Term line item veto Definition: A policy intended to address the efficiency caused by legislative logrolling by giving executive officers who have veto authority over legislation (Presidents, Governors, Mayors), the ability to veto specific sections of a legislative act rather than the entire act. With a standard veto, the executive vetoes the entire piece of legislation. With line item veto, the executive can veto only parts of the legislation while signing the rest of it into law. While a line item veto is likely to reduce logrolling, it effectively gives the executive officer more power and authority.
