‘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.’ 32. In relation to the retainer in the present case, Mr Smith pointed to clause 2 of the CFA under the heading ‘Your responsibilities’, which provided that the claimant must ‘[g]ive us instructions that allow us to do our work properly’ and ‘[c]o-operate with us’
“So perhaps it would be simpler to say at the outset that frustration occurs whenever the law recognises that without default of either party a contractual obligation has become incapable of being performed because the circumstances in which performance is called for would render it a thing radically different from that which was undertaken by the contract. Non haec in foedera veni. It was not this that I promised to do.”
“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.”
“1. The doctrine of frustration was evolved to mitigate the rigour of the common law's insistence on literal performance of absolute promises …. The object of the doctrine was to give effect to the demands of justice, to achieve a just and reasonable result, to do what is reasonable and fair, as an expedient to escape from injustice where such would result from enforcement of a contract in its literal terms after a significant change in circumstances …. 2. Since the effect of frustration is to kill the contract and discharge the parties from further liability under it, the doctrine is not to be lightly invoked, must be kept within very narrow limits and ought not to be extended …. 3. Frustration brings the contract to an end forthwith, without more and automatically …. 4. The essence of frustration is that it should not be due to the act or election of the party seeking to rely on it …. A frustrating event must be some outside event or extraneous change of situation …. 5. A frustrating event must take place without blame or fault on the side of the party seeking to rely on it ….”
“37. Applying the established test and the above principles it is clear, in my judgment, that termination of a solicitor’s authority by reason of mental incapacity does not, in itself and in the usual case, frustrate the underlying contract of retainer. It is even clearer, in my view, that a retainer such as the CFA in this case, entered into with a person known to have fluctuating capacity, is not frustrated by the loss of such capacity. 38. First, whilst the giving of instructions and the consequent authority of a solicitor to act on behalf of a client according to those instructions is certainly central to the contract in question, the manner and capacity in which those instructions is given is not. The supervening inability of a party to give instructions personally, with the likelihood (if not the certainty) that a deputy will be appointed, does not change the nature of the contract of retainer, radically or even significantly. The position would seem no different to a company providing instructions to its solicitors through its board of directors. If the entire board resigned, there might be no individual capable of giving instructions until a new director was appointed, but that would not in itself change the nature of the contract of retainer so as to frustrate it. 39. Second, the obligation to provide such instructions is express in the CFA and would in any event be implied, from which it follows that an inability to provide such instructions cannot be said to be a matter not dealt with by the contract. The supervening incapacity of a client may cause a delay in performance of the obligation, but such a delay and its consequences (including whether the contract was repudiated) would be a matter for the application and enforcement of the terms of the contract. 40. Third, even if any delay caused by supervening incapacity was not within the scope of the contractual terms, it is clear that mere delay does not frustrate a contract. It would only amount to a frustrating event if the delay is ‘abnormal, in its cause, its effect or its expected duration, so that it falls outside what the parties could reasonably contemplate at the time of contracting’: see Chitty on Contracts31st ed. para 23-035. Given that a claimant may regain capacity or otherwise have a deputy in place in short order, the delay arising from supervening incapacity would not seem to be of sufficient expected duration to regard the retainer as having been frustrated. 41. Fourth, in cases such as the present, the possibility that the client will at some point lose mental capacity is plainly a matter which was within the reasonable contemplation of the parties. The fact that the CFA here contained an express provision that the retainer would terminate on the death of the claimant, far from supporting the case that supervening incapacity was a frustrating event, indicates that the parties did not regard incapacity of the claimant as something which should bring the contract to an end. They could equally have provided that the retainer would terminate on incapacity, but did not do so. 42. Fifth, far from being unjust to hold the parties to their literal bargain, it would plainly give rise to an unjust and unreasonable result to treat a retainer as terminated by reason of what may be a fleeting period of incapacity. To do so would be contrary to the principle that the doctrine of frustration should be confined within narrow limits and cannot be lightly invoked: it would result in the frequent termination of retainers (on the basis of arguments advanced by a non-party to the contract, such as the defendant) where neither party wished that to be the outcome and neither saw any difficulty in continuing to perform their obligations. 43. Sixth, it is established that supervening incapacity of an employee does not necessarily frustrate a contract of employment, despite the personal nature of that contract: see Chitty on Contracts31st ed. para 23-038. In deciding whether the employment is frustrated by such incapacity, the court will consider the nature and likely duration of the incapacity, the prospects of recovery and whether performance of the contractual duties would be either impossible or radically different. A client’s role in a contract of retainer is far less personal than a contract of employment and can readily be assumed by a deputy, further indicating that incapacity does not in itself frustrate such a contract. 44. I acknowledge that the decision of the Senior Costs Judge in Findley v BarringtonJones (above) is highly persuasive authority in the opposite direction. However, that decision was based on what I consider to be a misreading of Yonge v Toynbee. Further, the Senior Costs Judge did not consider the principles governing the frustration of contracts as set out above, nor their application to the effect of supervening incapacity on a solicitor’s retainer.”
“As for the objection that the solicitors are not qualified to appear for the lunatic, there is no doubt that they were authorized to act when she was first taken ill, and I think that the retainer would extend to enable them to take such steps as became necessary in consequence of her lunacy.”
“The application of the above principles [concerning physical and legal incapacity] at first sight gives rise to some conceptual difficulty in relation to the law of agency. Here it has been held that a power of attorney was ‘void’ on the ground that it had been executed by a person of ‘unsound mind’ who did not ‘know what he was doing’; and it has been said to be a ‘general rule of law that a lunatic cannot appoint an agent’. A similar rule has been applied in cases of the supervening insanity of the principal …. In all these statements it is the fact of the principal’s insanity (actual or supervening) which is regarded as decisive. They give rise to difficulty because they make no reference to the agent’s knowledge of the insanity; and it is this factor of knowledge which is normally decisive in determining the validity of contracts with mental patients. The statements are, however, all concerned with the agent’s authority rather than with the contract of agency: indeed, in the leading case on the effect of the principal’s supervening insanity there was no contract at all between principal and agent (who were husband and wife). The statements also all appear to be concerned with forms of ‘insanity’ so extreme as to give rise in fact to an incapacity to continue the relationship of principal and agent. Thus they can be explained on the ground that, in the present context, a factual (as opposed to a legal) incapacity suffices to bring a contract to an end ….”
“Mental incapacity. Mental incapacity in this context means inability to appreciate the nature and quality of the act done, but plainly there can be varying degrees of incapacity. In such circumstances, it is perhaps not surprising that the blunt rule assumed to apply to cases of death, viz. that actual authority automatically ceases, probably does not apply to cases of incapacity. As with the position in respect of mental incapacity in a principal existing at the date of appointment, the law is currently unsettled on the effect of an agent’s actual authority of supervening incapacity in the principal. It is submitted that the better view is that supervening mental incapacity does not terminate an agent’s actual authority until the agent becomes aware, or at least ought to have become aware, of the incapacity, unless the parties have expressly agreed that incapacity is to terminate the mandate. Recent authority has confirmed that where the agent has a contract of appointment, that contract at least is not automatically determined by supervening illegality [sic - i.e. supervening incapacity]. In the relatively few other relevant cases, the notion of automatic termination has generally been assumed by the parties rather than contested and decided, or it appears that the agent was aware of the incapacity ….”
