These cases present several issues arising out of petitioners\u27 action against respondents for alleged racial discrimination in employment and provision of services by the North Carolina Agricultural Extension Service (Extension Service). The District Court declined to certify various proposed classes and, after a lengthy trial, entered judgment for respondents in all respects, finding that petitioners had not carried their burden of demonstrating that respondents had engaged in a pattern or practice of racial discrimination. The District Court also ruled against each of the individual plaintiff\u27s discrimination claims. The Court of Appeals affirmed. 751 F. 2d 662 (CA4 1984)
