Legal scholars and former magistrates convened at the Malcolm Theatre in UP Diliman on 19 February 2026 to examine the Supreme Court’s ruling in Duterte v. House of Representatives and its long-term implications for impeachment in the Philippines.
The academic forum focused on how the Court’s decision may reshape impeachment as a constitutional accountability mechanism and redefine the balance among the branches of government.
Retired Supreme Court Senior Associate Justice Antonio T. Carpio opened the discussion by highlighting what he described as the critical importance of the concept of “session days.”
Session Days at the Center
Retired Senior Associate Justice Carpio explained that the term “session day” has a technical parliamentary meaning rooted in long-standing legislative practice.
According to him, a session day traditionally functions to stop the legislative clock, allowing deliberations to continue without consuming additional legislative days.
He warned that redefining session days could significantly affect constitutional timelines governing impeachment proceedings.
The forum emphasized that the issue goes beyond personalities and instead raises structural constitutional questions with lasting institutional consequences.
Focus on Institutional Impact
Organizers clarified that the event was not intended to relitigate specific impeachment complaints but to examine broader constitutional effects, including:
- Whether impeachment doctrine has materially changed
- Whether judicial review has expanded into congressional procedure
- What the long-term consequences may be for accountability mechanisms
Speakers repeatedly underscored that impeachment remains a core democratic safeguard whose procedural integrity must be preserved.
