Answer 1

The correct answer is: It created the idea of judicial review.

Marbury v Madison is widely considered a landmark Supreme Court case because it established the principle of judicial review. Judicial review is the power of the courts to determine the constitutionality of legislative and executive actions. In this case, Chief Justice John Marshall declared that the Supreme Court had the authority to interpret the Constitution and had the power to invalidate laws that were found to be unconstitutional. This decision significantly strengthened the role of the judiciary branch and established the principle of checks and balances in the American system of government.
