Zeuhl, the judge said the evidence before him "appeared strongly to suggest that the Claimant was being blackmailed (although that is not how he put it himself). I hasten to add, as is obvious, that I cannot come to any final conclusion about it at this stage". But he took the preliminary step of suppressing G's name, which is normal: if the names of blackmail victims (real or imagined) were published, they would never dare go to the police.
He also said, in suppressing the name, "The Claimant is a married man with a family. It is well established, in such circumstances, that the court needs to take into account and have regard to the interests of the claimant’s family members, and their rights under Article 8 of the European Convention on Human Rights and Fundamental Freedoms."
All that sounds fair enough to me. Injunctions are temporary measures; the protection of possible blackmail victims, and their families, seems a reasonable step to take until the full truth comes out.
As to whether the woman was in it for the money, perhaps we won't see any tabloid stories this weekend headlined "Imogen Thomas: My Story". Or perhaps we will. In fact a story (I gather it named her but not him) had already appeared in the Sun, which was why the injunction was sought in the first place.
