The utmost that can be said against Messrs Williams & Neville in their character of solicitors is that they trusted overmuch to the plaintiff Hallet, whom I suppose they had good reason for trusting, and that they did not, under the circumstances, take the extreme care which ought to be taken in joining a co-plaintiff with him; in other words, there is nothing to be said against them professionally. It seems to me to be clear that they acted without authority in joining Geilinger as plaintiff, and the real question is whether they have thereby rendered themselves liable to the defendants for costs...
It being, therefore, established that this action was, so far as Geilinger is concerned, brought wholly without his authority, the way is cleared for the main question, which is whether the solicitors for Geilinger ought to pay the defendants' costs. I take it that there is no question that if Geilinger, having been made plaintiff, was in any way liable, he would have a remedy over against his solicitors who acted for him. That is recognised in all the cases. But the question is whether the defendants have a right as against the solicitors to make them pay, and that depends on what is called more than once in Fricker v Van Grutten "the principle" of the cases on the subject...
The result is that the principle now established is not that the plaintiff is necessarily to pay the costs, but that the solicitors who have improperly made him plaintiff are to be substituted for him. As was said by Rigby LJ in Fricker v Van Grutten the solicitor "having put forward Mr Weller as one of the persons to pay the costs ordered to be paid by the plaintiffs, he must be substituted for Mr Weller, and must pay the costs which Mr Weller has been ordered to pay to the defendants." So in this case Messrs. Williams & Neville, having put forward Geilinger as one of the persons who ought to pay the costs of the defendants, and having no authority to do that, must be substituted for him and made liable to indemnify the defendants. But can that be done only at the instance of the plaintiff, or can the defendants apply, as they have done in this case? It seems to me that when once the principle is arrived at, it is clear that the defendants are entitled to make the application. The plaintiff was formerly entitled to apply for relief by way of indemnity, because he was under liability to the defendant, but now that there is no such liability there is nothing for him to apply for. But to stop short of the whole substitution of the solicitors for the plaintiff, and to say that the defendants are not entitled to any remedy, but that it can only be given at the instance of the plaintiff, would be to depart from the principle - to adopt it in part instead of in whole. I think that these applicants are right, and that Messrs. Williams & Neville must now be ordered to pay to the defendants their costs of the action so far as they are attributable to the infant plaintiff Geilinger having been made a party, and also their costs of this application [emphasis added].
