In this extended special edition episode, Dan Stilitz KC and Katherine Taunton explore the difficult recent case law on single sex spaces in the workplace: Kelly v Leonardo UK Ltd; Peggie v Fife Health Board and Upton; Hutchinson & others v County Durham and Darlington NHS Foundation Trust; and R. (on the application of Good Law Project Ltd) v Equality and Human Rights Commission [2026] EWHC 279. How did the Tribunal panels analyse the issues in these cases differently?  What guidance can employers take from them? What light does the High Court’s recent judgment shed on these difficult issues?
