The oversight function is performed by the legislature. This means that the responsibility for checking and monitoring the actions of the executive branch of government, such as the President or Prime Minister, is the duty of the legislative branch, which is typically composed of elected representatives. The oversight function helps to ensure that the executive branch is acting in accordance with the law and in the best interests of the citizens. This includes monitoring the allocation of funds, the implementation of policies, and the conduct of government officials. The legislative branch can use a variety of tools to carry out its oversight function, including holding hearings, conducting investigations, and requesting information and reports from the executive branch. Ultimately, the oversight function serves as a crucial check and balance on the power of the executive branch, helping to maintain the democratic principles of transparency and accountability.
