It was while debating the separation of powers between the legislative and executive departments that delegates to the 1787 Constitutional Convention established the parameters for the national judiciary. Creating a "third branch" of government was a novel idea; in the English tradition, judicial matters had been treated as an aspect of royal (executive) authority. Early on, the delegates who were opposed to having a strong central government argued that national laws could be enforced by state courts, while others, including James Madison, advocated for a national judicial authority consisting of various tribunals chosen by the national legislature. It was also proposed that the judiciary should have a role in checking the executive's power to veto or revise laws. In the end, the framers compromised by sketching only a general outline of the judiciary, vesting federal judicial power in "one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish." They delineated neither the exact powers and prerogatives of the Supreme Court nor the organization of the judicial branch as a whole.
