Can a federal court order an injunction preventing future litigation in a state court?

This court declines to grace appellant's contentions with a point-by-point analysis of his allegations. His brief has shown no facts nor any basis in law for overturning the order and judgment of the district court. Appellant essentially seems to think that a federal court cannot enjoin future action in state courts. This court has found such an injunction may be available in a proper case. See Zippel v. Halliburton Co., 861 F.2d 565, 568-70 (9th Cir.1988) (injunction preventing future litigation in state courts is proper).
