"98 General (1) In determining for the purposes of this Part whether the dismissal of an employee is fair or unfair, it is for the employer to show – (a) the reason (or, if more than one, the principal reason) for the dismissal, and (b) that it is either a reason falling willing subsection (2) or some other substantial reason of a kind such as to justify the dismissal of an employee holding the position which the employee held" , and, secondly, s.146(1) ( c) of TULRA, which provides: "146 Action short of dismissal on grounds related to union membership or activities (1) An employee has the right not to [be subjected to any detriment as an individual by any act, or any deliberate failure to act, by his employer if the act or failure takes place] for the sole or main purpose of - (c) compelling him to be or become a member of any trade union or of a particular trade union or or of one of a number of particular trade unions."
"30. In all the circumstances, and having regard to, the claimants' lengths of service and excellent work records, the clear injustice being caused to them; the fact that POM was aware of the injustice; the fact that POM was aware that Mr Molloy was the claimants' chosen Trade Union representative and that he had been advising them throughout; the fact that there was no obvious reason why Mr Molloy should not be allowed to accompany them; the difficulty which the claimants would have arranging for a work colleague to accompany them at the Appeal Hearing; and the fact that they would not be entitled to representation at the Appeal Hearing by a Union of which they were not members, not to mention the obligations on POM in terms of Section 10 of the 1999 Act, we arrived at the view that POM's refusal to allow Mr Molloy to accompany the claimants at the Appeal Hearing, and indeed at the meetings when the claimants were advised that they were to be dismissed, were not the actings of a reasonable employer and rendered their dismissals procedurally unfair."
" …we were mindful of the very competitive nature of the industry in which Petrofac operates and we did have some sympathy for PFM as regards its bargaining position when it came to contracting with Kerr McGee, no doubt a valued customer which is in a position to wield considerable influence over it." and at paragraph 34, they comment further : "
"If there has been a 'merely' procedural lapse or omission, it may be relatively straightforward to envisage what the course of events would have been if procedures had stayed on track, rather than briefly leaving the track in this way. If, on the other hand, what went wrong was more fundamental, or 'substantive', and seems to have gone to the ' heart of the matter', it may well be difficult to envisage what track one would be on, in the hypothetical situation of the unfairness not having occurred. It seems to us the matter will be one of impression and judgment, so that a tribunal will have to decide whether the unfair departure from what should have happened was of a kind which makes it possible to say, with more or less confidence, that the failure made no difference, or whether the failure was such that one simply cannot sensibly reconstruct the world as it might have been."
