I’ve no idea of the name of the shopworker who was busted. The two other JPs must have been named in the trial transcript but I haven’t got a record of them.

However, the Guardian article after the trial had ended does refer to the poetry reading on the beach: “David Field, another helper in the shop, was arrested while giving his weekly officially-permitted poetry reading on the beach. About 200 people heard him read a Ginsberg poem, and the policeman said some people in the crowd looked upset. The chairman of the magistrates on that occasion was not Mr Ripper, but Mr John Cuttress. Mr Cuttress said there was no evidence of annoyance to the public by the use of a word which was part of a published work by a recognised poet. He dismissed the case. The police were angry at being let down, and appealed. Lord Parker not only dismissed the police appeal, but said that the original case should never have been brought.”
