What defines landmark supreme court cases

The correct answer is C) They result in significant changes in the way laws are interpreted.

The Supreme Court plays a critical role in American society, as this branch of the federal government determines whether laws are constitutional or unconstitutional. This has a lasting impact on all American citizens, as the Supreme Court is the highest court in the United States.

For example, one of the most significant court cases of the 20th century was the famous Brown vs. Board of Education Supreme Court case. In this case, the Supreme Court justices ruled that "separate but equal" facilities for black and white students was a clear violation of the 14th amendment and the Equal Protection Clause. This change in interpretation resulted in the ending of segregated public schools in America.
