The Duke of Sussex and six others have lost their High Court privacy case against the publisher of the Daily Mail and Mail on Sunday.
Judge Mr Justice Nicklin said the claimants had failed to prove the allegations of unlawful information gathering.
Prince Harry brought the case against Associated Newspapers, along with a number of well-known figures.
They claimed that the newspaper group used unlawful methods for getting information for stories, allegations which were strenuously denied by Associated Newspapers.
A spokesperson for the publisher described the judgment as an “overwhelming victory for the Daily Mail and its journalists”.
In a summary of his ruling, Mr Justice Nicklin concluded the allegations were serious and therefore required more convincing evidence before being proven.
He said the seven claimants could not rely on “suspicion, even where understandable”. Instead, he said they had to prove information had been obtained unlawfully.
