If you read Neil's post, He believes its enough for a fresh appeal. So that is allot to debate if you ask me. Neil is cautious but I am convinced it will get Jeremy back to the court of appeal.
However I can understand why those who have not seen what I have cannot appreciate it. 
Yeah I kinda get all of that, people certainly can't comment on something that they haven't seen, well at least not with any authority.
NGB's view on something is perhaps of interest but hardly anything more, he doesn't have a good track record in this case of his belief of 'grounds for appeal' coming to fruition.
The 2012 submission was a strong case, compelling, almost a dead cert. In fact it wasn't going to go to another appeal, the charges were simply going to be dismissed. The CCRC decided otherwise and NGB then declared that the tests were incomplete. Clearly it was the CCRC's fault for dictating a deadline.
I don't actually believe NGB thinks Jeremy is innocent but rather he thinks there is a legal argument against his convictions.
I'm certainly not calling NGB out in any way or asking him to explain his position, nor indeed do I have any intention of being derisive towards him and I hope this isn't taken as such. We all have our opinions, I'm sure he'd be the first to agree.

Regarding David's "new" evidence, I'm of the opinion that it's nothing of the sort, it may be another angle or 'Mikeism' theory which hasn't previously been presented, but highly subjective and requires the reader to have a leap of faith in order to entertain.
I don't buy the secrecy for the benefit of reducing the CPS's ability to prepare a rebuttal, that sounds somewhat delusional to me. It also appears to me that David is desperate for recognition and fame, why else boast about something which he has decided not to disclose?
I believe that this will all amount to nothing, time will tell, but how long do we give it.
Can somebody remind me in a years time and we'll reassess.
