So much wrong to unpick with her article:
This amendment abolished women-only facilities in the city including toilets and changing rooms – and plunged the council into illegality. It meant that male-born transwomen could access female facilities.
Male-born transwomen (are there any other kind) have been accessing female facilities perfectly legally prior to the Equality Act. The EA just gave people with the protected characteristic of "gender reassignment" the right sue if they are denied access to female facilities (subject to narrow exceptions). The amendment goes slightly beyond the scope of the EA, but it does mean it has plunged the council into illegality. It just means they are being more inclusive than the EA required. I am still to see an actual legal argument that the council behaved illegally.
To be clear the facilities are and have been women-only - transwomen are women.
The council further breached the Act by failing to consult with women and by not conducting an Equality Impact Assessment to assess potential negative consequences on those affected by the change.
Other statements Ann has made suggest she thinks that Equality Impact Assessments were required due to the Public Sector Equality Duty. However, at the time of the amendment the Public Sector Equality Duty was not a legal requirement - the EA commenced in stages. Oops.
With luck Sarah Brown will stand for the resulting by election and win back the seat for the LibDems. It will be good to have someone on the council who actually understands equality law.
