What makes me think he didn't say it is that it would be so extreme a direction.What makes you think the judge didn't say that?
Seems entirely reasonable.
He shouldn't get to say whatever he wants and it stand, but then not be put under scrutiny by the prosecution
There is no statutory provision or case law that says whenever a defendant refuses to submit to cross-examination every single word of their evidence-in-chief must always be completely and utterly ignored. Considerations of degree and effect and circumstances must be taken into account.
And anyway look at how it has been reported: "(the judge said) he would direct the jury to give minimal weight to the evidence Gordon has already put forward."
The judge said basically that he would go to the absolute extreme, and he said so before he'd heard any submissions from any of the three parties regarding what direction he should give? That's unlikely IMO. Judges don't do that. They may say they are "minded". But they know the parties have a right to be heard.
See too the sentence "Judge Lucraft then clarified if Gordon’s evidence would continue".
It sounds to me that Tristan's cat may have got onto his keyboard. JMO
