"We bear in mind in reaching our decision that the claimant has been found in this case, and it really cannot be dressed up, to have presented a case that she has put forward falsely, in other words she has not told the tribunal the truth. Without more, to conduct a case by not telling the truth is to conduct a case unreasonably, it is as simple as that..."
"...a lie on its own will not necessarily be sufficient to found an award of costs. It will always be necessary for the Tribunal to examine the context and to look at the nature, gravity and effect of the lie in determining the unreasonableness of the alleged conduct."
"39. I begin with some words of caution, first about the citation and value of authorities on costs questions and, secondly, about the dangers of adopting an over-analytical approach to the exercise of a broad discretion. 40. The actual words of Rule 40 are clear enough to be applied without the need to add layers of interpretation, which may themselves be open to differing interpretations. Unfortunately, the leading judgment in McPherson [McPherson v BNP Paribas (London Branch)] delivered by me has created some confusion in the ET, EAT and in this court. I say 'unfortunately' because it was never my intention to re-write the rule, or to add a gloss to it, either by disregarding questions of causation or by requiring the ET to dissect a case in detail and compartmentalise the relevant conduct under separate headings, such as 'nature' 'gravity' and 'effect.' Perhaps I should have said less and simply kept to the actual words of the rule. 41. The vital point in exercising the discretion to order costs is to look at the whole picture of what happened in the case and to ask whether there has been unreasonable conduct by the claimant in bringing and conducting the case and, in doing so, to identify the conduct, what was unreasonable about it and what effects it had. The main thrust of the passages cited…from my judgment in McPherson was to reject as erroneous the submission to the court that, in deciding whether to make a costs order, the ET had to determine whether or not there was a precise causal link between the unreasonable conduct in question and the specific costs being claimed. In rejecting that submission I had no intention of giving birth to erroneous notions, such as that causation was irrelevant or that the circumstances had to be separated into sections and each section to be analysed separately so as to lose sight of the totality of the relevant circumstances."
