Text: The District Court had subject-matter jurisdiction over these actions under 42 U.S.C. § 2210(n)(2) because this is a public liability action arising out of a nuclear incident in the Western District of Pennsylvania. This Court has jurisdiction over Plaintiffs’ appeals under 28 U.S.C. § 1291. Plaintiffs argue that we did not have jurisdiction over Defendants’ cross-appeal relating to the District Court’s denial of their Daubert motion regarding Melius because Defendants are not aggrieved by that denial. As the Supreme Court observed in Deposit Guaranty National Bank v. Roper, “Ordinarily, only a party aggrieved by a judgment or order of a district court may exercise the statutory right to appeal therefrom. A party who receives all that he has sought generally is not aggrieved by the judgment affording the relief and cannot appeal from it.” 445 U.S. 326, 333 (1980); see also Nanavati v. Burdette Tomlin Mem’l Hosp., 857 F.2d 96, 102 (3d Cir. 1988) (“Because they are completely satisfied with the final judgment and object only to interlocutory rulings of the district court, we lack jurisdiction over their appeal.”). We need not determine whether we have jurisdiction. We simply follow Third Circuit practice and dismiss Defendants’ cross-appeals as “superfluous.” Smith v. Johnson & Johnson, 593 F.3d 280, 283 n.2 (3d Cir. 2010) (“Yet a party, without taking a cross-appeal, 30 may urge in support of an order from which an appeal has been taken any matter appearing in the record, at least if the party relied on it in the district court.”). As such, we consider the parties’ Daubert arguments to concern causation only as an “alternate ground for affirmance.” Nanavati, 857 F.2d at 102. Accordingly, we have disregarded Defendants’ reply brief in support of their cross-appeal.
