If we had irrefutable evidence, as claimed, you'd think City's legal team would know if it hit home or not. If it was a finely balanced point of law then reading it might be awkward. I am more confident now than when I was before, particularly as the media have for the first time been completely silent on the subject.
i imagine they are weighing up the evidence on each side and thinking long and hard about what material weight to assign. The closer it is the longer it takes and neither side are likely to have a clue what a third party thinks.
