“I can see no distinction in principle between the case where the agent never had authority and the case where the agent originally had authority, but that authority has ceased without his knowledge or means of knowledge. ... In my opinion he is then liable on an implied contract that he had authority, whether there was fraud or not. ”
“It is in my opinion essential to the proper conduct of legal business that a solicitor should be held to warrant the authority which he claims of representing the client; if it were not so, no one would be safe in assuming that his opponent's solicitor was duly authorized in what he said or did, and it would be impossible to conduct legal business upon the footing now existing; and, whatever the legal liability may be, the Court, in exercising the authority which it possesses over its own officers, ought to proceed upon the footing that a solicitor assuming to act, in an action, for one of the parties to the action warrants his authority. ”
“I see nothing in these authorities to contradict the contention of Mr. Mansfield, for the solicitors, that a solicitor who lends his name to the commencement of proceedings is saying (1) that he has a client, (2) that the client bears the name of the party to the proceedings and (3) that client has authorised the proceedings. He does not represent that the client has a good cause of action”
"In considering these submissions it is important to bear in mind that generally a solicitor conducting proceedings does not warrant what he says or does on behalf of his client. Thus he does not warrant that his client, the named party to the proceedings, has title to sue, is solvent, has a good cause of action or defence or has any other attribute asserted on his behalf ... There is an obvious distinction between such matters and the solicitor's own authority to act because the solicitor will usually know whether he has such authority or not. The imposition of strict liability on a solicitor for breach of warranty of authority is justified because otherwise the opposing party will be left without remedy against his supposed client. ” … "
“the faith of [the solicitors’] representation that they had authority to act for the defendant. ”
"a solicitor who acts in litigation without authority to act on behalf of the supposed client is responsible for the costs thereby incurred by the other party."
“The point can be illustrated, as it seems to me, by considering what the position would have been if Excel or its solicitors had asked BM Solicitors to give some form of express warranty or undertaking. If they had been asked whether they warranted that they had authority to act on behalf of their client in connection with the loan agreement and the execution of the charge, it seems to me to be highly likely that they would have agreed, though they might have asked why it was necessary, given the usual implication of a warranty of authority. But if they had been asked to warrant the identify of the client and to guarantee that he was the same person as the registered proprietor of 17 Richards Place, I think it is almost inconceivable that they would have agreed to do so. The likely response would simply have been that Excel must rely upon their own enquiries. ”
“... it seems to me to be virtually inconceivable that a solicitor would seek to exclude any liability for breach of warranty of authority; ... ”
“A solicitor does not warrant his authority where that issue is known to be controversial and the parties are engaged in litigation to find the answer.”
