Sine Die

Sine die is a term for the adjournment of an assembly for an indefinite period, from the Latin “without day”. In March 1989, Oklahoma voters approved State Question 620,  which provided that regular legislative sessions begin on the first Monday in February and adjourn sine die not later than 5:00 pm on the last Friday in May. Special sessions are also adjourned sine die but there is no set date for their adjournment.
