Two thirds of each House has to vote to override the Governor's veto, the Bill becomes a law.
The legislature can pass a bill over his veto by a two-thirds vote in some states, a three-fifths vote in others, or in a few states by a bare majority.
2/3 majority vote
Yes! A governor may veto the bill, but then it would take a 3/5 vote from both houses (Senate and House of Representatives) to override the governor's veto. If the governor does nothing with the bill for 60 days it automatically becomes a law.
reopen the bill
That is an example of separation of powers. Only the general assembly can make laws, but governor can veto them if he chooses.
60 days
reopen the bill.
A bill that the governor (for a state bill) or president (for a US Congressional bill) refuses to sign is said to be VETOED.
Any bill not returned by the Governor within 60 calendar days after it is presented to him shall become law. If recess or adjournment of the General Assembly prevents the return of a bill, the bill and the Governor's objections must be filed with the Secretary of State within such 60 calendar days. The Secretary of State must return the bill and objections to the originating chamber promptly upon the next meeting of the same General Assembly at which the bill can be considered.
http://www.house.mo.gov/content.aspx?info=/info/howbill.htm SIGNING BY THE GOVERNOR Bills Truly Agreed To and Finally Passed are signed in open session by the Speaker of the House and the President Pro Tem of the Senate. At the time of signing, any members may file written objections which are sent with the bill to the Governor. The Governor has fifteen days to act on a bill if it is sent to him during the legislative session; and forty-five days if the legislature has adjourned or has recessed for a thirty day period. The Governor has four options:1. Sign the bill, making it become part of Missouri law. 2. Veto the bill. In this case, the bill is returned to the General Assembly where a two-thirds vote of both houses is required to override the veto. 3. Not sign the bill. Should the Governor take no action within the prescribed time, the bill goes to the Secretary of State, who then enrolls the bill as an authentic act. It then becomes law. 4. Veto line-items in an appropriation bill. On appropriation bills only, the Governor may choose to veto selected items within the bill. The General Assembly may override this veto by a two-thirds majority of both houses.

Any bill not returned by the Governor within 60 calendar days after it is presented to him shall become law. If recess or adjournment of the General Assembly prevents the return of a bill, the bill and the Governor's objections must be filed with the Secretary of State within such 60 calendar days. The Secretary of State must return the bill and objections to the originating chamber promptly upon the next meeting of the same General Assembly at which the bill can be considered.
The General Assembly
The bill is dead because the legislature cannot override vetoes cast after adjournment.
