What role does the supreme court play in changing the constitution?

It can tell a President that his actions are not allowed by the Constitution. It can tell Congress that a law it passed violated the U.S. Constitution and is, therefore, no longer a law. It can also tell the government of a state that one of its laws breaks a rule in the Constitution.

The Supreme Court is the final judge in all cases involving laws of Congress, and the highest law of all — the Constitution.

The Supreme Court, however, is far from all-powerful. Its power is limited by the other two branches of government. The President nominates justices to the court. The Senate must vote its approval of the nominations. The whole Congress also has great power over the lower courts in the federal system. District and appeals courts are created by acts of Congress. These courts may be abolished if Congress wishes it.

The Supreme Court is like a referee on a football field. The Congress, the President, the state police, and other government officials are the players. Some can pass laws, and others can enforce laws. But all exercise power within certain boundaries. These boundaries are set by the Constitution. As the "referee" in the U.S. system of government, it is the Supreme Court's job to say when government officials step out-of-bounds.

the united states constitution is the supreme law of the united states. the constitution, originally comprising seven articles, delineates the national frame of government. its first three articles embody the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral congress; the executive, consisting of the president; and the judicial, consisting of the supreme court and other federal courts. articles four, five and six embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment. article seven establishes the procedure subsequently used by the thirteen states to ratify it. it is regarded as the oldest written and codified national constitution in force.
