Hi again Spitfire - my reading of the Court's 2002 judgement (particularly para 125) is that the AB stains were on the knicker fragment tested in 1997. On that basis, I consider that checks could and should have been carried out to verify the presumption that these stains came from Gregsten.
Whilst I believe the presumption would have been verified, the potential significance was and remains huge. If these stains do not tally with Gregsten, that would be strong evidence of another man or, at the least, contamination and the whole of the DNA case against Hanratty would collapse like a house of cards in a cyclone.
