"At the end of the day ... it is for to you decide how much weight you put on the evidence of Maria Vervoort and I know you will consider it very carefully both in its own right and from the assistance you will get from the other evidence which forms part of a broader picture."
"It will usually be wise for the Court of Appeal in a case of any difficulty, to test their own provisional view by asking whether the evidence if given at trial, might reasonably have affected the decision of the jury to convict. If it might, the conviction must be thought to be unsafe."
"Wherever fresh evidence establishes that a material prosecution witness told a lie, the question arising for the appeal court's determination is whether that realistically places the appellant's guilt in reasonable doubt. That necessarily must depend upon all the evidence in the case. However barefaced the lie and however central to the prosecution case the witness who told it, the Court of Appeal is bound in law to address that question. Even in the case of ... murder it cannot be right to allow an appeal, without more, simply on the basis that the State's main witness has been shown to have told an outright lie. The court is not in such circumstances exonerated from undertaking its analytical task. And if it remains sure of the appellant's guilt and upholds the conviction, the court is not thereby depriving the appellant of due process."
