^"Joshua Sutcliffe said "well done girls" to a group that included a pupil who identified as a boy while teaching at a school in Oxford in 2017.
It can be reported for the first time that both parties settled out of court.
[...]
A reporting restriction made during the employment tribunal prevented identifying anyone involved in media reports and details of the settlement have not been made public.^*
I remember this story when it first came out. I Googled it recently as I was curious as to the outcome. It seems that the teacher "won" in the sense that he got an out-of-court settlement?
