by John Marshall Harlan, Cheney v. Libby — Opinion of the Court
“ If the defendant had agreed, in writing, signed by himself alone, to accept current funds, and not to demand coin or legal-tender notes, and, notwithstanding such agreement, he had demanded coin or legal-tender notes, under circumstances rendering it impossible for the plaintiff to meet the demand on the day limited by the contract, would he be permitted to say that the contract was forfeited for the failure to make payment according to its provisions? ”
