Sine die is a Latin term meaning 'without a day,' and it is used in legislative contexts to indicate that a meeting or session has been adjourned indefinitely, without scheduling a specific date for resumption. This can occur at the end of a legislative session or when a committee decides not to take further action on a bill. The use of sine die often signifies the conclusion of discussions or proceedings on particular matters, reflecting both the urgency and finality of legislative actions.
