I'm going to read the thread with interest!
But I assume you would think their requirement for a trans person alone would be illegal positive discrimination. Since, contrary to the wording of the ad, there is nothing in Schedule 9 to excuse this particular requirement, which must therefore always be illegal, no matter what.
Yes, I think that would be consistent with the words in the Act. I'm open to being shown to be wrong either by something in the Act itself or a judicial decision setting out a different way the act should be read. GIven that most non-GR people are unlikely so much to want to work in a post where the organization feels it needs a GR person as to take legal action, the fact that this point hasn't been adjudicated isn't much of a surprise.
Two comments from the thread I do agree with - firstly @crossant: They could equally well say they were invoking section 123 of the Road Traffic Act 1988. It's ignorant, silly, and shows a misunderstanding of the law, but none of those things are illegal.
And secondly @IrnBruAndDietCoke: Regardless of whether it’s correct in law, you’d have to be a real cunt to apply for that job if you didn’t have the preferred characteristics.
Have a read of the explanatory note to Schedule 9:
787.This paragraph provides a general exception to what would otherwise be unlawful direct discrimination in relation to work. The exception applies where being of a particular sex, race, disability, religion or belief, sexual orientation or age – or not being a transsexual person, married or a civil partner – is a requirement for the work...
I suppose you're saying that there's no need to mention that being (vice not being) a transsexual person doesn't need to be mentioned there, because that kind of discrimination is in fact not "otherwise" unlawful? If the organization advertising the job ad had seen it that way, they would have had no need to mention Schedule 9 at all.
