Marbury v. Madison
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. Initially the case involved Secretary of State James Madison, who refused to seat four judicial appointees although they had been confirmed by the Senate.
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.
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.
Plessy v. Ferguson
was the infamous case that asserted that "equal but separate accommodations" for blacks on railroad cars did not violate the "equal protection under the laws" clause of the 14th Amendment. By defending the constitutionality of racial segregation, the Court paved the way for the repressive Jim Crow laws of the South. The lone dissenter on the Court, Justice John Marshall Harlan, protested, "The thin disguise of 'equal' accommodations...will not mislead anyone."
Brown v. Board of Education of Topeka
invalidated racial segregation in schools and led to the unraveling of de jure segregation in all areas of public life. In the unanimous decision spearheaded by Chief Justice Earl Warren, the Court invalidated the Plessy ruling, declaring "in the field of public education, the doctrine of 'separate but equal' has no place" and contending that "separate educational facilities are inherently unequal." Future Supreme Court justice Thurgood Marshall was one of the NAACP lawyers who successfully argued the case.
Gideon v. Wainwright
guaranteed a defendant's right to legal counsel. The Supreme Court overturned the Florida felony conviction of Clarence Earl Gideon, who had defended himself after having been denied a request for free counsel. The Court held that the state's failure to provide counsel for a defendant charged with a felony violated the Fourteenth Amendment's due process clause. Gideon was given another trial, and with a court-appointed lawyer defending him, he was acquitted.
New York Times v. Sullivan
extended the protection offered the press by the First Amendment. L.B. Sullivan, a police commissioner in Montgomery, Ala., had filed a libel suit against the New York Times for publishing inaccurate information about certain actions taken by the Montgomery police department. In overturning a lower court's decision, the Supreme Court held that debate on public issues would be inhibited if public officials could sue for inaccuracies that were made by mistake. The ruling made it more difficult for public officials to bring libel charges against the press, since the official had to prove that a harmful untruth was told maliciously and with reckless disregard for truth.
Miranda v. Arizona
was another case that helped define the due process clause of the 14th Amendment. At the center of the case was Ernesto Miranda, who had confessed to a crime during police questioning without knowing he had a right to have an attorney present. Based on his confession, Miranda was convicted. The Supreme Court overturned the conviction, ruling that criminal suspects must be warned of their rights before they are questioned by police. These rights are: the right to remain silent, to have an attorney present, and, if the suspect cannot afford an attorney, to have one appointed by the state. The police must also warn suspects that any statements they make can be used against them in court. Miranda was retried without the confession and convicted.
Roe v. Wade
legalized abortion and is at the center of the current controversy between "pro-life" and "pro-choice" advocates. The Court ruled that a woman has the right to an abortion without interference from the government in the first trimester of pregnancy, contending that it is part of her "right to privacy." The Court maintained that right to privacy is not absolute, however, and granted states the right to intervene in the second and third trimesters of pregnancy.
Regents of the University of California v. Bakke
imposed limitations on affirmative action to ensure that providing greater opportunities for minorities did not come at the expense of the rights of the majority. In other words, affirmative action was unfair if it lead to reverse discrimination. The case involved the University of Calif., Davis, Medical School and Allan Bakke, a white applicant who was rejected twice even though there were minority applicants admitted with significantly lower scores than his. A closely divided Court ruled that while race was a legitimate factor in school admissions, the use of rigid quotas was not permissible.
Grutter v. Bollinger
upheld the University of Michigan Law School's consideration of race and ethnicity in admissions. In her majority opinion, Justice O'Connor said that the law school used a "highly individualized, holistic review of each applicant's file." Race, she said, was not used in a "mechanical way." Therefore, the university's program was consistent with the requirement of "individualized consideration" set in 1978's Bakke case. "In order to cultivate a set of leaders with legitimacy in the eyes of the citizenry, it is necessary that the path to leadership be visibly open to talented and qualified individuals of every race and ethnicity," O'Connor said. However, the court ruled that the University of Michigan's undergraduate admissions system, which awarded 20 points to black, Hispanic, and American-Indian applicants, was "nonindividualized, mechanical," and thus unconstitutional.
Schenck v. U. S.
Unanimously upheld the Espionage Act of 1917 which declared that people who interfered with the war effort were subject to imprisonment; declared that the 1st Amendment right to freedom of speech was not absolute; free speech could be limited if its exercise presented a "clear and present danger."
Dartmouth College v. Woodward
New Hampshire had attempted to take over Dartmouth College by revising its colonial charter. The Court ruled that the charter was protected under the contract clause of the U. S. Constitution; upholds the sanctity of contracts.
Cherokee Nation v. Georgia
"The conditions of the Indians in relation to the United States is perhaps unlike that of any two people in existence," Chief Justice John Marshall wrote, "their relation to the United States resembles that of a ward to his guardian. . .(they were a) domestic dependent nation." Established a "trust relationship" with the tribes directly under federal authority.
Commonwealth v. Hunt
Declared that labor unions were lawful organizations and that the strike was a lawful weapon.
