I don't know the dates - we don't have them, so my point is that we don't know either way.
My main point though is that it doesn't matter. The request to the CCRC had to be made anyway. There is nothing strange or suspicious about deciding to use the new evidence there, along with other documents emerging then and since.
I'd have waited for Dr Jayaram to give his testimony at Thirlwall before going public with this one myself, and that was November. And if I already knew my international medical experts were analysing what went wrong in that case, again, I'd wait.
There is no obligation to throw everything relevant at a request to appeal. The only obligation is to get the request in within 28 days of sentencing.
I find that this happens a lot. A significant piece of information emerges. Someone somewhere online makes a point about process and others keep echoing it. But this one doesn't matter.
Why would it matter, if Lucy Letby's team had it and decided not to include it in the request for appeal on the retrial?
