Prosecutors may not use peremptory challenges to dismiss jurors based on their sex. Decided April 19, 1994 (argued November 2, 1993). Opinion of the Court: Harry Blackmun → go there Dissenting: Rehnquist, Scalia. Applied: the Fourteenth Amendment → go there Topic: Discrimination based on sex. J. E. B. v. Alabama ex rel. T. B., 511 U.S. 127 (1994), is a landmark decision of the Supreme Court of the United States holding that peremptory challenges based solely on a prospective juror's sex are unconstitutional. J.E.B. extended the court's existing precedent in Batson v. Kentucky (1986), which found race-based peremptory challenges in criminal trials unconstitutional, and Edmonson v. Leesville Concrete Company (1991), which extended that principle to civil trials. As in Batson, the court found that sex-based challenges violate the Equal Protection Clause. Wiki link
