Miss. Const. art. 4, § 72
Every Bill which shall pass both Houses shall be presented to the Governor of the state. If he approve, he shall sign it; but if he does not approve, he shall return it, with his objections, to the House in which it originated, which shall enter the objections at large upon its Journal, and proceed to reconsider it. If after such reconsideration two-thirds (2/3) of that House shall agree to pass the Bill, it shall be sent, with the objections, to the other House, by which, likewise, it shall be reconsidered; and if approved by two-thirds (2/3) of that House, it shall become a law; but in all such cases the votes of both Houses shall be determined by yeas and nays, and the names of the persons voting for and against the Bill shall be entered on the Journal of each House respectively. If any Bill shall not be returned by the Governor within five (5) days (Sundays excepted) after it has been presented to him, it shall become a law in like manner as if he had signed it, unless the Legislature, by adjournment, prevented its return, in which case such Bill shall be a law unless the Governor shall veto it within fifteen (15) days (Sundays excepted) after it is presented to him, and such Bill shall be returned to the Legislature, with his objections, within three (3) days after the beginning of the next session of the Legislature.
