Old Square Chambers‘ members regularly appear in the appellate courts, test cases, and factually and legally complex trials; and the set is increasingly acting for more than one party in challenging cases, while also experiencing larger volumes of sensitive investigations. In the Court of Appeal, four silks and two juniors from chambers appeared for various parties and intervenors in a test case on whether foster carers have worker status (NUPFC v Certification Officer and others), namely: Lord Hendy KC, Ben Collins KC, Ben Cooper KC and Katharine Newton KC, along with senior junior Robert Moretto and Madeline Stanley. Betsan Criddle KC took silk in March 2022. Cooper KC also successfully represented both the claimant in Forstater v CGD Europe & others, a high-profile case concerning protection against discrimination in employment for holding gender-critical beliefs; and barrister Allison Bailey in her claim against her chambers for discrimination on similar grounds; however in that case the claim against co-respondent Stonewall, represented by Ijeoma Omambala KC and Robin White, was unsuccessful.
