Alaska v. United States, and submerged islands
The National Park Service decided in 1998 to gradually eliminate commercial fishing in Alaska's Glacier Bay. The dispute is about whether the Feds or the State of Alaska own Alaska's submerged land in the Bay. Alaska's argument is that when Congress in 1925 declared Glacier Bay a national park, it did not mean to include the waters in the bay.
It's State sovereignty, and it has skipped the sundry and gone straight to the Supreme Court. Oral arguments are set for January 10.
