It cannot be stressed just how ground-breaking this verdict is.
This is legal dynamite - and in one single judgment catapults the UK to the back of the queue on a range of international indices on freedom of speech.
The change to the law - or clarification as judges might describe it - came about in February when the Appeal Court ruled on a prosecution appeal in respect of an individual identified only as "GS".
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.
The judgment states (par 21): There could be no sensible reason for the legislature having excluded otherwise obscene material from the scope of the legislation, merely because it was likely to be read by, and therefore liable to deprave and corrupt, only one person...
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.
