In a sine die adjournment of this type, the hearing stands open indefinitely, and could theoretically be resumed if the situation changed.
It can also adjourn sine die at other times through a concurrent resolution that allows the Speaker of the House and Senate Majority Leader to resume the session.
[4] State legislatures follow suit and mark adjournment sine die with a ceremony, such as the Connecticut General Assembly wherein, on the final day of the legislative session, the House and Senate meet in a joint convention, and the Secretary of the State recites "Oyez, Oyez, Oyez", pounds the gavel, and declares the legislature adjourned sine die.
When they meet in between the chambers, they both drop the handkerchiefs, signifying the end of the legislative session.
Under both House and Senate rules, the only substantive matters which can be heard are resolutions making technical corrections to legislation already passed; otherwise, the only other matters which can be heard are congratulatory and memorial resolutions, and other honorary items (such as a caucus deciding on informal awards).
