"13 ... We take the view that, on the proper construction of that clause, [the relevant clause of his contract] the Respondents could require the Applicant to perform duties outside the function of Stores Operative, so that it expanded rather than restricted the range of duties which the Applicant could be required to undertake."
"This title does not define or limit your employment. The Company may require you from time to time to do any work within your capacity "
"15 ... We take the view that there is no evidence to support the existence of any variation to the Applicant's contract of employment. We consider that the proper view of the situation is that the Respondents, as a concession to the Applicant, allowed him to perform tasks within his job description which were also within his physical capability. In so doing, they acted as a good employer in obtaining medical advice and in finding work for the Applicant which he could do. However, we take the view that the Respondents did not, by that action, alter the scope of the Applicant's obligations to them."
"(2) For the purposes of this Act an employee who is dismissed shall be taken to be dismissed by reason of redundancy if the dismissal is attributable wholly or mainly to -
"(b) the fact that the requirements of that business for employees to carry out work of a particular kind ... have ceased or diminished or are expected to cease or diminish."
"As we understand that decision, the Court of Appeal applied what has been called the 'contract test'."
"... Further, it was an essential foundation of the decision in the first Nelson v British Broadcasting Corporation case that the court decided whether there was a cessation or diminution of the requirement under the contract of employment for employees to perform the particular kind of work that Mr Nelson was employed to do. That was necessary to the ratio desidendi of the decision and as the Appeal Tribunal held was binding upon them."
"In my judgment the facts found by the industrial tribunal afforded ample justification for the majority view that the dismissal was due to redundancy in the second plumbing post, that is, resulting from the introduction to the staff of a heating engineer to carry out work of one particular kind, which was distinct from general plumbing, and the subsequent reduction of the employers' requirement for plumbers to carry out work of another particular kind, namely, plumbing."
"In each case it must be for the industrial tribunal to decide whether the re-organisation and re-allocation of functions within the staff is such as to change the particular kind of work which a particular employee, or successive employees, is or are required to carry out, and whether such changes has had any, and if so what, effect on the employer's requirement for employees to carry out a particular kind of work."
"As to the question whether the employee was redundant, for my part I am quite satisfied that the modernisation of the heating arrangements diminished the requirement of the employers for plumbers, because the maintenance of the plant as modernised was not a plumber's work. The fact that the heating technician did some plumbing work, or would be required to do some plumbing work, does not alter the situation. Sir Denys Buckley has dealt with the matter fully; I agree with his judgment on that part of the case and I also with the reasoning and judgment of the appeal tribunal."
