PJS Supreme Court decision probably the final ruling in celebrity injunction case
By Juliet Bremner: ITV News Correspondent
The Supreme Court has ruled that a celebrity at the centre of a media blackout can not be named.
This is the latest and probably the final ruling in a series of court cases involving allegations that the celebrity, who is part of a well known couple, had an extra-marital affair.
The injunction bans the media in England and Wales from naming the person except by the initials PJS. It will now remain in place until there is a full trial for breach of privacy.
In today's judgement four out of five law lords agreed that it was not in the public interest because neither of the well known couple held public office.
They also disagreed with the argument that the couple had cultivated a misleading public impression of a faithful relationship.
They said an interim injunction would stop further invasions of privacy against them and their young children.
The Sun on Sunday newspaper, which planned to run the story, originally fought the ban on the grounds that it was in the public interest.
Despite an injunction, the story appeared in publications in the United States, Canada, Ireland and Scotland. It was also widely reported on social media.
News Group Newspapers, which owns the Sun on Sunday then argued that the details were so widely known the injunction made no sense.
