Matrix Chambers has earned a ‘very good reputation’ in the field of immigration and asylum law, with its practitioners regularly acting in complex and novel cases involving high net worth individuals and national security issues. Nick Armstrong KC led Toby Fisher and Darryl Hutcheon in R (AH and IS) v SSHD, a significant challenge to individual immigration detentions that raised a wider systems challenge to the Home Office and Brook House immigration removal centre. Raza Husain KC is highly regarded for his work on the Rwanda litigation, having acted as lead counsel the litigation both prior and subsequent to the Safety of Rwanda Act 2024, up until the policy's demise at the end of the Conservative government. Christopher Buttler KC acted in VT v Commissioner for the British Indian Ocean Territory, a successful claim on behalf of 61 Tamil migrants seeking damages for their treatment in the British Overseas Territory with no population other than a joint US-UK military base. Eleanor Mitchell was also involved in key Diego Garcia-related litigation.
