But clearly there wasn’t for the juries (for the offences they convicted her of) who heard all the evidence, which included dealing with some of the issues that have since been raised by the panel. From the article linked to above:
The “international panel” includes some high-flying neonatologists, and their opinions deserve to be taken seriously. Yet it is difficult to do so when they float ideas that have already been raised and refuted in court. They claim that the mother of Baby A passed her antiphospholipid syndrome (a rare blood disorder) on to the child, and he died of thrombosis as a result.
Aside from there being no physical evidence of thrombosis, Professor Sally Kinsey, a haematologist at Great Ormond Street Hospital, testified in court that blood tests proved that neither of the twins had antiphospholipid syndrome. The panel further asserts there is “no evidence” that Baby G was overfed, but the evidence shows she was being given 45ml of milk every three hours, each time on an empty stomach.
After projectile vomiting three times, she still managed to aspirate 45ml of milk through the nasogastric tube — and a further 100ml was aspirated later. As the neonatologist Dr Sandie Bohin explained in court, “basic arithmetic” shows that she was overfed.
