The allegation spiralled to a series of alleged events over a number of years, including confrontations with staff, stolen paperwork, internet slander and formal complaints that involved the New Zealand Teachers Council, police, the Privacy Commission and Ombudsman, and the British Columbia Council of Teachers.
Mr Crichton said the "fundamental difference in evidence" from the two women was the crux of the issue.
Yesterday, principal Ross Scrymgour and ex-board of trustees chairman William Hamilton were interviewed under oath.
Mr Scrymgour was questioned by Dr Fox about the way he dealt with the conflict, and his appointment of board member Doug Abraham to investigate Mrs Fox's complaints.
"That was his role on the board, he had done a really good job with our HR stuff in the past," Mr Scrymgour said.
He had also been trying to be sensitive to a then pregnant Mrs Fox, he said.
Mr Hamilton defended actions taken by the board, that they acted on Mr Abraham's advice to seek independent mediation through the Department of Labour: "I think we jumped through hoops, we tried everything to get Emma to mediation. We were blocked on every path."
The hearing continues today.
