• Article III, Sections 4 and 7 (freedom of speech and right against self-incrimination)
• Article IV, Section 1 (separation of powers)

Background and Nature of Executive Order No. 464
E.O. 464, titled “Ensuring Observance of the Principle of Separation of Powers, Adherence to the Rule on Executive Privilege and Respect for the Rights of Public Officials Appearing in Legislative Inquiries,” provided:
- Department heads require presidential consent before any appearance before either House (Section 1).
- Definition and scope of “executive privilege” over confidential presidential communications, national security matters, pre-treaty negotiations, and Cabinet deliberations (Section 2(a)); designation of covered public‐sector officials (Section 2(b)).
- Requirement that designated senior executive, military and police officers secure presidential consent before appearing in inquiries in aid of legislation (Section 3).
Issues Presented
- Does E.O. 464 infringe Congress’s constitutional power of inquiry in aid of legislation?
- Does it violate the people’s right to information on matters of public concern?
- Was the Order validly implemented prior to publication?
- Do the Order’s provisions constitute an unconstitutional delegation of executive privilege?
Power of Inquiry Under Article VI, Section 21
- The Constitution expressly empowers either House or its committees to “conduct inquiries in aid of legislation,” enforceable by compulsory process and respecting the rights of witnesses.
- Historical jurisprudence (Arnault v. Nazareno) confirms that the power of inquiry is incidental to effective lawmaking and extends to executive‐branch officials possessing necessary information.
Distinction Between Inquiry and Question Hour
- Article VI, Section 22 (question hour) allows—but does not compel—department heads to appear before Congress, requiring presidential consent or voluntary initiative.
- Article VI, Section 21 (inquiry in aid of legislation) compels appearance, subject only to valid claims of privilege.
Executive Privilege: Nature and Limits
- Executive privilege is rooted in separation of powers and shields narrow categories of sensitive information (e.g., presidential communications, military/diplomatic secrets, Cabinet deliberations).
- Jurisprudence (U.S. v. Nixon; Almonte v. Vasquez; Chavez v. PCGG; Chavez v. PEA) recognizes the privilege but mandates a case-by-case, fact-specific assertion, supported by a clear formal claim and balancing of interests.
Validity of Section 1 (Question Hour)
- Section 1, governing discretionary “question hour” appearances under Article VI, Section 22, is consistent with the Constitution and valid on its face.
- It does not apply to mandatory inquiries in aid of legislation.
Invalidity of Sections 2(b) and 3 (Compulsory Consent and Delegation)
- Sections 2(b) and 3 authorize “implied” presidential‐privilege determinations by department heads, AFP/PNP commanders or National Security Adviser, without requiring a precise, formal claim.
- Such indirect, prophylactic withholding frustrates Congress’s investigatory power and lacks the particularized showing needed to invoke executive privilege.
- The President alone may assert executive privilege or specifically delegate that authority; subdelegation by silence or broad discretion is impermissible.
Section 2(a) (Privilege Definition)
- Section 2(a) merely art
Case Syllabus (G.R. No. L-48437)
Facts
- The Senate, various lawmakers, party-list groups, NGOs, legal practitioners and the Integrated Bar of the Philippines filed consolidated petitions (G.R. Nos. 169659, 169660, 169667, 169777, 169834, 171246) challenging Executive Order No. 464 (E.O. 464) of September 28, 2005.
- E.O. 464 requires heads of executive departments and certain senior officials to secure the President’s consent before appearing before either House of Congress.
- Senate hearings on (a) the North Luzon Railways (“NorthRail”) project and (b) alleged wiretapping by the ISAFP were scheduled for September 28–29, 2005. Invited officials of the Executive Department declined or sought postponements, citing E.O. 464.
- Some AFP officers who appeared nonetheless were relieved of duty and faced court-martial; other executive officials sent regrets under E.O. 464.
- Petitioners asserted that E.O. 464 unconstitutionally frustrated Congress’s power of inquiry and deprived the public of its right to information.
Procedural History
- October 3–14, 2005: Petitions for certiorari and prohibition filed before the Supreme Court seeking nullification of E.O. 464 and a restraining order against its enforcement.
- February 21, 2006: Oral arguments conducted; parties instructed to submit memoranda addressing (1) facial unconstitutionality and (2) as-applied challenges in four instances (Fertilizer Fund, NorthRail, wiretapping, Venable contract).
- March 7–8, 2006: Petitioners filed memoranda; respondent submitted consolidated memorandum March 13, 2006.
- April 20, 2006: En Banc decision rendered.
Issues
- Does E.O. 464 impair Congress’s power to conduct inquiries in aid of legislation (Art. VI, Sec. 21)?
- Does E.O. 464 violate the people’s right to information on matters of public concern (Art. III, Sec. 7; Art. II, Sec. 28)?
- Does E.O. 464 unlawfully delegate executive privilege determinations to department heads (Secs. 2(b) & 3)?
- Was E.O. 464 implemented without the required publication, amounting to grave abuse of discretion?
