interests of the Settlement Class." In re MCA, Inc. Shareholders Litigation, supra, reprinted in App. to Pet. for Cert. 73a. Cf. Phillips Petroleum Co., supra, at 812 (due process requires that "the named plaintiff at all times adequately represent the interests of the absent class members").5 Under Delaware Rule 23, as under Federal Rule of Civil Procedure 23, "[a]ll members of the class, whether of a plaintiff or a defendant class, are bound by the judgment entered in the action unless, in a Rule 23(b)(3) action, they make a timely election for exclusion." 2 H. Newberg, Class Actions § 2755, p. 1224 (1977). See also Cooper v. Federal Reserve Bank of Richmond, 467 U. S. 867, 874 (1984) ("There is of course no dispute that under elementary principles of prior adjudication a judgment in a properly entertained class action is binding on class members in any subsequent litigation"). Respondents do not deny that, as shareholders of MCA's common stock, they were part of the plaintiff class and that they never opted out; they are bound, then, by the judgment.6
5 Apart from any discussion of Delaware law, respondents contend that the settlement proceedings did not satisfy due process because the class was inadequately represented. See Brief for Respondents 34-45. Respondents make this claim in spite of the Chancery Court's express ruling, following argument on the issue, that the class representatives fairly and adequately protected the interests of the class. Cf. Prezant v. De Angelis, 636 A. 2d 915, 923 (Del. 1994) ("[The] constitutional requirement [of adequacy of representation] is embodied in [Delaware] Rule 23(a)(4), which requires that the named plaintiff 'fairly and adequately protect the interests of the class' "). We need not address the due process claim, however, because it is outside the scope of the question presented in this Court. See Yee v. Escondido, 503 U. S. 519, 533 (1992). While it is true that a respondent may defend a judgment on alternative grounds, we generally do not address arguments that were not the basis for the decision below. See Peralta v. Heights Medical Center, Inc., 485 U. S. 80, 86 (1988).
6 Respondents argue that their failure to opt out of the settlement class does not constitute consent to the terms of the settlement under traditional contract principles. Brief for Respondents 16-25. Again, the issue raised by respondents—whether the settlement could bar this suit
