Answer:
Printz v. United States, 521 U.S. 898 (1997), was a United States Supreme Court case in which the Court held that certain interim provisions of the Brady Handgun Violence Prevention Act violated the Tenth Amendment to the United States Constitution.
Marbury v. Madison (1803) was the first instance in which a law passed by Congress was declared unconstitutional. The decision greatly expanded the power of the Court by establishing its right to overturn acts of Congress, a power not explicitly granted by the Constitution.
McCulloch v. Maryland upheld the right of Congress to create a Bank of the United States, ruling that it was a power implied but not enumerated by the Constitution. The case is significant because it advanced the doctrine of implied powers, or a loose construction of the Constitution. The Court, Chief Justice John Marshall wrote, would sanction laws reflecting “the letter and spirit” of the Constitution.

Gibbons v. Ogden defined broadly Congress's right to regulate commerce. Aaron Ogden had filed suit in New York against Thomas Gibbons for operating a rival steamboat service between New York and New Jersey ports. Ogden had exclusive rights to operate steamboats in New York under a state law, while Gibbons held a federal license. Gibbons lost the case and appealed to the U.S. Supreme Court, which reversed the decision. The Court held that the New York law was unconstitutional, since the power to regulate interstate commerce, which extended to the regulation of navigation, belonged exclusively to Congress. In the 20th century, Chief Justice John Marshall's broad definition of commerce was used to uphold civil rights.
1857
Dred Scott v. Sandford was a highly controversial case that intensified the national debate over slavery. The case involved Dred Scott, a slave, who was taken from a slave state to a free territory. Scott filed a lawsuit claiming that because he had lived on free soil he was entitled to his freedom. Chief Justice Roger B. Taney disagreed, ruling that blacks were not citizens and therefore could not sue in federal court. Taney further inflamed antislavery forces by declaring that Congress had no right to ban slavery from U.S. territories.
