"However, it appears that the patient, for whatever reason, did not receive his medication at a time when the applicant signed his record indicating that he had so received it."
"... the employer will normally not act reasonably unless he investigates the complaint of misconduct fully and fairly and hears whatever the employee wishes to say in his defence or in explanation or mitigation. ... If an employer has failed to take the appropriate procedural steps in any particular case, the one question the industrial tribunal is not permitted to ask in applying the test of reasonableness posed by section 57(3) is the hypothetical question whether it would have made any difference to the outcome if the appropriate procedural steps had been taken. On the true construction of section 57(3) this question is simply irrelevant. It is quite a different matter if the Tribunal is able to conclude that the employer himself, at the time of dismissal, acted reasonably in taking the view that, in the exceptional circumstances of the particular case, the procedural steps normally appropriate would have been futile, could not have altered the decision to dismiss and therefore could be dispensed with. In such a case the test of reasonableness under section 57(3) may be satisfied. . .. If it is held that taking the appropriate steps which the employer failed to take before dismissing the employee would not have affected the outcome, this will often lead to the result that the employee, though unfairly dismissed, will recover no compensation or, in the case of redundancy, no compensation in excess of his redundancy payment. Later on, Lord Bridge cites with approval a passage from Mr Justice Browne-Wilkinson, as he then was, in the case of Sillifant v Powell Duffryn Timber Ltd[1983] IRLR 91 , where the Judge said this: "
"They are [industrial tribunals], in our view, only required to consider [ Polkey ] that, if it appears to them that the point arises as a possible credible point. Then of course they must investigate it, as they must investigate any matter which appears to them to tell on the likely size of their award. ... A Tribunal is not obliged to consider hypothetical matters unless they seem to be real possibilities or probabilities."
"19 ... In broad terms, it appears to us that there will be situations where one can say that what went wrong was 'merely' procedural. Equally, in broad terms, we think there will be situations where one can say that an employee has been deprived of 'something of substantive importance' .... We see no need to discard entirely terminology of this kind; and while in many cases it may be inappropriate to allocate the particular facts to either category, or to do so without enquiry, it seems to us that a distinction between the 'merely' procedural, and the more genuinely 'substantive' will often be of some practical use, in considering whether it is realistic, or practicable, or indeed 'just and equitable' to embark upon an attempt to construct a hypothesis, enabling one to assess what would have happened, if only it had. 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. .... . 20 So far as Lord Bridge's observations in Polkey are concerned, it is no doubt correct to say that he is not drawing categorical distinction between 'procedural' cases and 'substantive' case, or excluding the latter as a category from the possibility of what has become known as a Polkey deduction. If in a particular case it is possible to say ... that the fact of the matter is that applicant has lost only a one-in-five chance of being retained, then we concur with Peter Gibson LJ in saying that there is no arguable case that he should have been compensated on the same footing as if he was bound to have been retained. It does not seem to us that Lord Bridge was considering or commenting upon the question of how or when one would discover what would have happened, but for the employers' unfair acts or omissions; and we cannot read him as trying to lay down a general proposition, to the effect that an employer will always be entitled, however fundamental his unfair course of action may have been, and however speculative the question of what would have happened but for these acts and omissions, to insist upon a tribunal hearing a tract of evidence, designed to reconstruct the world that never was, and ask for a finding as to the likelihood of the employee having been dismissed in that speculative world."
