Can a court grant declaratory relief against any type of defendant in a case otherwise within the court's jurisdiction?

the United States' sovereign immunity. Whether a court may grant declaratory relief against any type of defendant in a case otherwise within the court's jurisdiction does not imply, let alone expressly state, that the United States has waived its immunity for all declaratory relief claims. Indeed, 2201 provides that the statute is "procedural only" and does not confer jurisdiction. Cal. Shock Trauma Air Rescue v. State Compensation Ins. Fund, 636 F.3d 538, 543 (9th Cir. 2011).
