I have appreciated reading Ally's responses in the thread.
It took me a little while to find the sex-based exemption Ally quoted above, but I did find it in Schedule 3, Part 7.
Gender reassignment
28(1)A person does not contravene section 29, so far as relating to gender reassignment discrimination, only because of anything done in relation to a matter within sub-paragraph (2) if the conduct in question is a proportionate means of achieving a legitimate aim.
(2)The matters are—
(a)the provision of separate services for persons of each sex;
(b)the provision of separate services differently for persons of each sex;
(c)the provision of a service only to persons of one sex.
What puts in more in context is the heading directly above, "Gender Reassignment". One wonders why Women's Aid (apart from the 'funding blackmail') did not fight on the grounds of Schedule 3, Part 7 (28) (1) & (2)(b)(c) - as well as Schedule 3, Part 7 (30) (a) & (b)?
Services generally provided only for persons who share a protected characteristic
30 If a service is generally provided only for persons who share a protected characteristic, a person (A) who normally provides the service for persons who share that characteristic does not contravene section 29(1) or (2)—
(a)by insisting on providing the service in the way A normally provides it, or
(b)if A reasonably thinks it is impracticable to provide the service to persons who do not share that characteristic, by refusing to provide the service.
Canadian group Vancouver Rape Relief (VRR) eventually won against Nixon on the grounds of (paraphrasing) born and raised girls within the culture. The win was in the context of their Human Rights Code:
"December 7, 2005
The B.C. Court of Appeal held unanimously that Vancouver Rape Relief has the right to prefer to train women who have never been treated as anything but female.
The Chief Justice said: "The respondent Society was entitled to give preference to women who are not post-operative transexuals, because there is a rational connection between the preference and the respondent's work or purpose."
I would add as a footnote to that, that VRR have always and still do, take on trans as clients, but they drew a line about trans counseling females.
Sorry, I have drifted a little off topic, and maybe it should have been started as a new thread. Would you like me to move it Prachet?
