Notable Sexual offences cases

R v WA

Representing a man charged with historic rape allegations where there was substantial evidence to cross-contamination of witness accounts and police malpractice.  The submission that there was no case to answer succeeded.


R v DH

Represented a music teacher at a public school who had sexually abused pupils over the course of his career.


R v W

Represented a 13 year-old defendant accused of rape and serious sexual offences against children aged 4-14 who lived on his street and attended his school.  There was considerable hostility against him and his family in the community leading to demonstrations and extreme pressure being placed on all parties in the case. The trial was beset with difficulties and the Judge, perhaps understandably given the emotive nature of the allegations and the vulnerability of the witnesses, was in danger of losing sight of the needs of the defendant (immature, suffering from ADHD and a personality disorder).  Nick had to ensure special measures were put in place for ‘W’ so that he could understand proceedings and engage in his trial.   This led to direct conflict with the Judge and his views on how this reconciled with the needs of prosecution witnesses and how the case should be conducted.  Throughout the trial Nick had to warn the Judge, politely but firmly, against the dangers of exceeding his authority and being perceived as partisan.  Following days of deliberations the defendant was acquitted on all counts.
