“Where an authority given to an agent has, without his knowledge, been determined by the death or lunacy of the principal, and, subsequently, the agent has, in the belief that he was acting in pursuance thereof, made a contract or transacted some business, with another person, representing that, in so doing, he was acting on behalf of the principal, the agent is liable, as having impliedly warranted the existence of the authority which he assumed to exercise, to that other person, in respect of damage occasioned to him by reason of the non-existence of that authority.”
“Yonge v Toynbee is clear authority that the loss of capacity in itself terminates the contractual arrangements, and therefore it is necessary for the Claimants to show that the process that they entered into is one that would show the retainer was maintained. ”
“It is impossible not to be sympathetic to the position in which the Claimant’s Solicitors find themselves. The starting point is the contractual position relating to the capacity of the Claimant and the position that arises on her losing capacity. There seems to me to be no doubt that Yonge v Toynbee remains good law, and that the relationship between a Solicitor and their client under a CFA agreement or indeed a private funding agreement, is contractual, and that Yonge v Toynbee is good authority and that the loss of capacity terminates that contractual arrangement.”
“I find, therefore, that as from [the date the Claimant lost mental capacity] the Claimant was no longer able to give instructions, and the contract was at that point frustrated.”
“… there is no need to consider what the parties thought or how they or reasonable men in their shoes would have dealt with the new situation if they had foreseen it. The question is whether the contract which they did make is, on its true construction, wide enough to apply to the new situation: if it is not, then it is at an end.”
