Separately on Michael Hall, because it's an interesting question.
You often see the complaint that some of the defence witness's findings have already been tested in court, as if this means the panel was wrong to publish them. You need to think about what you are saying here.
Hall's point on some of the expert witness's findings already having been discussed at trial is true. Nobody denies this. It would be odd if they hadn't - plenty of the problems with the children's conditions and treatment were all too apparent. Hall's point and worry was that this may be an obstacle to using these conclusions in appeal.
That's technically possible, but an appeal permits the use of new argument (and could be granted on many grounds). There will be no problem using these reports in any retrial: the conduct of the first trial doesn't prevent that. But who would have wanted the expert panel to construct arguments that didn't overlap with anything said in court, as if they were playing a game instead of looking for children's causes of death?
Hall's other concerns are about cases where he can't see where the experts got some (significant but inessential) information. But these are also cases where he was missing information. In the case of baby O, that's the obstetrics notes, of course. We now know the opinion of the panel draws on specific obstetric expert opinion on what is available, so I'm sure that would reassure him. We have also learned, after he made these comments, that he thinks he was not given some key results from baby O's records.
Similarly with baby I, where he commented that certain information wasn't found at post-mortem, we had later newspaper reports revealing that it had. In any case, what he disputes are not the causes of death, or the assertion that these were natural deaths, but details on which the panel opinion doesn't rely. All a storm in a teacup which I'm sure would be resolved in the full reports
