The proposed Senate Joint Resolution 11 seeks to amend the Wisconsin Constitution to limit the governor's partial veto authority specifically regarding appropriation bills. Under the new amendment, the governor would only be allowed to reject entire sections of an appropriation bill that can stand alone as complete laws and to reduce appropriations within the bill. This change aims to clarify and restrict the current partial veto powers, which have been subject to interpretation and legal challenges, including a recent Wisconsin Supreme Court case that imposed additional limitations.

Currently, the governor's partial veto power is constrained only by prohibitions against creating new words or sentences through selective vetoing of letters or parts of sentences. The proposed amendment would expand these restrictions, ensuring that the governor cannot exercise partial vetoes in any manner other than as specified. For this constitutional amendment to take effect, it must be approved by two consecutive legislatures and subsequently ratified by the electorate.
