The executive checks the excesses of the legislature through

The executive branch of government has the power to check the excesses of the legislative branch through "assent to bills." This means that before a bill passed by the legislature becomes law, the executive (usually the president or governor) must give their approval by signing it. If the executive believes the bill is unconstitutional or inappropriate, they may refuse to sign it and veto the bill. This veto power allows the executive to prevent the legislature from passing laws that they consider to be harmful or unnecessary. By using their assent or veto power, the executive branch can help ensure that the legislature does not exceed its authority or act against the interests of the nation.
