They are about twenty years out of date in that article with the standard of proof in criminal trials. The express test for the last couple of decades has been being ‘sure’ of someone’s guilt. It’s supposed to amount to the same thing as beyond reasonable doubt, but I don’t wholly agree. It’s definitely in the same ball park, but the previous test contains a qualification that the current one does not. So I think they are slightly different. Otherwise, why change it?
In any event, that article is wrong as to what the stated burden is.
