(a) the significance of Justine Campbell's emphatic testimony that [Darren Campbell] had an injury to his right leg (when no evidence of such an injury was observed either in the police photographs, or by Dr Kain);
(b) the significance of the evidence of Dr Kain that an injury to the left leg, when sustained, would (at most) have been 1 cm in length, when assessing the prosecution's claim that Justine Campbell could have been confusing that injury for the 3 - 4 cm injury which she described;
(c) the significance of Dr Kain's evidence about the likely extent of bleeding of the injury which he saw, when compared to Justine Campbell's evidence about the extent of bleeding which she saw;
(d) the importance, or otherwise, of the absence of stitch marks surrounding the scar which Dr [Kain] observed; and
(e) the possibility that Justine Campbell was mistaken about which leg was injured, and the extent of the injury, and the impact which such mistakes might have upon her credibility as a witness on the whole.
