In London, Penguin Books was prosecuted under the Obscene Publications Act of 1959 for publishing D.H. Lawrence's novel "Lady Chatterley's Lover," which had been banned in Britain since 1928. The defense called thirty-five literary witnesses, including E.M. Forster and Rebecca West, to testify to the novel's artistic merit. The jury's acquittal was seen as a landmark moment in the liberalization of British culture and the end of Victorian-era censorship.

The Chatterley trial marked a turning point in British literary culture, ending the era in which poetry and fiction could be effectively suppressed by obscenity law. The trial's focus on literary merit as a defense directly influenced how courts treated poetry in subsequent cases, and it liberated British poets from the shadow of censorship that had constrained writers from Lawrence's generation onward. The case became a reference point in the poetry of the 1960s movement that rejected sexual and formal repression.
