"frustration occurs when some reasonably unforeseeable event occurs which makes the contract impossible or unlawful to perform, or radically different from what the parties originally intended. When such a contract is frustrated, it comes to an end without a dismissal on the part of the employer, or a resignation on the part of the employee."
"It seems to us that an important question to be asked in cases such as the present – we are not suggesting that it is the only question – is: 'has the time arrived when the employer can no longer reasonably be expected to keep the absent employee's post open for him?' It will thus be seen that the sort of question which has to be considered when it is being decided whether a dismissal in such circumstances was unfair, and that which has to be considered when deciding whether the contract has been frustrated, are not dissimilar."
"I do not take the simplistic mathematical approach of simply counting the pointers in each direction. If one factor in favour of the Applicant had seemed to me to outweigh the others, then I would have had no hesitation in finding in favour of the Applicant. I am unable to identify any such factor amongst those that seemed to me to assist the Applicant. In all of the circumstances, and with considerable sympathy for the position in which the Applicant finds himself, I have concluded that this contract was indeed frustrated as is argued by the Respondent. Since it was frustrated, the Applicant was not an employee at the date upon which he claims to be entitled to a redundancy payment; his claim is not therefore well-founded and is dismissed."
"The Applicant argued that there was a considerable prospect of recovery in that he would have returned to the employment of the Company but for his belief that it was in its 'death throes' before the actual receivership. Mr Quinn argued that the subsequent failure of the Applicant to obtain any work and his present reliance upon walking with a stick, indicated that there was little prospect of recovery. I also bear in mind that the Applicant has failed to make any realistic applications for work. I accept Mr Quinn's submission that the Applicant had no real intention of going back to work and that there was no prospect of his doing so."
"He met with the company's managing director [a year after the injury or just thereafter] and told him that he had lost the use of his left hand and was, and would remain, permanently unfit for work as a joiner. Although, given his condition, there was no prospect of finding any alternative work for him, the employers agreed to keep him 'on the books' so he could draw the more generous pension benefits which would apply after he reached age 60 on31 March 1996 . Nothing was said as to what was to happen after that date. Mr McMillan subsequently made an application to an employment tribunal claiming a redundancy payment. His application was refused. Thereafter, the employers sent him a letter saying: "
"Nevertheless, save in cases of supervening illegality, is there anything to prevent parties ratifying, and continuing for a time, or to the end, to treat subsisting a contract which the court would have called frustrated? There seems to be no reason why they should not do so, though if the court is invoked it may still treat the contract as frustrated at the date of the frustrating event, whatever the opinions of the parties or their subsequent actings."
"It respectfully seems to us that if a contract is frustrated by operation of law, there is nothing to revive and a nullity has to be declared. There is nothing to prevent parties entering into a new arrangement, but they must do so with the clear intention to achieve that result or else there is no consensus ad idem. If the parties both think that what is in fact the case is that the previous contract is still subsisting, there is no intention to create a new contract since there exists a mistaken belief on the part of both parties that the old contract is subsisting. The proper legal analysis of that position is that the contract is frustrated, is dead, and nothing has taken its place."
