Title
Pimentel, Jr. vs. Office of the Executive Secretary
Case
G.R. No. 158088
Decision Date
Jul 6, 2005
Petitioners sought mandamus to compel executive transmission of the Rome Statute to the Senate for ratification; SC ruled no ministerial duty exists without presidential ratification, dismissing the petition.

Case Summary (G.R. No. 158088)

Petition Background

Petitioners allege that under Section 21, Article VII of the 1987 Constitution and customary international law (Vienna Convention on the Law of Treaties), the executive must submit the Rome Statute for Senate ratification. They contend that the Senate holds exclusive power to ratify treaties and that non‐transmittal thwarts both domestic and international obligations.

Treaty Details and Signature

The Rome Statute, establishing the International Criminal Court with jurisdiction over genocide, crimes against humanity, war crimes, and aggression, opened for signature in Rome on July 17, 1998, and closed December 31, 2000, in New York. The Philippines, through Charge d’Affaires Enrique A. Manalo, signed the Statute on December 28, 2000. Signature alone does not bind a state; ratification, acceptance, or approval remains necessary.

Procedural Posture and Respondents’ Arguments

Petition for mandamus filed under Rule 65, Section 3, 1997 Rules of Civil Procedure. The Solicitor General challenges standing and asserts that neither the Office of the Executive Secretary nor the Department of Foreign Affairs has a ministerial duty to forward a treaty they have not ratified. Respondents further maintain that mandamus cannot override executive discretion in foreign affairs.

Jurisdiction and Standing

Mandamus requires a petitioner to demonstrate a clear legal right and direct interest. The Court found only Senator Pimentel to be “aggrieved” because the power of the Senate to concur in treaties directly affects each member’s prerogatives. Other petitioners lacked proof of direct injury from non‐transmittal and thus lacked standing.

Constitutional Framework of Treaty-Making

The President, as sole organ in foreign relations, possesses exclusive authority to negotiate and enter into treaties. The 1987 Constitution curtails this power by mandating concurrence of two‐thirds of all Senate members for treaty validity (Section 21, Article VII). Historical constitutions similarly framed legislative participation as a check on executive treaty‐making.

Executive Order No. 459 Guidelines

Under EO 459 (November 25, 1997), after signature the Department of Foreign Affairs prepares ratification papers for the President. Only upon Presidential ratification does DFA submit the treaty, with ratification instrument, to the Senate for concurrence. Concurrence then triggers entry into force in the Philippines.

Distinction Between Signature and Ratification

Signature authenticates a treaty text and evidences good faith negotiations but does not reflect the state’s final consent. Ratification is the formal executive act by which a state confirms treaty o
