Evidence – Similar facts. The claimants issued proceedings against the defendant Commissioner of Police for the Metropolis, seeking relief in respect of alleged false imprisonment, assault, racial discrimination and infringements of their human rights. They made numerous applications contingent on the admission of eleven incidents of similar fact evidence against individual police officers. The parties sought the determination of the admissibility of the evidence as a preliminary issue. The Queen's Bench Division found four incidents were admissible, as they passed the test set out in O'Brien v Chief Constable of South Wales Police ([2005] 2 All ER 931).
