They've just tweeted:
"BREAKING: We're pleased to announce that Fair Play For Women has instructed a barrister to evaluate the lawfulness of the ONS approach regarding the definition of sex in the Census."
"If the ONS has broken the law we will hold them to account in the high court by judicial review"
This is great news! I hope they do have a case.
Although, as an aside I'm fed up that so many brilliant women are having to spend so much time, money and effort using the courts to get people who really should know better to do the basics of their jobs properly! It appears to be the only way, though. And a very effective one at that... ideology and bullying tactics don't fare so well in a court of law.
