"4. The facts of this matter are that the claimant was moved from Cambridge to Vranch House in Exeter sometime in early 2000. The respondents have several establishments throughout the United Kingdom, one being at Vranch House where the micro-technology service was situated. Those premises are owned by the Devon and Exeter Spastics Society. That Society made premises available to Scope under an informal arrangement. By the time the claimant's employment terminated she was the Manager of the service based at Vranch House. The staff there consisted of herself, an administrator and 2 engineers, Tom Warren and John Jones. The claimant is, as we have indicated, a highly qualified engineer. The micro-technology service provides aids to disabled persons, principally those suffering from cerebral palsy. The claimant's function was to carry out assessments of clients' needs. For this purpose she travelled throughout the United Kingdom. Her Personal Assistant made appointments for her to visit clients in various parts of the country. She would then assess what aids the individuals might need according to their circumstances and the nature of their disability. Dr Thornett's function would then be either to manufacture whatever equipment was needed or adapt existing equipment to meet the needs of the individual. In this she was assisted by Mr Warren and Mr Jones who were based exclusively at Vranch House. They did not travel. There was quite clearly a requirement for considerable liaison between Dr Thornett and those two individuals in order that she should, make clear precisely what was needed for particular clients. One feature of this case is that there has been no word of criticism whatsoever of Dr Thornett's professional skills, professionalism or dedication to the work, rather the reverse; there appears to have been some criticism of her due to the fact that she did not take as much holiday as she was entitled to and worked very long hours indeed in order to provide a service to the clients which the respondents, we are sure, regarded as first class. 5. The claimant lived at Crediton some 9 or 10 miles away from Exeter. The pattern of her working week was that she would usually go to the micro technology unit on Mondays before spending 3 or 4 days a week out in the field carrying out assessments. On her return, she would participate in the manufacture and adaptation of equipment and also bring back the work to be done by the 2 engineers. Another important feature of her duties was that she would make sure she kept up to date with the latest technological advances in this very specialist and important field. She was also the Manager of the Unit having budgetary responsibilities as well"
'… It seems to us that 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 cannot sensibly reconstruct the world as it might have been… 59. We respectfully agree with the formulation contained in the highlighted passage from that citation. However, we share Peter Gibson LJ's view, expressed in the extract from his judgment in O'
