Shannon Russell, as representative of Rose Anne Eaton’s estate, seeks to apply the findings in Engle v. Liggett Group, Inc., 945 So.2d 1246 (Fla. 2006) (per curiam), 1 to prove that Marlboro cigarettes were defectively designed. Phillip Morris USA, Inc., the manufacturer of Marlboro cigarettes, argues that Russell cannot rely on Engle because Eaton is not a member of the Engle class and that under Florida law collateral estoppel cannot be applied in this case. After reviewing the briefs and the case law, we affirm the district court’s grant of summary judgment in favor of Phillip Morris.

Russell filed a wrongful death action on behalf of her mother alleging that her mother died of lung cancer caused by a lifetime of smoking Marlboro cigarettes. Eaton’s lung cancer was not diagnosed until 2006. Russell admitted to the district court that she could not prove her claims without relying on Engle.

We review a district court’s grant of summary judgment de novo, viewing all evidence and drawing all reasonable inferences in favor of the non-moving party. Owen v. I.C. Sys., Inc., 629 F.3d 1263,1270 (11th Cir. 2011). Summary judgment is appropriate where “there is no genuine issue as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(a).

We give preclusive effect to state court judgments when two conditions are met: “(1) the courts of the state from which the judgment emerged would do so themselves; and (2) the litigants had a full and fair opportunity to litigate their claims and the prior state proceedings otherwise satisfied the applicable requirements of due process.” Quinn v. Monroe Cnty., 330 F.3d 1320, 1329 (11th Cir. 2003). Florida law requires mutuality of parities in order to apply collateral estoppel. E.C. v. Katz, 731 So.2d 1268, 1269 (Fla. 1999) (per curiam). “[UJnless both parties are bound by the prior judgment, neither may use it in a subsequent action.” Id. (quoting Stogniew v. McQueen, 656 So.2d 917, 919 (Fla. 1995)).

Eaton is not a member of the Engle class and cannot now seek to join it because the Florida Supreme Court held that the cut-off date for inclusion was November 21, 1996. Engle, 945 So.2d at 1255. Thus, Eaton was not a party to the Engle case and cannot now rely on the findings in that case under Florida law. See R.J. Reynolds Tobacco Co. v. Brown, 70 So.3d 707, 715 (Fla.App. 2011) (finding that plaintiffs must prove that they are a member of the Engle class). Because Russell con *844 ceded that she could not prove her claim without Engle and she is barred from relying on Engle, we affirm the district court’s grant of summary judgment in favor of Phillip Morris.

AFFIRMED.
