If the Governor receives the bill while the legislature is in session, he has five calendar days, exclusive of Sundays and holidays, in which to sign or veto the bill. If the bill is vetoed it is returned to the chamber in which it originated with a statement of his objections. The bill may be reconsidered and, if passed by at least two-thirds of the members of each chamber of the General Assembly, it becomes law. If the Governor does not sign or veto the bill within five calendar days, it automatically becomes law, unless the General Assembly has adjourned the regular or special session. If the regular or special session has adjourned, the bill becomes law unless the Governor, within fifteen calendar days after it has been presented to him, transmits it to the Secretary of the State with his objections. In such case, the bill does not become law unless it is reconsidered and re-passed by the General Assembly by at least two-thirds of the members of each chamber of the General Assembly for its constitutionally mandated Veto Session.
