“It is hornbook law, based on 66 years of Supreme Court precedent, that complete diversity is required only between the named plaintiffs and the named defendants in a federal class action. 13B C. Wright, A. Miller & E. Cooper, Federal Practice and Procedure § 3606, at 424 (2d ed. 1986) ("[t]he courts look only to the citizenship of the representative parties in a class action"). As the Supreme Court noted in Snyder v. Harris, 394 U.S. 332 (1969): Under current doctrine, if one member of a class is of diverse citizenship from the class' opponent, and no nondiverse members are named parties, the suit may be brought in federal court even though all other members of the class are citizens of the same State as the defendant and have nothing to fear from trying the lawsuit in the courts of their own State. . . .” In re Agent Orange Product Liability Litigation MDL NO. 381, 818 F.2d 145, 162 (2d Cir. 1987)
