What factors made the creation of the federal judiciary controversial in the 1780's?

The federal judiciary is the branch of government that holds trials and decides cases under the nation's laws. The powers of the federal judiciary appear in Article III of the U.S. Constitution. America adopted the Constitution in 1788. Before then, the country did not have a separate judiciary. Instead Congress exercised all the powers of the nation's government.
