e, governments derive “their just powers from the consent of the governed.” Locke also pioneered the idea of the separation of powers, and he separated the powers into an executive and a legislature. The French political philosopher Baron de Montesquieu, another major intellectual influence on the Constitution, further developed the concept of separation of powers in his treatise The Spirit of the Laws (1748), which was highly regarded by the framers of the U.S. Constitution. Montesquieu’s basic contention was that those entrusted with power tend to abuse it; therefore, if governmental power is fragmented, each power will operate as a check on the others. In its usual operational form, one branch of government (the legislative) is entrusted with making laws, a second (the executive) with executing them, and a third (the judiciary) with resolving disputes in accordance with the law.
Based on the theory of Baron de Montesquieu and John Locke, the framers carefully spelled out the independence of the three branches of government: executive, legislative, and judicial. At the same time, however, they provided for a system in which some powers should be shared: Congress may pass laws, but the president can veto them; the president nominates certain public officials, but Congress must approve the appointments; and laws passed by Congress as well as executive actions are subject to judicial review. Thus the separation of powers is offset by what are called checks and balances.
2. Separation of Powers among Three Governmental Branches
Separation of powers devised by the framers of the U.S. Constitution serves the goals: to prevent concentration of power and provide each branch with weapons to fight off encroachment by the other two branches. As James Madison argued in the Federalist Papers (No.51), “Ambition must be made to counteract ambition.” Clearly, the system of separated powers is not designed to maximize efficiency; it is designed to maximize freedom. In the Constitution of the United States, the Legislative, composed of the House and Senate, is set up in Article 1; the Executive, composed of the President, Vice-President, and the Departments, is set up in Article 2; the Judicial, composed of the federal courts and the Supreme Court, is set up in Article 3. Each of these branches has certain powers, and each of these powers is limited.
The First Article of the U.S. Constitution says, “All legislative powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.” These words clearly define the most important power of Congress: to legislate for the United States. At the same time, the framers granted some specific powers to Congress. Congress has the power to impeach both executive officials and judges. The Senate tries all impeachments. Besides, Congress can override a Presidential veto. Congress may also influence the composition of the judicial branch. It may establish courts inferior to the Supreme Court and set their jurisdiction. Furthermore, Congress regulates the size of the courts. Judges are appointed by the President with the advice and consent of the Senate. The compensation of executive officials and judges is determined by Congress, but Congress may not increase or diminish the compensation of a President, or diminish the compensation of a judge, during his term in office. Congress determines its own members’ emoluments as well. In short, the main powers of the Legislature include: Legislating all federal laws; establishing all lower federal courts; being able to override a Presidential veto; being able to impeach the President as well as other executive officials.
Executive power is vested in the President by the U.S. Constitution in Article 2. The principal responsibility of the President is to ensure that all laws are faithfully carried out. The President is the chief executive officer of the federal government. He is the leader of the executive branch and the commander in chief of the armed forces. He has the power to make treaties w
