For purposes of issuing a resolution for the Articles of Impeachment, the House of Representatives of the Philippines Committee on Justice, issued several subpoenas for the compulsory production of evidence against the Vice President Inday Sara Duterte
During this time, the question that must be answered is: is the House Committee on Justice empowered to issue a subpoena in aid of impeachment?
As established by jurisprudence, the House, pursuant to Article VI, Section 21 of the 1987 Constitution, and incidental to its power to legislate, is traditionally recognized to have power of issuing a subpoena “in aid of legislation.” This power allows them to have the right information that can provide the much-needed guidance on finalizing a bill. This power, without a doubt, is innate with the House.
Is the impeachment process in the house “in aid of legislation”? Does the terminal end of impeachment produce a law? By impeachment, is any law amended or modified? The answer is no. No production, amendment, or modification of the law is effected by the conclusion of the impeachment. Hence, impeachment proceedings are not “in aid of legislation.”
So does the House Committee on Justice empowered to issue a subpoena in aid of impeachment?
Not yet. It is my view that at this stage of the proceedings, the house in not yet empowered to issue subpoenas. However, when the impeachment court convenes, and the house elects it panel of prosecutors, and the senate sits as an impeachment court judges, then, through a motion, can the prosecutor, move for subpoena for the production of evidence.
Before this, any new matter to be fished through subpoenas, with the purpose of adding to the previously filed verified complaint is an exercise of power that is not found in the constitution. Further, this new fished information is NOT PART of the original verified complaint, hence, the same is a "new" allegation, that, under the Constitution, must be filed through another verified impeachment complaint.
Under Article XI of the Constitution, an impeachment proceeding is initiated through the "Filing of a Verified Complaint" and it is doubtful that an article of impeachment can pass constitutionality if the allegations therein is not one of those substantially and completely described in the original verified complaint.
