David Josiah Brewer,
Mississippi Mills v. Cohn — Opinion of the Court
“ It is well settled that the jurisdiction of the federal courts, sitting as courts of equity, is neither enlarged nor diminished by state legislation. Though by it all differences in forms of action be abolished, though all remedies be administered in a single action at law, and so far, at least, as form is concerned, all distinction between equity and law be ended, yet the jurisdiction of the federal court, sitting as a court of equity, remains unchanged. ”
