súrers claimed that the relationship between the coverage that they provided and the coverage that INA provided concerning the 1960-65 policies made INA an indispensable party to the federal suit.
On October 20,1994, without comment, the district court granted the London Insurers’ Motion to Dismiss. Koppers filed a Motion for Reconsideration, but the district court denied that motion on March 24, 1995. As a result, Koppers brought suit against the London Insurers relating to the 1960-65 policies by adding them as defendants in the state court action against INA.
After the initial dismissal of Koppers’ claims against the London Insurers pertaining to the 1960-65 policies, all of the defendant insurers except for the London Insurers settled with Koppers before trial. Thus, following the dismissal and settlement, the only remaining claims in the case were those against the London Insurers for the period from the 1940s to 1959 and 1966 to the 1970s. See Koppers, 98 F.3d at 1444.
In April-May 1995, the district court conducted a trial over Koppers’ claims against the remaining defendants (the London Insurers) but the court limited the scope of that trial to policies that provided coverage from late 1953 until January 1960. The district court further limited the scope of the trial to only eighteen of the contaminated sites. Following a three week trial, the jury awarded Koppers $70 million. See id.
On July 20, 1995, pursuant to Rule 54(b), the district court certified as final for interlocutory appeal the part of its judgment relating to the claims litigated at the jury trial, noted above. Although Koppers cross-appealed, it did not challenge the district court’s decision to dismiss the 1960-65 policy claims against the London Insurei».
On appeal, in reversing the district court’s method of apportioning liability, we commented that
the district court would not need to determine whether the non-settling pre-1971 policies were triggered because the London Insurers concede — against their interests — that all of Koppers’ policies up to 1971 (the date from which pollution exclusion clauses have appeared in all the policies) were triggered.
Id. at 1456. In addition, in a footnote, we suggested that INA was not a necessary party for a proper adjudication of the claims involved in this dispute:
We recognize that some of Koppers’ insurers are not part of this action because they are non-diverse with the plaintiff. Under [Gould Inc. v. Continental Cas. Co., 401 Pa.Super. 219, 585 A.2d 16 (1991)], however, these insurers need not participate in the case in order for the district court to determine their apportioned shares of liability for purposes of reducing the judgment against the London Insurers. See 585 A.2d at 19 (stating that court need only look at policies’ terms and limits). Of course, any determination that these policies were triggered would not be binding or preclusive against the absent insurers in future litigation because they are not parties here. We note also that the London Insurers’ interests are aligned with those of the absent insurers: each would like to prove that the absent insurers’ policies were not triggered. For the London Insurers, such a determination would increase the settling insurers’ shares (thereby decreasing the London Insurers’ liability), and the absent insurers would naturally like to avoid a determination of liability in the first place.
Id. n. 21.
Prompted by our intimation that INA was not an indispensable party, Koppers moved to reinstate the dismissed claims pertaining to the 1960-65 policies. Essentially, then, Koppers requested the district court to reconsider its earlier decision which had dismissed the claims pertaining to the 1960-65 policies on the grounds that INA was an indispensable party. On June 10, 1997, the district court denied this motion from the bench, ruling:
I think that’s the law of the case[.] It could have been appealed at the time the rest of this case went up and therefore, I’m going to deny the motion to reinstate any
