Prince Harry and several other high-profile celebrities who lost a prominent High Court privacy case may face challenges in maintaining their litigation insurance coverage, following a recent ruling that criticized their conduct during the legal proceedings.

The group, which included figures such as Baroness Lawrence of Clarendon, Sir Elton John, and Liz Hurley, brought a case against Associated Newspapers, the publisher behind the Daily Mail and The Mail on Sunday. They had secured litigation insurance policies from a major British insurer, each providing up to £2.25 million to cover potential legal costs if the claim was unsuccessful. These policies were designed to protect the claimants from paying the publisher’s legal expenses, which were estimated to total as much as £50 million.

However, indications suggest that the insurers might seek to invoke clauses allowing them to withdraw coverage if the court imposes punitive costs—a possibility heightened by the recent judgment from Mr Justice Nicklin. His ruling sharply criticized some of the claimants' behavior during the litigation, leading legal experts to predict the likely awarding of indemnity costs. Such an award would override previously agreed-upon proportional cost limits and expose the claimants to significantly higher financial liabilities.

The litigation involved lawyers working on a conditional fee arrangement, commonly known as “no win, no fee,” where payment depended on a settlement or trial victory. To protect themselves from adverse cost orders in case of failure, the claimants entered into insurance agreements intended to cover the court-approved cost budgets determined before trial. If indemnity costs are granted, these budgets could be set aside, potentially increasing the claimants’ financial exposure beyond the limits of their insurance.

Paul Dacre, chairman of Associated Newspapers and former editor of the Daily Mail, stated that the publisher’s total legal costs could reach £50 million. Given that individual claimants were insured for up to £2.25 million each, the total coverage falls significantly short of this figure. The resulting gap, estimated at more than £34 million collectively, could become the responsibility of the claimants if insurers refuse to cover punitive costs or if they claim breaches of policy terms linked to the claimants’ conduct during the litigation.

Colin Campbell, a former High Court costs judge and consultant at the law firm Kain Knight, described the reported insurance coverage amounts as “entirely plausible” and noted that punitive cost awards generally provide grounds for insurers to repudiate coverage. He explained that an indemnity costs order would simplify Associated’s ability to recover a much larger share of its legal expenses, substantially increasing the financial risks faced by the claimants.

A source close to the claimants confirmed that Baroness Lawrence will not be required to contribute to the legal costs, indicating she received assurances protecting her from payment liability at the outset of the case. Prince Harry reportedly committed to ensuring she would not be financially impacted.

The case highlights the complex interplay between litigation funding, insurance agreements, and court rulings on costs, illustrating the potential consequences for well-known individuals engaged in high-profile legal disputes.
