Here is the opinion. From the syllabus:
The panel affirmed the district court’s summary judgment in a treaty fishing rights case in which the Tulalip Tribes sought a determination of the scope of the Suquamish Indian Tribe’s usual and accustomed fishing grounds and stations.
The Tulalip Tribes invoked the district court’s continuing jurisdiction as provided by a permanent injunction entered in 1974. The panel affirmed the district court’s conclusion that certain contested areas were not excluded from the Suquamish Tribe’s usual and accustomed fishing grounds and stations, as determined by the district court in 1975.
