Explanation:

Adjournment sine die (from the Latin "without day") means "without assigning a day for a further meeting or hearing". To adjourn an assembly sine die is to adjourn it for an indefinite period. A legislative body adjourns sine die when it adjourns without appointing a day on which to appear or assemble again. It can be used in reference to United States legislatures whose ter ms or mandates are coming to an end, and it is anticipated that this particular body will not meet again in its present session, form, or membership.A legislative body adjourned in this way may be called back into special session, a reason why sine die adjournment rather than dissolution may be preferred in some cases.
