Is self id a matter for devolution?

[Lysistrataknowsherstuff]

Apologies if this question has been posted before, but I couldn't find it.

With Scotland having its own consultation - and it seems to be a bit further ahead with self id than the rest of the UK - I just wondered whether self id will be a matter for Westminster to decide for the UK as a whole, or for each country to decide in its devolved parliament/assembly?

If so, we might end up in a very strange place where up in Scotland self id is accepted but across the border a trans woman is still a man without a GRC. My head hurts just thinking about the practicalities.

Added to this, with Stormont still dissolved, would this just be one of the areas where it's put on hold until a government is formed there eventually?

I remember back under Blair he only got some controversial England & Wales specific legislation passed because he got the Scottish MPs to vote on it, despite it not affecting Scotland. Does this still happen? I remember the outcry but then it all seemed to die down.

No because of EVEL. Scottish Mps cannot vote on England only legislation.

And separate legal system already in Scotland.

Yes I'm aware of the separate legal systems - I'm unclear as to whether the decision to have self id will be made for the UK as a whole or whether it will be up to each country to decide independently.

Thanks for the clarification on EVEL.

afaik its fully devolved and for each part of the UK to decide themselves. Wales might be the exception so Westminster will vote for England and Wales.
