A putting off or postponing of proceedings; an ending or dismissal of further business by a court, legislature, or public official—either temporarily or permanently.
If an adjournment is final, it is said to be sine die, "without day" or without a time fixed to resume the work. An adjournment is different from a recess, which is only a short break in proceedings.
In legislatures, adjournment officially marks the end of a regular session. Both state and federal lawmakers vote to determine when to adjourn. The exact timing depends upon multiple factors such as work load, election schedules, and the level of comity among lawmakers. Because a session can end with unfinished legislative business, adjournment is commonly used as a means of political leverage in securing or delaying action on important matters. In the U.S. Congress, where the single annual legislative session usually ends in the fall, the president may call an adjournment if the House and Senate cannot agree upon a date.
