"Subsection (1) shall not apply to the dismissal of an employee if it is shown that the reason (or, if more than one, the principal reason) for the dismissal was [one of those specified in section 58(1)]
"...the dismissal of an employee by an employer shall be regarded for the purposes of this Part as having been unfair if the reason for it (or, if more than one, the principal reason) was that the employee (a)was, or proposed to become, a member of an independent trade union, or (b)had taken part, or proposed to take part, in the activities of an independent trade union at an appropriate time ..."
"Where the reason or principal reason for the dismissal of an employee was that he was redundant, but it is shown that the circumstances constituting the redundancy applied equally to one or more other employees in the same undertaking who held positions similar to that held by him and who have not been dismissed by the employer, and either (a)that the reason (or, if more than one, the principal reason) for which he was selected for dismissal was [one of those specified in section 58(1)] or (b).....
"..Both had been employed for a matter of months, far short of two years, and must therefore satisfy us that the principal reason for their dismissal was not redundancy but their actual or intended (or supposed or supposed intended) membership and participation in the activities of an independent trade union, namely the one mentioned. Mere selection for redundancy on such grounds would not give us jurisdiction, if redundancy were in fact the principal reason for dismissal. On the other hand, if we have jurisdiction in either case, the applicant must succeed."
"We conclude that the scale of the redundancy was inflated so as to take advantage of the concurrent need for financial saving (not by any means a sudden coincidence but one that had been building up over a period) to get rid of those thought, rightly or wrongly, to be chiefly concerned with union organisation on the site. In these circumstances it is, we think, illogical to ask whether, if the redundancy had been limited to the number actually required, Mr Lane and Mr Knowles would have been properly included. That would resurrect the "no difference" rule. The question is relevant but relates only to the assessment of loss."
"There is furthermore no presumption that if redundancy is one of the two reasons for dismissal it must be the principal one. We find that as a fact Mr Lane and Mr Knowles, and others who have not brought proceedings, were dismissed principally because of their known or suspected union stance. Both applicants had somewhat unsatisfactory attendance records and Mr Knowles had also come to the notice of the authorities for fighting, on site but outside working hours, but that was not in our view a significant part of the respondents' reason in either case. The extent to which the redundancy was inflated for this purpose can be gauged by the subsequent fresh starts, instead of cutting back on redundancy or re-engaging. It appears that nearly all those dismissed were union members; all may have been suspected. There is no reason to attempt to assign some of the group to a class of legitimate redundancies, which would be sheer mindreading; the whole organisation was tainted; but it is significant that none of those originally dismissed was reprieved or subsequently re-engaged, and we do not accept Mr Stringer's explanation that in drastically changing, within a week, a redundancy scheme design to save half a million pounds in a year, he "leaned heavily" on two foremen who had then been on the site a few months and weeks, and foremen for one month and one week, respectively."
"..the tribunal is satisfied on the totality of the evidence that both Mr Lane and Mr Knowles were dismissed precisely for the reason that they had become members of the GMB and proposed to take part in its activities. The "reason" is what the employer either knows or believes: Abernethy v Mott, Hay and Anderson[1974] ICR 323 , 330B, per Cairns LJ. We are not prepared to decide cases on the opinions of those who decided not to bring complaints themselves."
"..the tribunal is satisfied on the totality of the evidence that both Mr Lane and Mr Knowles were dismissed precisely for the reason that they had become members of the GMB and proposed to take part in its activities."
"..A reason for the dismissal of an employee is a set of facts known to the employer, or it may be of beliefs held by him, which cause him to dismiss the employee. If at the time of his dismissal the employer gives a reason for it, that is no doubt evidence, at any rate against him, as to the real reason, but it does not necessarily constitute the real reason. He may knowingly give a reason different from the the real reason out of kindness or because he might have difficulty in proving the facts that actually led him to dismiss; or he may describe his reasons wrongly through some mistake of language or of law."
"..Mr Knowles said that he was warned that Mr Stringer had him on a list of those who had attended, that he told Mr Horan that he had not and that Mr Horan offered to "sort it out", but that that was overtaken by events."
