Enoch Burke's former principal has told the High Court that she believed his behaviour at the school broke every part of the teacher's code of conduct.
Niamh McShane was giving evidence on the second day of Wilson's Hospital School's legal action against Mr Burke, who was dismissed for gross misconduct in January.
Enoch Burke claims he was fired because he refused to accept transgenderism at the school.
The school says he was let go because of his behaviour after his principal asked her staff to refer to a transitioning student by a new name in light of their wishes.
From the stand today, Niamh McShane described Enoch's behaviour at a staff meeting as "disrespectful."
When he later stood up at a religious service to call on her to withdraw what he described as her "demand" to staff, she said she felt embarrassed and "absolutely horrified" for the particular student.
After dinner later that evening, she said she felt she was being "hunted" by Enoch as he continued to plead with her.
At one point she said he was so close she could feel his "spittle," but she made it clear he had not spat at her.
Enoch Burke did not attend today but Ms McShane agreed to make herself available for cross-examination tomorrow should be wish to purge his contempt.
