Wyoming Constitution Art. 4, § 8. Approval or veto of legislation by governor; passage over veto

Every bill which has passed the legislature shall, before it becomes a law, be presented to the governor. If he approve, he shall sign it; but if not, he shall return it with his objections to the house in which it originated, which shall enter the objections at large upon the journal and proceed to reconsider it. If, after such reconsideration, two-thirds of the members elected agree to pass the bill, it shall be sent, together with the objections, to the other house, by which it shall likewise be reconsidered, and if it be approved by two-thirds of the members elected, it shall become a law; but in all such cases the vote of both houses shall be determined by the yeas and nays, and the names of the members voting for and against the bill shall be entered upon the journal of each house respectively. If any bill is not returned by the governor within three days (Sundays excepted) after its presentation to him, the same shall be a law, unless the legislature by its adjournment, prevent its return, in which case it shall be a law, unless he shall file the same with his objections in the office of the secretary of state within fifteen days after such adjournment.
