Issues included the way in which the original conviction could be used in the murder trial and complicated issues of medical causation.

R v MP (2018)

R v KC

Successful defence (with Andrew Haslam) of a man accused of murdering an older male who had abused the accused sexually when the accused was a child.

Led Keith Thomas of LT Law, Carlisle. Defending. Secured the acquittal of a man charged with the manslaughter of his four-week old baby. During the 2 1⁄2 week trial, the Prosecution relied upon a fracture to the child’s skull, along with what the experts termed a “modified triad” of internal head injuries – subdural bleeding, a swollen brain, and bleeding within the sheath of the optic nerves – as being diagnostic of non-accidental traumatic causation, and alleged that only the father had the opportunity to assault his child in the period immediately before death. Defence case was that the fracture might have happened after death, in which case the modified triad not conclusive proof of non-accidentally caused trauma and, in any event, if non-accidental, there was another potential culprit.
