Final answer:
The statement about Marbury v. Madison being overturned by United States v. Stevens in 2010 is false. Marbury v. Madison established the Supreme Court's power of judicial review, and this principle stands as a cornerstone of the American judicial system today.
Step-by-step explanation:
The case of Marbury v. Madison is significant today because it established the Supreme Court's power of judicial review. This landmark decision in 1803 asserted that the Court had the authority to nullify Congressional acts by declaring them unconstitutional, which serves as a vital check on the powers of the other branches of government. Contrary to the statement in the question, this case was not overturned by United States v. Stevens in 2010; rather, Marbury v. Madison remains a fundamental principle of the U.S. legal system. The significance of the case is that it solidified the Court's role in the system of checks and balances and ensured the judiciary's place as an independent branch capable of restraining the other branches of government. The ability to deem legislative and executive actions unconstitutional is central to the functioning of the American government, ensuring that no law or executive action can supersede the Constitution.
