Prince Harry and the six other claimants in the case will pay £9.54 million in legal costs initially after losing their lawsuit against Associated Newspapers Limited, the publisher of the Daily Mail.
The group of claimants also included Elton John, Liz Hurley and Baroness Doreen Lawrence. Judge Nicklin dismissed all of the group's claims last month.
Total costs exceed £34.5 million
Associated Newspapers Limited said its total legal costs exceeded £34.5 million. However, the full amount will not be paid immediately.
The publisher sought more than £9.9 million as an interim payment. Lawyers representing Harry and the other claimants argued that the initial payment should be slightly more than £7.9 million.
The claimants' allegations
The claimants alleged that unlawful information-gathering activities had been carried out within the publisher's organisation over a period of about 30 years, beginning in the early 1990s.
The allegations included the interception of voicemail messages, the tapping of landlines and the use of methods described as obtaining information through deception. The claimants alleged that private investigators, freelance journalists and Associated Newspapers Limited employees were involved in these activities.
Associated Newspapers Limited strongly denied the allegations.
Court finds allegations unproven
In his 436-page judgment, Judge Nicklin concluded that the claimants had failed to prove any of their allegations of unlawful information-gathering, including phone hacking.
After the judgment was delivered in July, Associated Newspapers Limited described the outcome as an "overwhelming victory" for the Daily Mail's journalism and a "magnificent vindication".
The publisher also described the judgment as a "devastating critique" of an attempt to destroy the reputation of a newspaper and its journalists, editors and executives.
Under the final costs order, Harry and the other claimants will have to make the initial payment toward Associated Newspapers Limited's legal costs.
