Career

Biography

Called to the Bar in 1999.

A powerful and highly persuasive trial advocate, Peter is also a patient, authoritative, yet unstuffy adviser in all aspects of criminal law. He has a reputation for meticulous trial preparation.

Peter’s trial work includes murder, attempted murder and manslaughter as leading junior, junior and sole counsel.

Over the past 25 years, he has also represented many defendants facing the most serious crimes of a sexual nature, whether historic or recent.

Peter has also undertaken a considerable amount of Court Martial work, representing serving members of the Army, Navy and Air Force, both in the UK and overseas.

​His practice is, nowadays, exclusively in criminal defence. However, Peter has in the past, prosecuted trials involving sexual violence and other serious violence towards children. His most recent prosecution work was in St Helena’s Supreme Court in the South Atlantic, prosecuting on behalf of the island’s Attorney-General.

​Peter is particularly adept at working with vulnerable people, including young defendants and complainants, as well as with people suffering with mental health difficulties.

Whilst he enjoys the rough and tumble of trial advocacy, he is equally at home in the Court of Appeal and has a significant and successful track record when appearing in and advising on appeals against both conviction and sentence.​

Peter has occasionally taught advocacy at the University of Law; he has also taught Administrative Law at undergraduate and post-graduate level and lectured on Criminal Law to various Law Societies.

Peter plays a very active role in the administration of chambers; he is chambers’ treasurer and is a member of the pupillage committee.

Being Australian, he is a passionate follower of cricket, but can easily be persuaded to watch just about any sport.
