Data notes

The final version of the law, as each chamber passed it. A chamber that passed it by voice vote or unanimous consent has no count. “Method not stated” means the record does not say how the chamber voted. Where the record has a member-by-member vote, the “Who voted for it” section shows who voted yea.
