Fred M. Vinson,
Pope v. Atlantic Coast Line Railroad Company…
“ Congress has limited our power to review judgments from state courts lest the Court's jurisdiction be exercised in piecemeal proceedings to render advisory opinions. Were our reviewing power not limited to 'final' judgments, litigants would be free to come here and seek a decision on federal questions which, after later proceedings, might subsequently prove to be unnecessary and irrelevant to a complete disposition of the litigation. ”
