Okay, this is good. Very good.
For legal fans, and I know there are many here, this is a barrister doing his work for a respected think tank to dismantle the Equal Treatment Bench Book, rather than a hapless claimant.
The intro from a Senior Circuit Judge applies the usual masterful understatement:
Readers of Chapter 12 [Trans People] may perceive a lack of balance in its general tone and trajectory. 
108 paragraphs of dissection of all the things wrong with it, cross-referencing with all the cases where the police and courts have gone awry - Forstater, MacLachlan, Miller, the gang of transwomen in the Tube attack, the fined "is it a man or a woman?" Aspergers teenager. And references to the Reindorf report.
He's clearly been spending quite some time on this, and waiting for the Forstater appeal to conclude. Forstater's original loss may well have been the catalyst.
Judge's intro again:
In 2019, an Employment Tribunal ruled that Maya Forstater’s belief (held and expressed by her as a private individual) that sex is an immutable biological fact is ‘not worthy of respect in a democratic society’. Reading this, many thousands of reasonable people must have scratched their heads in bewilderment. Such a belief may have become, in very recent times, the subject of controversy, but how could it possibly be ‘not worthy of respect’? This decision has been overturned on appeal. The flawed reasoning which led to it is meticulously analysed in this new Policy Exchange paper by barrister, Thomas Chacko. Further, his analysis led him to an issue of wider and deeper concern than one tribunal’s legally incorrect decision: the nature and use in court of the Equal Treatment Bench Book (ETBB) - a document issued by the body responsible for training judges, the Judicial College.
