IMO the appeal will go nowhere. It's not even worth talking about. The fact that GBC has been found guilty of murder and is now in jail for at least the next 15 years is all that matters. It won't bring Allison back but justice has been served for her and her family.
I completely agree with you Makara. I refuse to get worked up about the appeal - it is BS and is being done as a matter of course, but Justice Byrne is the best of the best and I will eat my proverbial hat if any appeal judges found that he erred in giving directions to the jury. With respect to the appeal point about the scratch evidence and experts, I see that a similar ground was relied on in Sica's appeal in relation to expert evidence, and they were sent packing.
I remain thrilled that GBC has been found guilty and is where he belongs and will be there for a very long time
