G.R. No. 174340 , 174318, 174177; October 17, 2006
Camilo L. Sabio, et al. vs. Hon. Senator Richard Gordon, et al.

FACTS

The Senate Committee on Government Corporations and Public Enterprises, pursuant to Senate Resolution No. 455, initiated an inquiry into alleged anomalous losses and improprieties in the operations of the Philippine Communications Satellite Corporation (PHILCOMSAT) and its related entities. The Senate issued subpoenae ad testificandum to Camilo L. Sabio, Chairman of the Presidential Commission on Good Government (PCGG), other PCGG Commissioners, and several corporate officers of PHILCOMSAT Holdings Corporation, requiring them to appear and testify. The PCGG, which holds sequestered shares in these corporations, invoked Section 4(b) of Executive Order No. 1, which provides that “No member or staff of the Commission shall be required to testify or produce evidence in any judicial, legislative or administrative proceeding concerning matters within its official cognizance.” The petitioners refused to comply with the subpoenae, leading to the filing of consolidated petitions challenging the Senate’s power to compel their attendance.

ISSUE

The core issue is whether Section 4(b) of Executive Order No. 1, which grants PCGG members immunity from testifying in legislative inquiries, is constitutional in light of the Senate’s power of inquiry in aid of legislation under Article VI, Section 21 of the 1987 Constitution .

RULING

The Supreme Court declared Section 4(b) of E.O. No. 1 unconstitutional. The Court held that the Senate’s power of inquiry, while not explicitly mentioned in the Constitution, is inherent in and essential to its legislative function. This power is broad, encompassing all matters within the scope of legitimate legislative interest, and includes the compulsory process to secure testimony and documents. The immunity provision in E.O. No. 1 constitutes an impermissible legislative encroachment, as it prescribes a blanket prohibition that effectively negates a co-equal branch’s constitutional power without any limiting principle. The Court emphasized that while the power of inquiry is not absolute and must be exercised in accordance with the Senate’s duly published rules and with respect for individual rights, a mere executive issuance cannot nullify a core legislative power derived from the Constitution. The legitimate need for the PCGG to perform its functions confidentially does not justify a categorical exemption from a legislative inquiry conducted in accordance with constitutional parameters. The proper balance is achieved by the Senate respecting valid claims of privilege, such as executive privilege, on a case-by-case basis, not by a prior statutory grant of absolute immunity.
