The Queen came to the Duchess of Sussex’s aid in her legal battle against the Mail on Sunday on Wednesday by dismissing claims that she owned the copyright to a letter Meghan wrote to her father. Her Majesty’s lawyers intervened in the High Court case as the two sides locked horns over one of the final bones of contention. The Duchess’s former communications secretary, Jason Knauf, also “emphatically” denied having any copyright claim to the letter, landing a final blow to the newspaper’s case. Their interventions on Wednesday paved the way for Lord Justice Warby to award a summary judgment on the outstanding copyright claim and with it, further costs. The Duchess successfully sued Associated for breach of privacy and copyright relating to the publication of five articles featuring extracts of the letter in February 2019. In February, she won a summary judgment, a legal step negating the need for witness evidence, in relation to the privacy claim and the bulk of the copyright claim. One of the final issues on which both sides disagreed was whether the Duchess was the sole owner of the copyright of the letter, having admitted that she sought guidance from others, including Mr Knauf and her husband, Prince Harry. Associated suggested that the Duchess sought professional advice because she knew the letter would be made public and that it was intended for use as part of a media strategy to enhance her image. As a co-author, Mr Knauf’s role at Kensington Palace might have rendered the letter Crown copyright. However, the court heard that Mr Knauf had confirmed in writing, via his solicitors, that despite making a “very minor suggestion” that Meghan include a reference to her father’s ill health, he did not co-write the letter. As such, he said he had no wish to become a party to ongoing legal proceedings.
