Let's take a moment to remind ourselves of how the 'Greatest Authority on the Equality Act in the World' introduced themselves to this thread:
Oh dear, another overexcited GC not reading the clarification properly. Incorrect that it’s ’not allowed’, this all depends whether the WI is offering a single-sex service under Schedule 3 and whether its membership policy serves a legitimate and proportionate aim.
A quick dose of abuse followed by an erroneous reference to the wrong part of the Act. When their error was pointed out, they swivelled to the correct part of the Act but without apparently reading it as they assumed that it was the same as Schedule 3 but for organisations.
When this error was pointed out, they then read the relevant part of the Act and, realising that it really doesn't support their position, invented an interpretation of "share a protected characteristic" outwith the rest of the English-speaking world's understanding of the phrase.
The response to the reasonable pushback against this interpretation led to the deployment of Section 158 where similar wording is used. Combining this with Deloitte's alleged single programme for multiple PCs was presented as proof that "share a protected characteristic" does mean "have a protected characteristic" while ignoring the incoherence of this argument. (This being that positive action cannot be exactly the same for all PCs even the goals are the same and that we all have at least 6 PCs.)
And still they keep digging their hole. When will they stop? When they come out in Australia?
