For an association to have standing to sue for its members, it must show that (a) its members would otherwise have standing to sue in their own right; (b) the interests it seeks to protect are germane to the organization’s purpose; and (c) neither the claim asserted nor the relief requested requires the participation of individual members in the lawsuit. Here, all three requirements were met in a union suit for damages its members suffered because defendants’ wrongful conduct delayed approval of a collective bargaining agreement that raised union members’ wages. The association proved the amount of damages suffered because of the delay through lay and expert witnesses without calling a single union member to the stand, thus showing that the union members did not need to be made parties for the claims or relief requested. The other two requirements were undisputed.
