The 2013 United States versus Windsor case, in which justices ruled the Defense of Marriage Act unconstitutional, is one of the Supreme Court's most iconic cases, explains the Cable News Network. Other significant cases include the 1973 Roe versus Wade case and the 1964 New York Times versus Sullivan case.
The 1974 United States versus Nixon case, in which the Supreme Court ruled that U.S. presidents were not above the law, is also significant, according to CNN. The case pitted President Nixon, who sought to use executive privilege to stop the release of certain recordings relating to the Watergate scandal, against special prosecutor Leon Jaworski, who was investigating the affair. On July 24, 1974, the court ruled against Nixon, and he resigned on Aug. 8, 1974.
The 1954 Brown versus Board of Education case, which addressed racial segregation in U.S. public school systems, is also significant, according to CNN. A nearby whites-only school had denied admission to third grader Linda Brown, forcing her to attend a blacks-only institution farther away. The Supreme Court declared that such discrimination violated the Equal Protection Clause of the 14th Amendment and ruled unanimously in favor of Brown.
Other significant cases include the 1978 Regents of the University of California versus Bakke, in which the Supreme Court ruled that race should not be the sole consideration in college admissions, and the 1966 Miranda versus Arizona case, in which the Court established protections against self-incrimination, explains CNN.
