Here are selected August 2009 Philippine Supreme Court decisions on political law:
Congress; legislative immunity. The immunity Senator Santiago claims is rooted primarily on the provision of Article VI, Section 11 of the Constitution.
As American jurisprudence puts it, this legislative privilege is founded upon long experience and arises as a means of perpetuating inviolate the functioning process of the legislative department. Without parliamentary immunity, parliament, or its equivalent, would degenerate into a polite and ineffective debating forum. Legislators are immune from deterrents to the uninhibited discharge of their legislative duties, not for their private indulgence, but for the public good. The privilege would be of little value if they could be subjected to the cost and inconvenience and distractions of a trial upon a conclusion of the pleader, or to the hazard of a judgment against them based upon a judge’s speculation as to the motives.
This Court is aware of the need and has in fact been in the forefront in upholding the institution of parliamentary immunity and promotion of free speech. Neither has the Court lost sight of the importance of the legislative and oversight functions of the Congress that enable this representative body to look diligently into every affair of government, investigate and denounce anomalies, and talk about how the country and its citizens are being served. Courts do not interfere with the legislature or its members in the manner they perform their functions in the legislative floor or in committee rooms. Any claim of an unworthy purpose or of the falsity and mala fides of the statement uttered by the member of the Congress does not destroy the privilege. The disciplinary authority of the assembly and the voters, not the courts, can properly discourage or correct such abuses committed in the name of parliamentary immunity.
For the above reasons, the plea of Senator Santiago for the dismissal of the complaint for disbarment or disciplinary action is well taken. Indeed, her privilege speech is not actionable criminally or in a disciplinary proceeding under the Rules of Court. It is felt, however, that this could not be the last word on the matter. Antero J. Pobre vs. Sen. Miriam Defensor-Santiago, A.C. No. 7399. August 25, 2009.
