Thursday 10 September 2026 | 6.30pm

Lambeth Town Hall, 1 Brixton Hill, London SW2 1RW (Nearest Tube: Brixton)

Fifty years ago, the Oval Four campaign titled Cause for Concern was launched at a public meeting at Lambeth Town Hall. The event became a powerful call to action against the wrongful conviction, harassment, and framing of Black men by corrupt police officers.

Five decades later, we are returning to the exact same venue to launch a definitive policy report, Trew’s Law: The Case for Automatic Reviews of Imprisoned Police Officers’ Files for Miscarriages of Justice, based on research by the York Law School and the Centre for Applied Human Rights at the University of York and APPEAL, the report is authored by Matt Foot, Dr Joanna Gilmore, Mya Imadojemun and Dr Mattia Pinto.

The systemic failures that enabled these injustices have never been fully addressed in law. This event marks an important opportunity to reflect on the past and push for meaningful reform.

Registration is free, but places are limited. Please reserve your ticket in advance.
