Have recently read a splendid article by
Mark Roodhouse on the involvement of Anglican radicals in the Chatterley trial of 1960. It explores one of the early episodes in the turn towards liberalisation of the law in the Sixties, and the limits of Anglican acquiescence and/or co-operation with it.
It's in the
Journal of Ecclesiastical History, 59; 3 (July 2008), 475-500 (available
online, by subscription.).
