Experience

Matthew is experienced in leading teams through every level of litigation from the early stages of pre-charge investigation and trial, through to the Court of Appeal, and the Supreme Court. He is one of a very small number of advocates who has been instructed in both the European Court of Human Rights and the International Criminal Court in The Hague. He is frequently instructed in cases because they are factually complex and / or involve novel or unusual points of law.

He has been leading counsel in major fraud and terrorist trials; large civil claims for damages; public law challenges to policing and government powers, financial, regulatory and disciplinary proceedings (including sports tribunals); challenges relating to freedom of expression and political protest.

Matthew’s trial experience in high profile cases has included cross-examining police officers accused of serious misconduct, Al Qaeda supergrasses, MI5 and MI6 operatives, politicians, tabloid editors and journalists, as well as a wide range of scientific, medical, financial and academic experts.
