"3. Treated my own case in such an excessively harsh manner as to give grounds for believing that I may have been victimised as a result of my trade union links and activities."
"11. After the conclusion of the Respondents' evidence I then presented an opening argument on behalf of Mrs Roberts. During the course of this I began to refer to the trade union issue and I was stopped by the Chairman. He indicated that he did not wish to hear from me regarding this, but that he wanted to hear about this from Mrs Roberts in her evidence. At this time there was no indication that the trade union question could not be raised at all. On the first day of hearing additional witnesses were called on behalf of Mrs Roberts, but the case was adjourned before Mrs Roberts actually gave evidence."
"12. At the resumed hearing Mrs Roberts started to give evidence, and when I started to ask about the trade union issue the Chairman stopped me. When he did this I referred to my opening submissions and the fact that I had been told that the Chairman only wanted to hear from my wife regarding this matter. The Chairman said that I had not raised the matter with the Respondents' witnesses and therefore I could not raise it now, and that is my ruling."
"The appeal seems to turn on the issue of the appellant's allegation that her dismissal infringed s.152 of the 1992 Act. Her case was not pleaded as such and it was significant that this allegation was not , as I recall:
"When the question of Mrs Roberts' Trade Union connection was mentioned, I pointed out that nothing had been put to any of the respondent's witnesses under cross-examination, that the issue had not been raised - on the evidence which was not challenged - at disciplinary stage and that I would not permit him, as things stood, to open evidence which substantially changed the nature of the applicant's case. I am likely to have said - but I cannot with certainty say that I did - that if that issue was to be pursued, then we would have to recall the respondent's witnesses, with consequent delay and cost."
