The legislature plays a crucial role in the ratification of treaties, as it is typically required to approve international agreements negotiated by the executive branch. This process ensures that the interests of the nation are represented through checks and balances, allowing for scrutiny of the treaty's implications. During ratification, legislators can debate the treaty’s potential impact on domestic law, maintain national sovereignty, and assess long-term implications on foreign relations. The legislative body's involvement reflects the democratic principles of transparency and accountability in foreign policy decisions.
