Year of Call - 2000

Year of Silk - 2023

Full Profile

Maria was appointed King’s Counsel in 2023. She is the first female silk, and the first home-grown silk, in the history of Church Court Chambers.

Maria prosecutes and defends the most serious, sensitive, and complex of criminal offences. Her practice includes murders, large-scale frauds and confiscation proceedings, historic rapes, child abuse and high-profile sexual offences, road traffic fatalities, multi-handed drug conspiracies and international importations.

Prosecuting and defending gives Maria a comprehensive and tactical viewpoint on every case she is involved in.

She is instructed regularly on a private basis to defend complex sexual offences due to her considerable level of expertise in this area.

Maria is public access accredited and accepts direct instructions from members of the public:

Maria’s practice also includes prosecuting and defending regulatory crime: environmental offences, health and safety breaches by corporations, local authority prosecutions and breaches of High Court injunctions.

Maria is well known for her meticulous preparation, fearless approach to each case and persuasive style in Court. She has excellent legal skills, intelligent case planning and full commitment to each case she undertakes. She is an excellent communicator who holds the confidence of each client and the Court.

When she is not prosecuting or defending cases, Maria sits as a Judge in the Crown Court [a Recorder] and in the Magistrates Court [a Deputy District Judge].
