Adjournment sine die
Adjournment sine die is the conclusion of a meeting by a deliberative assembly, such as a legislature or organizational board, without setting a date to reconvene. The assembly can reconvene, either in its present form or a reconstituted form, if preexisting laws and rules provide for this. Otherwise the adjournment effectively dissolves the assembly.
A court may also adjourn a matter sine die, which means that the matter is stayed until further notice. In a sine die adjournment of this type, the hearing stands open indefinitely, and could theoretically be resumed if the situation changed.
United States usage
The Congress of the [United States] customarily adjourns a session sine die on the morning of January 3, immediately before the next session holds its constitutionally mandated first meeting. 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.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.
In the Florida Legislature, the sergeants-at-arms of the Florida Senate and the Florida House of Representatives step outside their chambers each holding a handkerchief. When they meet in between the chambers, they both drop the handkerchiefs, signifying the end of the legislative session.
