It is clear from the SC ruling that any exclusion of a trans person from single sex services has to be a proportionate means of achieving a legitimate aim.
Yes. This would relate to e.g. exclusion of a trans identifying woman from a women's rape crisis support group because she had changed her appearance to such an extent that this caused distress to other users because they believed her to be a man. However, she still has a right to provision.
Blanket bans - which the GC ideological captives interpret the law as being - simply do not meet that test.
This is where you seem to be very confused. A single sex service cannot include both men and women because then it is mixed sex. It's not a question of whether anyone can be banned, it's a question of the material reality of what the service is. The provider may then be unlawfully discriminating against people who require a single sex service.
Asking a trans person to use a third toilet would be discrimination
No, because per J. Swift:
the absence of a trans-inclusive lavatory is not the same as no lavatory at all. Even assuming interference with article 8 rights the interference would be less significant than considered by courts so far. However, even if that analysis is wrong, the Claimants’ case still fails. Even if there is a relevant prohibition on provision by a service provider or an employer of a trans-inclusive lavatory, and a consequent interference with article 8 rights, that interference would be capable of being justified taking into account the rights and freedoms of
others.
and in the case of asking someone with a GRC
GRC is irrelevant to single sex provision in the Equality Act. A piece of paper cannot change anyone's sex, as confirmed by the Supreme Court. Also, read the GRA. It's very clear that its impact is limited.
it is clearly illegal and against the recent HC ruling by judge Swift, were contrary to the EHRC CoP he ruled that alowing a trans woman to use the facilities that matches her gender would not be indirect discrimination against cis men.
You really do need to read what he actually said which was that the 'circumstances of the case would be decisive'. In practice it would of course be impossible to prevent any man from using the facilities because gender is a subjective concept, so the question would be whether lack of single sex provision discriminates against women.
a trans person does not break any laws by using facilities that matches their gender.
Not sure why anyone would provide gender based facilities, but it is true that it is not a criminal offence to use an opposite sex toilet. The law might be broken if somebody refused to leave an opposite sex toilet, or if a service provider did not make adequate single sex provision.
a bigot that harasses anyone in a in a single sex facility will quickly find themselves facing a judge for that harassment.
Saying 'I'm sorry, this is the ladies' has never been harassment. It's just the normal way of helping people to use the correct facility.
the CoP is facing a least 2 legal challenges..
Yes Jolyon Maugham is indeed raising funds on this basis. Many would question the ethics of this.
trans people are obviously going to use the facilities that match their gender presentation because it is too dangerous to do otherwise.
So you are just suggesting mixed sex services that anyone can use, but without the safety features of unisex provision. It's very unclear how this is less dangerous for anyone.
