"that employees holding the same position as the Applicant ("Mr Hickling") at the date of his dismissal were those commercial flying instructors ("pilots") who had joined the Respondents employment after the age of 60 rather than all pilots employed by the Respondents at the date of Mr Hickling's dismissal. In particular, the Tribunal erred in distinguishing those pilots who had joined the Respondents employment after the age of 60 from the remainder of the pilots by sole reference to the apparent absence of a contractual retirement age for the former, and without having due regard to the common nature of the terms and conditions and duties of the employment."
"Taking into account the previous history of Mr Hickling's employment in determining the class of employees who held the same position as Mr Hickling."
"(1) Subject to subsection (3), section 54 does not apply to the dismissal of an employee from any employment if the employee-
" "position", in relation to an employee, means the following matters taken as whole, that is to say, his status as an employee, the nature of his work and terms and conditions of employment;"
"The particular point we have here is this. There were senior supervisors who had joined Thames's service on or after1st January 1978 , and for them, if they can be regarded as a group on their own or looked at individually, their normal expectation of retirement was, at the time of the termination of Mr Barber's service, as it had been all along, 60. Mr Barber's was never 60. Subject to Mr Edelman's point that the letter should be disregarded because it did not change the contractual retirement age of anyone, for Mr Barber and all other senior supervisors who were taken into Thames's employment before1st January 1978 normal retirement age was, under the letter of26th October 1987 , from1st November 1988 to31st October 1989 , the age of 64. So the question is: is it permissible to treat all senior supervisors whose compulsory retirement age was 64 as a group separate from those senior supervisors whose retirement age was 60?
"In our view there has to be excluded from consideration in identifying the relevant group any term which only deals with retirement and is not linked to or a reflection of some other facet of the terms and conditions of the employer's employment."
"It was suggested that those words related only to the contractual terms and conditions... But that, I think, would be too limited. Terms and conditions of employment may include not only the contractual terms and conditions but those terms which are understood and applied by the parties in practice, or habitually, or by common consent, without ever being incorporated into the contract."
"In the case of persons whose contracts of employment lay down a retiring age, ... the retiring age may be regarded as part of that person's terms and conditions employment..."
"but the fact that within a group all do not have the same contractual retiring age does not mean that all do not remain members of the same group."
"Therefore, we have the situation that it is inconsistent with Hughes to rely on the circumstances by which it came about that those who entered Thames's employment before1st January 1978 had different terms and conditions of employment to those who entered the employment of Thames after that date, but it is relevant to have in mind the terms and conditions of employment, including terms and conditions as to retirement, which certain employees, including Mr Barber, had as the basis for their expectations as a result of the letter. I would therefore reject Mr Edelman's submission that we should disregard the letter.
"I agree, and only add a few words on the basis that I would allow the appeal even if Mr Edelman is right in his submission that in the definition of the word "position" contained in section 153(1) of the 1978 Act, the words "terms and conditions of employment" are to be confined to the contracted terms. It seems to me that in this context it is permissible to regard those who are subject to the contractual retirement age of 60 to be in one group, which I will call group A, and those who are not subject to the contractual retirement age of 60 as a second group, group B. Group A has and always has had a contractual retirement age of 60 and has had a normal retirement age of 60."
"It seems to me that Lord Allenbridge in the Highlands and Islands case may well have held that a term which was derived from the previous employment history was to be altogether disregarded, but I do not think that the Lord Justice Clerk or Lord Hunter held that view. The Lord Justice Clerk was, in my opinion, saying that a difference in terms and conditions as to retirement age does not necessarily and in all cases result in two groups or classes rather than one group or class. That I can readily accept. Otherwise it would be open to an employer to avoid the effect of the statute by imposing different terms and conditions as to retirement age and thereby creating new and smaller classes. That was, I think, the reasoning of the Employment Appeal Tribunal. But I do consider that a difference in terms and conditions as to retirement age is capable of being a factor which by itself distinguishes one group or class from another. The Industrial Tribunal found that it was a distinguishing factor in this case. I would not disturb the Tribunal's decision. Furthermore, I think that it was right."
"The Tribunal was referred to a schedule of flying instructors set out at pages 36 and 37 of the bundle which sets out the names of a number of instructors who started employment with the respondents when they were over the age of 60 [three names are mentioned there as well as Mr Hickling]. There was no evidence as to the conditions of employment which apply to them."
"Looking at the matter overall however, the Tribunal find that in the case of employees such as Mr Hickling who joined the respondents when they were already over the age of 60, there is no normal retiring age. Their reasonable expectation as to their retirement age at the relevant time, that is the date of dismissal, would be only that the provisions set out in document 2 in the bundle would be followed."
