<P> Marbury was the point at which the Supreme Court adopted a monitoring role over government actions . After the Court exercised its power of judicial review in Marbury, it avoided striking down a federal statute during the next fifty years . The court would not do so again until Dred Scott v. Sandford, 60 U.S. (19 How .) 393 (1857). </P> <P> However, the Supreme Court did exercise judicial review in other contexts . In particular, the Court struck down a number of state statutes that were contrary to the Constitution . The first case in which the Supreme Court struck down a state statute as unconstitutional was Fletcher v. Peck, 10 U.S. (6 Cranch) 87 (1810). </P> <P> In a few cases, state courts took the position that their judgments were final and were not subject to review by the Supreme Court . They argued that the Constitution did not give the Supreme Court the authority to review state court decisions . They asserted that the Judiciary Act of 1789, which provided that the Supreme Court could hear certain appeals from state courts, was unconstitutional . In effect, these state courts were asserting that the principle of judicial review did not extend to allow federal review of state court decisions . This would have left the states free to adopt their own interpretations of the Constitution . </P> <P> The Supreme Court rejected this argument . In Martin v. Hunter's Lessee, 14 U.S. (1 Wheat .) 304 (1816), the Court held that under Article III, the federal courts have jurisdiction to hear all cases arising under the Constitution and laws of the United States, and that the Supreme Court has appellate jurisdiction in all such cases, whether those cases are filed in state or federal courts . The Court issued another decision to the same effect in the context of a criminal case, Cohens v. Virginia, 19 U.S. (6 Wheat .) 264 (1821). It is now well established that the Supreme Court may review decisions of state courts that involve federal law . </P>
