This post asks about the law jurisdiction of England & Wales.
As I understand it, and I am happy to be corrected on this point, for a written statement to be libellous, it must be published to a third party (i.e. a party other than the claimant).
Here is my scenario:
In an online chatroom (Chatroom C) on a website with many users (Website D), there are only two male users, A and B, and no other user is ever, or will ever, enter the chatroom or know what has been said in the chatroom.
During a heated argument between A and B, A falsely accuses B of a crime, and that accusation never leaves Chatroom C. Assume A’s accusation is a statement capable of causing serious reputational harm.
B says he will bring a claim of defamation against A. A says that he did not publish his false statement to a third party. He only communicated it to B. B then responds that, actually, he did communicate it to three third parties, A’s internet service provider, B’s internet service provider and Website D, because, B furhter asserts, that they can all see what has been said in Chatroom C, which means that his claim of libel is still actionable.
Who is right in this situation, A or B?
