The enactment will in all probability give rise to many difficulties, as it is extremely difficult in many cases to say what is a cause of action for breach of an agreement, and what a cause of action in tort merely; the great majority of causes of action might be considered as either one or the other, according as the plaintiff chooses to frame his action. All actions for breach of duty arising out of a certain relation or employment, may be considered as actions in tort, or as actions for breach of contract, e.g. an action against a banker for not honouring a cheque; it is not clear whether such cases fail within this enactment or not. So, under the former law, A., as surety for a firm, joined with the members of the firm in making and delivering to the creditor a joint and several note on the faith that a co-surety should join in it, the creditor being party to the arrangement; and it was held, that by the arrangement the creditor had no right to negotiate the note without obtaining the signature of the co-surety; he did so, however, and an indorsee recovered against A. on the note, the creditor having become bankrupt and obtained his certificate; it was held, that A.'s debt was not proveable, and so not barred. It does not seem clear whether such a debt would or would not be proveable now, though it appears probable that it would. If the demand be not proved, however, as a plaintiff has his option in such cases to sue either in tort or in contract, it is apprehended that he might, notwithstanding the bankrupt's discharge, sue him afterwards; if he proved of course he could not do so, having by proof determined his election."
