for other executive officers.
• Article VII, Section 2 of the 1935 Constitution — Cited to characterize Congress’s canvassing function as a ministerial and executive duty, which remains distinct from and consistent with the judicial power of the Presidential Electoral Tribunal to verify the authenticity of election returns and conduct recounts.
• Republic Act No. 1793 — The enabling statute under review, which established the Presidential Electoral Tribunal and vested it with exclusive original jurisdiction over election contests involving the President and Vice-President.

• Justices Reyes, Barrera, Dizon, Regala, Makalintal, J.P. Bengzon, Zaldivar, Sanchez, and Castro — Concurred fully with the ponencia without issuing separate opinions, thereby endorsing the Court’s en banc ruling on the constitutionality of Republic Act No. 1793 and the denial of the petition for prohibition.
