"Doing the best we can on the balance of probabilities we conclude that while Mrs Delaney did not have a general anti-Union attitude - we think that is unlikely - she perhaps did not particularly like COHSE and found COHSE's active and persistent local representative, the Applicant, difficult to deal with and uncongenial, and probably had some bias against him linked to his Trade Union role. It is not possible to say that in any of the pre-Marley incidents there was the degree of intention to penalise or deter the Applicant that section 23(1) requires, but his Trade Union role and activities would probably not have helped him in his professional and career relations with Mrs Delaney; and having seen and heard both of them we think that their respective personalities and styles would make for difficulties of communication and co-operation.
"8 We turn now to consider whether the Applicant has satisfied us as to his claim in respect of those matters which are within the time limit. So far as Mrs Delaney was the prime mover in the two acting up appointments of Mr Marley, which she probably was (though she discussed them with Mr Sims and Dr Green), we have borne in mind our conclusions set out above as to the pre-Marley matters and have, therefore, considered critically and carefully what she has said as to the reasons for the Marley appointments. We have, also, borne in mind the evidence of Mr Sims and Dr Green about those matters. The Applicant makes no allegations against them of bias against him because of his Trade Union activities. Their evidence was given before that of Mrs Delaney and she did not hear it. She only attended one the third day of the hearing. Her evidence on these matters was in line with theirs. In so far as the appointment of Mr Marley in July and September rather than the appointment of the Applicant to the acting up posts is to be regarded as action taken again the Applicant, the Respondents have satisfied us as to the purpose of those actions. They have satisfied section 25(1)(a).
