United States v. Washington (2022)

United States v. Washington (2022) refers to a specific legal case heard by the United States Supreme Court. While the citation format suggests it involved a dispute between the United States government and the state of Washington, without further context (e.g., volume and page number of the official legal reporter where the decision is published) it's difficult to ascertain the precise subject matter or holding of the case. Court cases are typically cited in the format: Party A v. Party B, Volume number Reporter abbreviation Page number (Court date).

Therefore, locating the actual case information in legal databases like Westlaw, LexisNexis, or Bloomberg Law is necessary to fully understand the issues presented and the Supreme Court's decision. Possible areas of law this case might have involved given the parties could range from environmental law, treaty rights involving Native American tribes (given Washington's geographic location and significant Native American population), or disputes over federal versus state authority. However, these are simply possible areas and require verification with the official case record.
