MANILA (UPDATED) — Sen. Robinhood Padilla on Monday confirmed he has filed separate resolution seeking to dismiss the impeachment case of Vice President Sara Duterte.

In Senate Resolution 1371, Padilla noted that “all pending matters and proceedings will terminate upon the expiration of one Congress” once the 19th Congress adjourns sine die on Friday, June 13.

"The Articles of Impeachment against Vice-President Sara Zimmerman Duterte is one such pending matter, and the consideration thereof  is one such pending proceeding," he said.

Padilla earlier said his resolution is his own and has nothing to do with other similar resolutions. He also said he did not consult the vice president about it.

"May kaniya-kaniya kaming isip, may kaniya-kaniya kaming gawa, may kaniya-kaniya kaming staff," he said.

Sen. Ronald "Bato" dela Rosa earlier admitted to initiating a similar resolution.

Critics and lawyers had pointed out that dismissing the impeachment case of Duterte was not part of the process, and the Senate should hold the trial immediately, as mandated by the 1987 Constitution.

A member of the House prosecution panel had even called a possible Senate dismissal of the impeachment case "unconstitutional."

Padilla and Dela Rosa are drafting resolutions seeking to dismiss the impeachment case even after several senators, members of the academe, and political analysts called on the Senate to "forthwith proceed" with the trial.

The House of Representatives impeached Duterte on February 5 for "high crimes" including corruption and an alleged assassination plot against former ally and running mate President Ferdinand Marcos Jr.

Senate President Francis "Chiz" Escudero had announced that the prosecution panel's scheduled presentation at the Senate would be moved to June 11 instead of June 2, citing the tackling of "priority legislative measures before the 19th Congress adjourns" as the reason for the postponement.

Individual members of the University of the Philippines College of Law Faculty said Tuesday in an open letter that the Senate's possible dismissal of the impeachment case "without hearing even a single witness will mean its abandonment of its proud tradition as an august chamber and permanently alter our system of checks and balances."

"Respectfully, a dismissal at this point would be deemed by the Filipino people as effectively engineered by the Senate's own delay and an abdication of its constitutional role in impeachment," they said.
