"(b) .... the employee was selected for dismissal in contravention of a customary arrangement or agreed procedure relating to redundancy and there were no special reasons justifying a departure from that arrangement or procedure in the case of the employee ...."
" The industrial tribunal, upheld by the Employment Appeal Tribunal in a judgment delivered on4 February 1988 , while holding that there was a customary arrangement in a wide sense, went on to say that that customary arrangement was not one within section 59 (b) of the Act: it may have related to redundancy but these employees were not selected for dismissal in contravention of that customary arrangement. As an industrial tribunal put it:
"There is, therefore, evidence that the customary arrangement was not an exhaustive one, but a preliminary step on the question of selection."
"If the arrangement was as we find it to be, that is a sort of halfway house restricting the area of selection as a first stage ..."
"9. ... the procedure or arrangement must relate to selection for dismissal and not any other aspect of the employer's behaviour, such as calling for volunteers, identifying the pool from which selection will be made etc."
