Donald Roe Ross, Mosley v. General Motors Corp.…
“ The right to relief here depends on the ability to demonstrate that each of the plaintiffs was wronged by racially discriminatory policies on the part of the defendants General Motors and the Union. The discriminatory character of the defendants' conduct is thus basic to each plaintiff's recovery. The fact that each plaintiff may have suffered different effects from the alleged discrimination is immaterial for the purposes of determining the common question of law or fact. Thus, we conclude that the second requisite for joinder under Rule 20 (a) is also met by the complaint. ”
