Aug. 21 (UPI) -- Prince Harry, Sir Elton John, Liz Hurley and four others who accused the Daily Mail of improper reporting tactics and privacy violations have been ordered by the court to pay the publisher $13 million in legal costs by Aug. 28.

Judge Justice Nicklin ruled on Friday that the claims made by the claimants were "unreasonable to a high degree" and they should have to pay more than what was agreed upon previously. They have until Oct. 2 to file an appeal.

Nicklin dismissed the claims against Associated Newspapers Limited, the publisher of the Daily Mail, last month.

The claimants were insured to cover up to $22.1 million of ANL's legal costs. ANL says it incurred about $47 million in legal costs.
