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

The outcome of the Supreme Court case Marbury v. Madison was significant in that it established the principle of judicial review. This ruling, delivered in 1803 by Chief Justice John Marshall, asserted the power of the Supreme Court to review and nullify government actions that are found to be in conflict with the Constitution. This means that the Court has the authority to invalidate laws and executive actions that it determines do not comply with the Constitution, thereby reinforcing the system of checks and balances among the branches of government. This foundational principle has since become a cornerstone of the American legal system, allowing the judiciary to serve as a critical check on legislative and executive power. The impact of this case cements the judiciary's role in interpreting the law and upholding constitutional governance.
