Republic of Philippines v. Pimentel, Temporary Administrator of Estate of Pimentel, Deceased

Summary

Justice Kennedy's opinion held that the interpleader action must be dismissed under Rule 19(b) because proceeding without the immune Republic of the Philippines and its Presidential Commission on Good Governance would prejudice their nonfrivolous claims to the disputed assets. The lower courts improperly discounted sovereign immunity and adjudicated the absent sovereign entities' claims on their merits. Arelma and Philippine National Banc had standing to seek procedural relief even though they had not sought review of the adverse merits ruling; the Court therefore did not decide whether the immune entities themselves could appeal. Justice Stevens, writing separately without a joiner, agreed that jurisdiction existed and that reversal was warranted, but favored further proceedings, potentially including a stay or reassignment, rather than mandatory dismissal. Justice Souter, also writing without a joiner, joined all but Parts IV-B and V and would have vacated and remanded for a reasonable stay awaiting the Philippine court's ruling, with further district-court proceedings assigned to a different judge.
