Next, the Court of Appeals acknowledged that on appeal both parties had requested judicial notice of facts contained within the record of a parallel proceeding, involving different plaintiffs, in a Nigerian Court. The Court of Appeals referred to the Nigerian litigation as "Zango v. Pfizer" ("Zango litigation"). The "Zango litigation" had recently been dismissed in Nigeria. The court declined to take judicial notice of the "Zango litigation", instead opting to vacate the district court's dismissal on grounds of "forum non conveniens" and remanding the case to the district court to consider the implications of the "Zango litigation" on its "forum non conveniens" analysis.
