A bill or resolution passed by the senate and the house of representatives of the legislative assembly as evidenced by the journals of the senate and house is presumed to be the bill or resolution that is signed by the presiding officers of the senate and house, presented to the governor, and filed with the secretary of state. If there is a difference between versions of a bill, the legislative council shall direct the publisher of the code to publish the law according to this section. The law as published must be presumed valid until determined otherwise by an appropriate court.
