"66. There is no stage in the investigation, disciplinary or appeal process at which the respondent makes any enquiry or investigation into the possibility that the claimant's concern, raised for the first time by Mr Abbott during the investigation and then raised by the claimant at his disciplinary hearing, that it was possible that the saliva test may have been contaminated in some way from cocaine on his hands from the bank notes handled by him. This failure by the respondent is unreasonable and wholly unexplained, particularly given that the possibility of this being an explanation for the positive test result was raised in the first instance by the respondent itself (Mr Abbott – investigating officer) in conversation with the claimant's solicitor. It was accepted by Mr Edwards (dismissing officer) and Ms Macleod (2 nd stage appeal) that if there was something to call the positive saliva test into doubt or an innocent explanation for the positive result then this would be highly relevant to the decision of whether that employee should be dismissed. 67. Given that Mr Abbott knew that the claimant had just eaten something before he gave his saliva test and given that the respondent understood the possibility of bank notes being contaminated by cocaine an investigation might have revealed factors which were relevant to the question of whether it was reasonable to conclude that this was gross misconduct and/or that the claimant be dismissed. 68. The charge was a very serious one, the claimant was a very long standing and loyal unproblematic employee and it is evident from the enquiries that were made by the respondent to Concateno (Mr Morris at 1 st stage appeal) and Keyclear (Ms Macleod at 2 nd stage appeal) that there was no problem in seeking advice on whether this was a viable possibility from those that advised them on such matters. Yet no enquiries or investigations were carried out at any point by the respondent to inform itself in that regard. 69. The respondent seemed in an unseemly rush to process the charge through to a decision to dismiss without taking the steps that any other reasonable employer would have done so. The fact of a positive drugs test result for cocaine seemed to close their minds to the normal principles underlying the investigating and processing of a charge of misconduct. 70. Although Ms MacLeod remedied the failure to have waited for the hair test result and to have understood its significance, her final appeal continued to do nothing to address the failure to have investigated the possibility or viability of contamination from bank notes providing and innocent explanation for the positive drugs test."
"72. The respondent submits that even if there are investigatory failings by them they would in any event have been fairly in a position to dismiss the claimant had they performed investigation into the possibility of contamination from bank notes at the time. The claimant argues the opposite."
"80. The respondent's report confirms that contamination would not be possible by way of the sample collection as long as the manufacturer collection guidelines were used. It does not in terms state that contamination could not have occurred from cocaine traces on the claimant's hands in some other way. It confirms that the bank notes are contaminated by cocaine. Neither does it address the fact that Mr Abbott and Mr Edwards were told that the cocaine test result showed that the cocaine had been ingested – this meaning that the saliva test showed that it had got into his system orally. It is understood to be accepting that the claimant's hands may have been contaminated by cocaine. 81. It confirms that the claimant will not have eaten or drunk anything prior to testing and that therefore anything that on his food would have cleared from his mouth. However the respondent did not assist in understanding what proper inference could be drawn from this. It is not easy to conclude that the correct inference is that this should mean that the cocaine could not have been ingested through the sandwich. This is because the respondent's own drug policy confirms that its saliva drug test will detect drugs within 10 minutes of consumption, the saliva test being intended to detect recent drug use. This is understandable and consistent with the safety objective of the policy. If the cocaine had been ingested through contamination on the sandwich from the claimant's hands that cocaine would have been ingested just over 10 minutes prior to the test and would therefore have been detected by the saliva test. Further, it was confirmed to Mr Abbott that the presence of benzoylecgonine confirmed the cocaine had been ingested. 82. The claimant's report on the one hand is not inferential and is instead equivocal – it expresses the claimant's clear professional view that the case is simply one of sample contamination. 83. From these reports I conclude that it would be improper and perverse of me to conclude that there is some sort of % chance that the respondent would in any event have dismissed the claimant if this issue had been investigated at the time. Such a conclusion would not be supported by these reports and would therefore by perverse. If one considers both reports side by side this shows one expert saying in clear terms – there is a high probability that the sample was contaminated and cannot be relied upon. The other expert confirms that there could have been cocaine on the claimant's hands, contamination could have been caused by the handling of the saliva sample if it was done properly but seems less clear in his/her basis for inferring that the eating of the sandwich could not provide a source for contamination. The respondent did not investigate the circumstances of the claimant's saliva test to ensure that it was done properly." 84. Accordingly I conclude that the claimant has been unfairly dismissed and that there is no Polkey reduction made to the compensation to which he is now entitled."
"The following principles emerge from these cases: (1) In assessing compensation the task of the Tribunal is to assess the loss flowing from the dismissal, using its common sense, experience and sense of justice. In the normal case that requires it to assess for how long the employee would have been employed but for the dismissal. (2) If the employer seeks to contend that the employee would or might have ceased to be employed in any event had fair procedures been followed, or alternatively would not have continued in employment indefinitely, it is for him to adduce any relevant evidence on which he wishes to rely. However, the Tribunal must have regard to all the evidence when making that assessment, including any evidence from the employee himself. (He might, for example, have given evidence that he had intended to retire in the near future). (3) However, there will be circumstances where the nature of the evidence which the employer wishes to adduce, or on which he seeks to rely, is so unreliable that the tribunal may take the view that the whole exercise of seeking to reconstruct what might have been is so riddled with uncertainty that no sensible prediction based on that evidence can properly be made. (4) Whether that is the position is a matter of impression and judgment for the Tribunal. But in reaching that decision the Tribunal must direct itself properly. It must recognise that it should have regard to any material and reliable evidence which might assist it in fixing just compensation, even if there are limits to the extent to which it can confidently predict what might have been; and it must appreciate that a degree of uncertainty is an inevitable feature of the exercise. The mere fact that an element of speculation is involved is not a reason for refusing to have regard to the evidence. . .."
"24. A ' Polkey deduction' has these particular features. First, the assessment of it is predictive: could the employer fairly have dismissed and, if so, what were the chances that the employer would have done so? The chances may be at the extreme (certainty that it would have dismissed, or certainty it would not) though more usually will fall somewhere on a spectrum between these two extremes. This is to recognise the uncertainties. A Tribunal is not called upon to decide the question on balance. It is not answering the question what it would have done if it were the employer: it is assessing the chances of what another person (the actual employer) would have done. Although Ms Darwin at one point in her submissions submitted the question was what a hypothetical fair employer would have done, she accepted on reflection this was not the test: the Tribunal has to consider not a hypothetical fair employer, but has to assess the actions of the employer who is before the Tribunal, on the assumption that the employer would this time have acted fairly though it did not do so beforehand."
"In my opinion the presence of cocaine and metabolite in the oral fluid sample from Alan Bailes cannot be due to handling bank notes alone. There are slight traces of cocaine on these notes but to suggest that this would produce a positive result above nationally agreed guidelines for legally defensible testing would be in error."
