WPUK paid for legal opinion on the EHRC view given to the Scottish Data collection working group. They've also applied for funding & supported the work done by Jane Clare Jones & Lisa Mackenzie on the Political Erasure of Sex. I've seen a comment or 2 on twitter about this. WPUK themselves have also tweeted their correspondence with the EHRC on this too.
If the meeting of all the orgs in this fight determines that there's no action, protest, boycott etc that's feasible then surely they'll be going for the judicial review option? WPUK have done some groundwork on that already by the work I've highlighted above. They've also been (unnecessarily) critical of other legal cases that they have given opinions on, particularly where they have criticised the legal choices made in cases that have successfully challenged other aspects in this debate.
What I don't want to hear is any mealy mouthed 'there's nothing we can do, but anyone who makes a stand is a bigot' rhetoric from the self appointed 'leaders'.
If there's nothing that those supposedly in charge think women collectively can do without damaging their [GC orgs] reputations, then the only answer is judicial review.
