We start with the concept of “sine die.” Derived from Latin, it means “without a day.” When a legislative body adjourns sine die, it ends a session without setting a date for reconvening. Traditionally, this marks the conclusion of legislative business.
But was the Senate business effectively halted before a valid and functioning chamber could complete its work?
The Constitution vests legislative authority in the Senate as an institution, not in any single officer. A Senate President presides over the chamber, but does not own it. If the presiding officer’s absence or refusal to convene prevents the Senate from performing its constitutional duties, the question becomes whether the remaining members are powerless to act.
History suggests “no.”
On 5 May 2015, the Senate conducted sessions with only 12 senators present. Then Senate President Franklin Drilon ruled that a quorum existed after determining that the senators who were either detained or abroad on official business should not be counted in computing the number necessary to transact business. The ruling was accepted as a valid exercise of the chamber’s authority to interpret its own rules, and the Senate proceeded with its work.
The precedent is significant because legislative bodies have long been accorded substantial discretion in determining whether or not they have a quorum.
