You will see in their appeal document that they clearly state:
"Secondly, on an appeal the Court does not hear the evidence again. That means that in a case like the present, where the decision is based on the judge’s findings about disputed questions of fact, it is not easy to overturn those findings on appeal. That is not only because the trial judge has had the advantage of seeing the witnesses giving their evidence.
As Lewison LJ put it at para. 114 of his judgment in FAGE UK Ltd v
Chobani UK Ltd [2014] EWCA Civ 5:
“Appellate courts have been repeatedly warned, by recent cases at the
highest level, not to interfere with findings of fact by trial judges, unless
compelled to do so. This applies not only to findings of primary fact,
but also to the evaluation of those facts and to inferences to be drawn
from them. …
The reasons for this approach are many. They include
(i) The expertise of a trial judge is in determining what facts are
relevant to the legal issues to be decided, and what those facts are
if they are disputed.
(ii) The trial is not a dress rehearsal. It is the first and last night of the
show.
(iii) Duplication of the trial judge’s role on appeal is a
disproportionate use of the limited resources of an appellate court,
and will seldom lead to a different outcome in an individual case.
(iv) In making his decisions the trial judge will have regard to the
whole of the sea of evidence presented to him, whereas an
appellate court will only be island hopping.
(v) The atmosphere of the courtroom cannot, in any event, be
recreated by reference to documents (including transcripts of
evidence).
(vi) Thus even if it were possible to duplicate the role of the trial
judge, it cannot in practice be done.”
I get that many people think Amber was young innocent girl who was too in love to leave and who had no choice due to her trauma to do anything but stay and spend 6 years being beaten to an inch of her life over and over and raped repeatedly by a violent, violent predator and sexual offender who wouldn't allow her to work or wear anything but modesty clothes and that is all there is to it. I realize we hae zero in common in our perspectives and these discussions are pointless at this point. I have listened to hours of recordings and looked at mountains of exhibits and documents and nothing it going to get me to ever see your point of view.
All the best.
