On Monday, a privacy injunction preventing reporting of a story about the claimant since January, in which it is claimed the individual had had an extra-marital affair, was lifted by a panel of three judges at the Court of Appeal.
The judges decided that the story had already been widely reported in in territories where the court has no jurisdiction, and that it had become common knowledge.
However, following an appeal of Monday’s ruling, an interim reporting ban was put in place, which was due to expire today (Wednesday).
This was then extended by 24 hours, so the claimant can argue their case for another appeal at a hearing before the Supreme Court on Thursday.
An initial decision on whether PJS is indeed allowed to bring that appeal, and if so the subsequent appeal, are both expected to be concluded by lunchtime.
The story has led to debate over the viability of such orders in the digital age and the question of when information is in the public interest.
The Supreme Court has published information on its website about attendance at the hearing, saying that it was "expecting a large number of visitors to attend the hearing PJS v News Group Newspapers", that the hearing will start at 9.30am and finish at around 1pm, and that proceedings will be streamed via the Supreme Court website.
