A specialist criminal law barrister, almost all of Piers’ work is for the defence, privately funded and legally aided, where he is regularly instructed in cases involving murder/manslaughter, death by dangerous/careless driving, arson, firearms, human trafficking, serious violence, all aspects of drugs possession and supply, fraud and regulatory disciplinary offences. Piers also undertakes all forms of criminal law before the Court Martial.

Piers is an authority on road traffic offences especially death by dangerous/careless driving. Piers possesses an LGV C+E licence (aka HGV Class One) permitting him to drive articulated lorries and has been instructed to represent lorry drivers who are involved in serious collisions during the course of their employment.

Although Piers is based in the South West, he is happy to travel, and frequently does so, throughout the country in order to represent defendants wherever their case may be heard.
