What was the effect of the US Supreme Court case Marbury v Madison?

Answer 1

The most important effect of Marbury v. Madison, (1803), is that it affirmed the Supreme Court's right of judicial review and set a precedent for future cases. Judicial review is the power of the Court to evaluate laws relevant to cases before the court to determine their constitutionality, and to nullify (overturn) any they find unconstitutional.

In Marbury, the Supreme Court decided Section 13 of the Judiciary Act of 1789 was unconstitutional because Congress had overreached its authority by granting the Court the right to issue all writs of mandamus, which contradicted the language of Article III of the Constitution.
