A "legislative veto" is a mechanism that allows a legislative body to reject or nullify executive actions, such as regulations or decisions made by an administrative agency. This tool provides a check on executive power and is intended to ensure that legislative intent is respected in the implementation of laws. While some argue that legislative vetoes enhance accountability, others contend that they can complicate governance. The constitutionality of legislative vetoes has been challenged in courts, raising questions about the balance of power among branches of government.
