Not if what Shoo Lee is saying is correct. He’s saying the persistent hypoglycaemia is understandable in the context of the treatment given, and that once the correct treatment was given to both babies the hypoglycaemia resolved as it should. While I understand people might think he’s biased, for someone of his expertise speaking on something as common as hypoglycaemia in preterm infants, I would think many many experts would have come forward if what he was saying was utter nonsense.
In which case, if we have a situation where we know these wildly inaccurate results can be reported by the lab, and the persistent hypoglycaemia itself wasn’t suspicious, then where does it leave things, because the evidence of a poisoner was arguably the most robust of all the evidence heard by the jury. And given the judge’s directions were such that any conclusions of deliberate harm could be used to add weight to the other charges, then it’s a house of cards waiting to fall.
