Any rule change, including a creation, amendment, or repeal, made to implement a statutory change must be adopted and filed with the legislative council within nine months of the effective date of the statutory change. If an agency or the commission needs additional time for the rule change, a request for additional time must be made to the legislative council. The legislative council may extend the time within which the agency or commission must adopt the rule change if the request by the agency or commission is supported by evidence that the agency or commission needs more time through no deliberate fault of its own.
