Marshall v. Cook

Petition for certiorari denied on October 6, 2025

Docket No. Op. Below Argument Opinion Vote Author Term
25-4 5th Cir. N/A N/A N/A N/A OT 2025

Issue: Whether diversity jurisdiction may be created by having one diverse co-trustee bring the lawsuit, strategically excluding all nondiverse co-trustees as parties, or instead the citizenship of the nondiverse, nonparty co-trustees must be counted because they all are “real parties to the controversy” by virtue of their equally shared powers to hold and manage trust property and to sue and be sued in their own names—which here would destroy diversity.
