Final answer:
Marbury v. Madison established the principle of judicial review, giving the courts the power to interpret and invalidate unconstitutional laws or actions.
Step-by-step explanation:
The Marbury v. Madison case was a landmark decision in the United States Supreme Court that established the principle of judicial review. Judicial review is the power of the courts to interpret and invalidate laws or governmental actions that are found to be unconstitutional.
In this case, the court held that it had the authority to review acts of Congress and determine their constitutionality. Chief Justice John Marshall, who wrote the opinion, argued that it was the duty of the court to interpret the Constitution and act as a check on the other branches of government.
Marbury v. Madison is significant because it solidified the power of the judiciary branch and established the principle of judicial review, which continues to be a fundamental aspect of the U.S. legal system today.
