Withdrawal from the Compact is permitted pursuant to Article XII, section A of the agreement. A state may withdraw by enacting a statute specifically repealing the agreement. The effective date of withdrawal is the effective date of the repeal, provided that repealing the agreement does not relieve a state of any pending financial obligations it may have to the Commission. Therefore, a state cannot avoid paying assessments, obligations or other liabilities, including any financial penalties imposed by the Commission or a court simply by repealing the agreement. Such obligations extend beyond the date of any repeal and are subject to judicial enforcement even after a state has withdrawn from the ICAOS.
