Here is the opinion and materials in Miller v. Wright.

The court’s syllabus:

Affirming the district court’s dismissal of an antitrust action brought by cigarette vendors challenging taxes imposed by virtue of the authority vested in an Indian tribe, the panel held that the district court lacked subject matter jurisdiction in light of the tribe’s sovereign immunity. The panel held that the tribe did not implicitly waive its sovereign immunity by agreeing to dispute resolution procedures nor by ceding its authority to Washington State when entering into a cigarette tax contract. The panel also held that federal antitrust law did not explicitly abrogate tribal immunity, and the Sherman Antitrust Act was not a law of general applicability vis-a-vis the tribe. The panel held that tribal officials were protected by the tribe’s sovereign immunity because they acted pursuant to the tribe’s authority. The panel also affirmed the district court’s alternative ruling that the action was barred by res judicata in light of prior litigation in state and tribal courts.
