“The manner in which business is ordinarily conducted requires that each party should be able to rely upon the solicitor of the other party having obtained a proper authority before assuming to act. It is always open to a solicitor to communicate as best he can with his own client, and obtain from time to time such authority and instructions as may be necessary. But the solicitor on the other side does not communicate with his opponent’s client, and, speaking generally, it is not proper for him to do so ... 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 authorised 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 should finally make clear two things. First, because even in the want of authority case the court is exercising its inherent jurisdiction, it must be right to say that the court ultimately has a discretion. But, second, it is of such importance that solicitors do not commence proceedings without authority leaving the opposing party without even a person or entity against whom an order for costs can be obtained, that it is difficult to contemplate circumstances where, if the lack of authority leads to that result, the discretion would be exercised in favour of the solicitors. The warranty by analogy, however, is not a warranty of solvency or that the costs will be recovered; it is that the plaintiff exists and has authorised the proceedings and no more.”
“It might, for example, sometimes in less than clear cut cases be right to leave the aggrieved party to his remedy in an action in damages for breach of warranty of authority against the solicitor. Having made clear that there is no inflexible rule, it is nevertheless right in my view to emphasise that a solicitor who clearly acted without authority, causing by his representation of authority the opposing party to incur wasted costs, must usually expect to be ordered to pay the costs in the exercise of the court's summary jurisdiction.”
“The result of the authorities and the demands of the twin objectives of making solicitors accountable for their unauthorised conduct of litigation and yet of protecting them against untested allegations of want of authority is that, whereas in clear cases of breach of warranty of authority and consequent recoverable loss, the court can summarily determine the solicitors’ liability for damages, in cases where there are real issues as to the facts or law, the courts should not do so but should leave the opposite party to start proceedings by issuing a claim for breach of warranty of authority.”
"Persons contracting with a company and dealing in good faith may assume that acts within its constitution and powers have been properly and duly performed and are not bound to inquire whether acts of internal management have been regular."
“There is, as it appears to me, a vital distinction between (a) an appointment in which there is a defect or, in other words, a defective appointment, and (b) no appointment at all. In the first case it is implied that some act is done which purports to be an appointment but is by reason of some defect inadequate for the purpose; in the second case there is not a defect, there is no act at all. The section does not say that the acts of a person acting as director shall be valid notwithstanding that it is afterwards discovered that he was not appointed a director. Even if it did, it might well be contended that at least a purported appointment was postulated. But it does not do so, and it would, I think, be doing violence to plain language to construe the section as covering a case in which there has been no genuine attempt to appoint at all. These observations apply equally where the term of office of a director has expired, but he nevertheless continues to act as a director, and where the office has been from the outset usurped without the colour of authority.”
“(1) The acts of a person acting as a director are valid notwithstanding that it is afterwards discovered— (a) that there was a defect in his appointment; (b) that he was disqualified from holding office; (c) that he had ceased to hold office; (d) that he was not entitled to vote on the matter in question.” (a) that there was a defect in his appointment; (b) that he was disqualified from holding office; (c) that he had ceased to hold office; (d) that he was not entitled to vote on the matter in question.”
