Who has the authority to sign a bill into law in Missouri?

In Missouri, the authority to sign a bill into law is vested in the Governor. This role is established by the Missouri Constitution, which outlines the legislative process. After a bill has been passed by both houses of the General Assembly, it is presented to the Governor, who has the option to sign it, allowing it to become law. Alternatively, the Governor can veto the bill or allow it to become law without a signature by not acting on it within a specified timeframe.

This power is significant, as it allows the executive branch to exercise a check on the legislative process, ensuring that the Governor has the ability to influence the laws that govern the state. This function differs from the roles of the Lieutenant Governor, Attorney General, and Speaker of the House, who do not possess the authority to sign legislation into law. Their responsibilities are centered around other areas of governance, enforcement of law, and legislative leadership, respectively.
