Posted this article earlier but I do highly recommend it as it discusses some points I haven’t seen discussed elsewhere. link
It seems the defence had at least one expert whose evidence would have supported them, so why not call?:
Dr Mike Hall, a retired consultant neonatologist and visiting professor in neonatal medicine, advised Letby’s legal defence team but was not called to give evidence at the trial. He said: “I feel a particular sense of injustice about Baby C because all four main prosecution witnesses [who gave evidence about the child] either directly or indirectly led the jury to believe that part of the cause of the demise was evidence from an X-ray taken on 12 June 2015. Letby had never been involved with that baby prior to that X-ray.”
Then there’s this - will be interested to see if any of the senior neonatologists mentioned feature at any new trial:
The allegation that Letby murdered babies by injecting air down their nasogastric tubes has, as the Guardian reported in July, been one of the lightning rods for the criticism from medical experts,* who described the theory as *nonsensical or “rubbish”, “ridiculous”, “implausible” and “fantastical”.
McDonald said: “Dr Dewi Evans appears to be shifting his opinion regarding one of the most fundamental aspects of the case, the medical evidence. I have now spoken, and have reports, from some of the most senior neonatologists in the country, and none of them has yet agreed with Dr Evans.
