Stephen Johnson Field,
Life Insurance Company v. Bangs…
“ A suit in equity will not lie to give effect to defences against a claim when they might have been fully set up in an action at law. There must have been some fraud practised upon the court or some unconscientions advantage taken of the defendant without any fault or negligence on his part; or there must be some newly discovered evidence which could not have been obtained at the trial, and which, if produced, would have changed the result, before a court of equity will interfere with the judgment rendered or the contract upon which it was recovered. ”
