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 overwhelmingly approved State Question 620, a voter-initiated constitutional amendment providing 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.
