Unfortunately, the GRA actually changes a person's sex, so if a transwomen gets a GRC, they become a member of the female sex. Quite an amazing scientific achievement really.
Yes but the Equal Status Act - updated in light of the GRA, and the GRA cannot "supersede" it because it's a different act on the statute book - is the equality legislation that forms the basis for discrimination cases.
Cosmetic services that involve physical contact are specifically allowed to discriminate on the grounds of gender. And since the ESA specifies that the grounds of gender has 3 categories (male, female, transgender person), then a cosmetic service like waxing can theoretically, legitimately restrict itself to just one of those 3 categories.
Theoretical so far, because no one has tested it yet. The existing barbers cases aren't a direct precedent for something like waxing because the nature of the physical contact is different in genital waxing and could draw on the "embarrassment in presence of other gender" clause in a way that cutting hair on the head would not.
And it wouldn't protect you from having to provide treatment to a transwomen with a GRC but without physical transition.
Not necessarily true. It might, because of the above exemption, but it will take a test case to establish.
I keep repeating that it needs a test case because I don't think it's helpful to catastrophise and give up before the battle has begun. A waxmyballs-type situation has the potential to be dismissed way in Irish law but it will take some unfortunate but very brave small business owner to fight it. It would be worth fighting, though, and I'd happily donate to a crowdfunder if a case came up.
Caveat: I'm not a lawyer, but the above is what I remember from a conversation with a friend who is. It would be good to hear the perspective of some other Irish legal bods on the issue.
