Douglas, 458 U.S. 941 (1982), was a case in which the United States Supreme Court decided that a Nebraska statute forbidding commercial exportation of water from Nebraska was unconstitutional in that it violated the dormant commerce clause. The Supreme Court of the United States is the highest court in the United States. It has ultimate (but largely discretionary) appellate jurisdiction over all state and federal courts, and original jurisdiction over a small range of cases. The Court, which meets in the United States Supreme Court Building in Washington, D.C., consists of a chief justice and eight associate justices who are nominated by the President and confirmed by the Senate. Once appointed, justices have life tenure unless they are removed after impeachment.
