What was the outcome of the Supreme Court case Marbury v. Madison?

The outcome of the Supreme Court case Marbury v. Madison is significant because it established the principle of judicial review, which allows the Supreme Court to declare laws and actions of Congress and the President unconstitutional. This landmark decision was made in 1803 under Chief Justice John Marshall, who asserted that the Constitution is the supreme law of the land and that it is the role of the judiciary to interpret it. By declaring that a portion of the Judiciary Act of 1789 was unconstitutional, the Court effectively empowered itself to review and invalidate actions that contravene the Constitution. This case set a crucial precedent for the balance of power among the branches of government, solidifying the judiciary's role as a check on legislative and executive actions.

In the context of the other options, nullifying a Congressional act directly relates to the judicial review aspect but does not fully encompass the broader significance of the ruling itself. Expanding voting rights and setting limitations on presidential power are not relevant outcomes of this case. Marbury v. Madison primarily focused on the judiciary's power and its function within the government's framework, making the establishment of judicial review its most important outcome.
