What is the test for making out a prima facie case of discrimination amounting to a denial of equal protection?

Brief, p. 46 (footnote omitted). The brief discusses the three elements set out in Castaneda v. Partida, 430 U.S. 482, 494, 97 S.Ct. 1272, 1280, 51 L.Ed.2d 498 (1977), required to make out a prima facie case of jury discrimination amounting to a denial of equal protection: (1) the court must determine whether the excluded group is cognizable; (2) the court must determine whether underrepresentation of the group is substantial; (3) the court must determine whether the method of jury selection is susceptible of abuse or not racially neutral. It discusses the facts that meet these criteria. A prima facie case of discrimination amounting to a denial of equal protection follows from meeting these criteria. A litigant is not required to incant the magic word "intentional."
