That was a really clear presentation that should put the rocket up any women's charities which are dragging their heels.
She strongly advises not waiting for the new statutory code and says charities have an obligation to follow the law now.
She describes EHRC's interim update as 'not law, but persuasive'
She signposts to Ben Cooper's paper as a good exploration of why the various loopholes which have been suggested will not work.
She explains why correct use of a SSE can never be direct or indirect gender reassignment discrimination.
She says single sex 'trans inclusive' services are unlawful but that an organisation can provide a mix of single sex, mixed sex and more specialised services as long as they are kept separate.
She says a single sex 'trans inclusive' service would risk a claim of direct discrimination against men and failure to provide a single sex service could risk a claim of indirect discrimination against women.
She advises charities to revisit their charitable aims, be very clear about who their beneficiaries are, review their policies to ensure they are compliant with FWS and to record their decision making processes.
She advises against charities relying on untested areas of law like positive action, or seeking advice from activist orgs like the good law project. She strongly emphasises trustees' obligation to follow the law and not invalidate their insurance. She warns against becoming a test case and tying up all the charity's resources in legal battles for several years.
The FAQ that @Justme56 linked to, which wasn't written by Audrey Ludwig, is a terrible fudge and seems to suggest that it's still lawful to run 'trans inclusive' 'women's' services as long as you don't call them single sex. It says 'Inclusion is legal provided your policies are clear and consistently applied' which is not what AL said at all. It also plugs the good law project as looking for cases to take to ECtHR using positive action.
Quite obviously whoever wrote it doesn't like the ruling and is still looking for loopholes.
