The petition was to annul a longstanding marriage which produced children, the husband now having transitioned to transwoman, the claimed basis for annulment was that at the time of marriage the husband was a she.
This was rejected, the court ruling that his presentation at the time, fathering children, etc. shows that he was at the time a he, even if now a she.
Thus all this innate gender identity, female soul, assigned at birth, etc is rejected as bollocks.

She is now a she, but when talking about their historical self 'he' is the appropriate pronoun.
I.e. Bruce Jenner won Olympic gold medals. He was decathlon medalist.
