The case has been wending its way through the legal system since April 2010, when GS was charged with nine counts of publishing an obscene article contrary to section 2(1) of the Obscene Publications Act 1959, and one count of possessing an indecent image.
What was particularly innovative was that the material in question was a series of text logs of online chats between GS and one other individual.
Initially, the legal reaction was that such a case could not possibly succeed - and that was pretty much the view of the judge who threw it out when first it arrived at Maidstone Crown Court in November 2011.
But that was before an appeal brought by the prosecution in February of this year, and the appeal court ruling in which three appeal judges - Lord Justice Richards, Mr Justice Kenneth Parker and Mr Justice Lindblom - ruled unequivocally that publication to an individual did fall within the meaning of the OPA.
Their judgment was published in full, earlier this week, by blogger Obscenity Lawyer, a solicitor and one of the UK's leading legal experts providing advice to defendants on matters of obscenity and extreme porn.
