IANAL, but my understanding of 'the claimant's pleadings' is that it is the statements submitted in advance by SP's legal team, stating the facts of the case as they assert them.
So it appears that
“C referred to the “women’s prison incident”, that is the Isla Bryson/Adam Graham case.”
is a direct quote from SP's team. In other words, it was acknowledged in advance that the reference WAS to the Bryson case.
When SP denied that in her evidence, she was contradicting what her own team had stated.
Maybe it was a mistake and shouldn't have appeared in the pleadings, but it did, and the judge reacted to the legal team saying one thing, and the claimant saying something else.
There are lots of other things to criticise the judge for - e.g. for NOT picking up on DrU's inconsistencies - but in this very specific case, there was a discrepancy between pleadings and evidence and I suppose judges notice that kind of thing, and form opinions about credibility on them.
I am not defending him or his judgement, I'm just being objective about this specific point. The judge and judgement can be criticised on so many points, and I've joined in very enthusiastically on pointing them out, but some of the things he said he either had to say cos that's the law/procedure, or because they are factual.
I think we strengthen our support for SP by staying objective when looking at the judgement in detail.
But I admit that trying to stay resolutely objective in spite of everything is a 'me thing', Libran ascendant or something🙄. It's not lack of support. I assure you.
