The US Supreme Court did what in Piscataway Board of Education v. Taxman, 521 U. S. 1117, 117 S. Ct. 2506 (1997)?

The case was never heard in the United States Supreme Court.

Explanation:

The board of education of Piscataway High School, New Jersey desired to remove one teaching position from the Business Education department. A hindrance to this was the fact that the two teachers being considered had indefinite appointments, and were equal in seniority. According to the state law, tenured teachers can be relieved of their duties in reverse order of seniority. Either Sharon Taxman, a white teacher, or Debra Williams an African-American teacher were to be relieved of their positions.

Taxman was chosen because African-Americans were a minority. Taxman contested this in the court. The case was never heard at the U.S Supreme court because some civil rights group wanted the case to be settled out of court. The United States Court of Appeal ruled in favor of Taxman.
