Jason is recognised as a leading silk, specialising in public inquiries, inquests, public law and police law. He represents a range of clients, including central government, public authorities, police forces, coroners, and corporations, who are “very impressed by his client care” and note that he “Produces very effective legal submissions, and cross-examines with the panache of a top-flight criminal silk” (Chambers UK).
Jason often leads teams of counsel in complex, high-profile and sensitive investigations, inquiries and claims. His multi-disciplinary background (before taking silk, he was Junior Counsel to the Crown (A Panel); he currently sits as a Recorder on the South-Eastern Circuit) allows him to provide a service across a range of jurisdictions and fields of law: clients appreciate his ability to take a case from the investigatory stage (including giving advice on issues of criminal law such as corporate manslaughter and health and safety), advising or acting in any inquest or inquiry, appearing in any misconduct, criminal or disciplinary proceedings, and then handling any civil proceedings (including appellate proceedings to the Supreme Court).
He has provided this end-to-end service in a number of the most prominent cases of the last two decades. His caseload has included: the Stephen Lawrence Inquiry, the Hutton Inquiry, the Shipman Inquiry, the 'Phone Hacking' Claims, the Hillsborough Inquests, the Independent Inquiry into Child Sexual Abuse, the Grenfell Tower Inquiry.
Jason is the Head of Chambers of 5 Essex Court
Jason has appeared in most of the significant public inquiries of recent times: he has now appeared in 16 public inquiries, mainly on behalf of central government or other public authorities, or as counsel to the inquiry. He is ranked as a leader in this field by both of the major directories, sources noting that “…Jason can do everything. He is a lateral thinker and tactician and will usually think of a solution however novel the situation” (Chambers UK).
