Historic Oversight in the Philippines Senate: Escudero May Preside Over Sara Duterte's Impeachment Case

The impeachment case against Philippine Vice President Sara Duterte continues to be one of the most significant political crises on the country's agenda. The appointment of Senator Chiz Escudero to preside over this historic trial process has sparked widespread debate in political circles. Escudero was officially selected for the presiding role in the hearing held on Monday, July 6. However, senators led by the Cayetano siblings from the minority bloc did everything in their power to block this appointment. Senator Alan Peter Cayetano objected to the process, claiming that current Senate President Sherwin Gatchalian should preside over the case as required by the Constitution.

Cayetano attempted to defend his argument by referencing the provisions of the 1987 Constitution and the records of the constitutional commission. However, legal experts and constitutional scholars point out that the Senate President is only replaced by the Chief Justice of the Supreme Court when the President of the Philippines is tried, leaving the process to the Senate for all other cases. University of the Philippines College of Law Associate Dean Paolo Tamase explicitly stated that the Constitution appoints a special presiding officer only for the trial of the president. Law Professor John Malo also emphasizes that the constitutional text is extremely clear and that the Senate has the authority to set its own rules for impeachment cases other than that of the president.

The revised rules of the Philippines Senate regarding impeachment cases also clearly support this situation. Senate President Sherwin Gatchalian announced that the Senate Resolution No. 48 was adopted and went into effect on June 3. With this new regulation, a senator other than the Senate President legally gained the ability to preside over the trial by a majority vote. This rule change is of vital importance for understanding the power dynamics within the Senate and following the operation of the case. Gatchalian's stance invalidated the objections of the minority bloc and removed the legal obstacles in front of Escudero presiding over the trial.

The identity of the person who will preside over the impeachment cases is of great importance, as it will directly determine the course and pace of the process. The presiding officer will have broad authorities, such as issuing court orders, publishing writings, and implementing all regulations authorized by the Senate. The impeachment process is a constitutional mechanism with profound political consequences rather than an ordinary trial. In this process, which will determine Sara Duterte's fate, the minority bloc sought a presiding structure that could influence the process in their favor by considering the Vice President's inclinations. However, with Escudero's appointment to this role, these tactical calculations have proven ineffective.

Looking at the political history of the Philippines, it is seen that impeachment cases are mostly presided over by the Chief Justice or the Senate President. Former Chief Justice Hilario Davide Jr. presided over the impeachment case of former President Joseph Estrada between December 2000 and January 2001. Former Senate President Juan Ponce Enrile presided over the trial of former Chief Justice Renato Corona. Experts taking this historical context into account state that Senate President Escudero assuming this role in Duterte's case is neither a constitutional violation nor an unprecedented situation. The developments have once again proven how independent the Philippines Senate is in shaping political trials according to its own internal rules by using its legal authorities.
