H. N. Neill, West v. West, 29 S.W. 242 — Opinion of the Court (1895)
“ While this general doctrine prevails in equity as well as at law, equity sometimes exercises it jurisdiction on account of a mistake of law. If the mistake of law is not pure and simple, but is induced or accompanied by other special facts giving rise to an independent equity on behalf of the mistaken person, such as inequitable conduct of the other party, equity will interpose its aid. Even when a mistake of law is pure and simple, equity may in some cases interfere. ”
