John Marshall Harlan II,
United States v. Louisiana — Opinion of the Court
“ A land boundary between two States is an easily understood concept. It marks the place where the full sovereignty of one State ends and that of the other begins. The concept of a boundary in the sea, however, is a more elusive one. The high seas, as distinguished from inland waters, are generally conceded by modern nations to be subject to the exclusive sovereignty of no single nation. ”
