Patchak v. Zinke, 583 U.S. ___ (2018), is a United States Supreme Court case in which the Court upheld the Gun Lake Trust Land Reaffirmation Act, which precludes federal courts from hearing lawsuits involving a particular parcel of land. Although six Justices agreed that the Gun Lake Act was constitutional, they could not agree on why. In an opinion issued by Justice Thomas, a plurality of the Court read the statute to strip federal courts of jurisdiction over cases involving the property and held that this did not violate Article III of the U.S. Constitution. In contrast, Justices Ginsburg and Sotomayor, both of whom concurred in the judgment, upheld the Act as a restoration of the government's sovereign immunity.
