This is all so relevant for Irish equality laws! Including any men in definitions of 'woman' [and vice versa] make equality legislation read in an incoherent way.
We can have a lot of criticisms of the UK justice system, but you have to hand it to them - they are capable of applying logic, scientific fact and common sense in judgments like this and the Forstater and Bailey cases, which doesn't seem to be the case here, or in places like Australia and Canada.
I am slightly envious - imagine an Irish equivalent of FWS taking the government to the High Court to get all our TWAW laws and regulations overturned - no I can't imagine it either
Lord Hodge says the predecessors to the Equality Act used definitions of biological sex, and gender reassignment was added as a separate protected characteristic.
He tells the court that, after “painstaking analysis”, including people with a Gender Recognition Certificate in the sex group would make the Equality Act read in an “incoherent way”.
