Legislative oversight is the process by which a legislative body, such as a Congress or Parliament, monitors and reviews the actions of the executive branch and its agencies. This oversight ensures that laws are implemented effectively and that government officials are held accountable for their actions. It can involve hearings, investigations, and the review of budgets and policies. Through legislative oversight, lawmakers can identify issues, prevent misuse of power, and ensure that public resources are used efficiently. This process helps maintain a system of checks and balances, promoting transparency and accountability within the government.
