"... there is no need for any contract of employment to specify a normal retirement age ... age of retirement is normally a matter of policy adopted by the employer, not of contractual arrangement between the employer and employee."
"... It is open to an employer to change his policy for the normal retiring age, and so long as it does not breach the contractual retiring age such a policy can change overnight. It requires, of course, properly to be communicated to the employees affected before it can take effect, but once communicated, I see no reason why the effect should not be immediate. ..."
"1. 'Normal retiring age' is the age at which employees in the relevant group reasonably expect or understand they are expected to retire. 2. If there is an express or implied term in the contract of employment specifying a retiring age, that will prima facie be the normal retiring age .... 3. Normal retiring age may feature as an aspect of an employer's employment policy. If it does, evidence relevant to normal retiring age may be found in the general policy of the employer. That may change from time to time. So long as there is no breach of a contractual retiring age, the policy may change with immediate effect, as communicated by him to the group of employees affected by the policy change."
"The Secretary of State was entitled to rely on a policy, even though the subject-matter of the policy was not incorporated as a term in the contract of employment. The policy was not itself a breach of any existing contractual term."
" 'position', in relation to an employee, means the following matters taken as a whole - (a) his status as an employee, (b) the nature of his work, and (c) his terms and conditions of employment."
"17. This Tribunal does not believe that the introduction of the pension scheme was sufficient to establish a normal retiring age for employees of the respondents [now the Appellants. But if the Tribunal is wrong on this point, we find that it would be effective only as regards the employees who in fact joined the scheme. Mrs Windows had not joined the scheme and until 1994 had had no right to do so. This meant that Mrs Windows was not in the same 'position' as those employees who had joined the pension scheme."
