Samuel Nelson, Hartshorn v. Day — Opinion of the Court
“ The difficulties are in adjusting the rights and equities of the parties in a court of law; and hence, in the States where the two systems of jurisprudence prevail, of equity and the common law, a court of law refuses to open the question of fraud in the consideration, or in the transaction out of which the consideration arises, in a suit upon the sealed instrument, but turns the party over to a court of equity, where the instrument can be set aside upon such terms as, under all the circumstances, may be equitable and just between the parties. A court of law can hold no middle course ”
