why is the marbury case important in the history of the supreme court
Marbury v. Madison, arguably the most important case in Supreme Court history, was the first U.S. Supreme Court case to apply the principle of judicial review -- the power of federal courts to void acts of Congress in conflict with the Constitution.ut, by his timely assertion of judicial review, the Court began its ascent as an equal branch of government -- an equal in power to the Congress and the president. Throughout its long history, when the Court needed to affirm its legitimacy, it has cited Marshall's opinion in Marbury v. Madison.
