The constitution of the United States set up a set of checks and balances among the three branches of government. The Legislative, Executive and Judicial powers constitute the structure of the american government, and they have power to check each other's way of work.

This is a clear check limit used against the legislative power, that is the congress. But on the other hand, the power is balanced because the members of the Supreme Court are appointed by the President of the country (the Executive power), and to be appointed they have to be approved by the Congress.
