§18. Gubernatorial Action on Bills; Sign, Failure to Sign, Veto; Veto Session
Section 18.(A) Gubernatorial Action. If the governor does not approve a bill, he may
veto it. A bill, except a joint resolution, shall become law if the governor signs it or if he
fails to sign or veto it within ten days after delivery to him if the legislature is in the session
in which the bill passed on the tenth day after such delivery, or within twenty days after
delivery if the tenth day after delivery occurs after the legislative session in which the bill
passed is adjourned.
(B) Veto Message. If the governor vetoes a bill, he shall return it to the legislature,
with his veto message, within twelve days after delivery to him if the legislature is in the
session in which the bill passed. If the governor returns a vetoed bill after the legislative
session in which the bill passed is adjourned, he shall return it, with his veto message, as
provided by law.
(C) Veto Session. (1) A bill vetoed and returned and subsequently approved by
two-thirds of the elected members of each house shall become law. The legislature shall
meet in veto session in the state capital at noon on the fortieth day following final
adjournment of each session in which a bill that finally passed was vetoed, to consider all
bills passed during that session that were vetoed by the governor and that were not
reconsidered by the house of origin during the session in which the bill passed. If the fortieth
day falls on Sunday, the session shall convene at noon on the succeeding Monday. No veto
session shall exceed five calendar days, and any veto session may be finally adjourned prior
to the end of the fifth day upon a vote of two-thirds of the elected members of each house.
(2) No veto session shall be held if a majority of the elected members of either house
declare in writing that a veto session is unnecessary. The declaration must be received by
the presiding officer of the respective houses at least five days prior to the day on which the
veto session is to convene.
(3) If a veto session is to be held and the time period for the conduct of the veto
session occurs during a regular or extraordinary session of the legislature, the legislature may
reconsider all bills vetoed by the governor and not previously reconsidered by the legislature
as part of the business of the regular or extraordinary session during the time period set forth
in Subparagraph (1) of this Paragraph without the necessity of convening or adjourning a
separate veto session.
