I'm very glad they won and grateful to Lynne Pinches for standing up.
Reading the judgement, it was disappointing to see, re. encouraging women's participation (my bolding):
"266 As to the second aim, I accept that women have been historically underrepresented among pool players. The FargoRate data indicates that in America they still are, and that is likely to be the case in the UK as well. Encouraging greater female participation is a clearly legitimate aim. I do not accept, however, that (were it not for the need to achieve fairness) excluding trans women from female competitions would be a proportionate means of achieving it. The Defendants’ evidence was that the only complaints they received other than those about fair competition were objections to sharing toilets, and that is an issue which could arise whenever trans women are present, whether or not they are competing in the same event."
The judge makes clear that if there hadn't been physical differences in performance he(?) would have thought it reasonable for trans women to play in women's tournaments to increase female participation.
Women have the right to compete against and socialise in a competitive environment exclusively with other women.
