Meghan Markle, 39, is suing Associated Newspapers Ltd (ANL) over the publication of parts of a handwritten letter to his father Thomas Markle, 76, in the Mail on Sunday and MailOnline in August 2018.
She says the use of the letter was a copyright violation, a violation of her privacy and a violation of data protection law.
His legal team had filed a request to postpone the trial in his privacy and copyright case, which was scheduled to begin on January 11 next year.
Last month a London court ruled that the Mail On Sunday could modify its file to include details of a recently published biography, Finding Freedom.
The judge, Judge Warby, told the court that earlier Thursday morning he had conducted a private hearing from which the press and the public were excluded.
He went on to explain in a public hearing by video link that the “main reason” on which the adjournment was requested was “a confidential reason”.
Allowing the adjournment request, Justice Warby said, “The correct decision in all the circumstances is to grant the adjournment request.
“This means that the trial date of January 11, 2021 will be set aside and the trial will be rescheduled for a new date in the fall. “
During the proceedings which are taking place via video link, Judge Warby also denied a further request from Meghan’s legal team to remove the inclusion of the recently published book Finding Freedom as part of the defense.
ANL dit Meghan et Prince harry “Cooperated with the authors… to publish their version of certain events”.
They say this is further proof of how Meghan has allowed elements of her privacy to enter the public domain.
However, Meghan’s lawyers deny that the couple have “collaborated” with the authors, Omid Scobie and Carolyn Durand.
The HarperCollins biography was published in August of this year.
The Duchesses’ legal team is appealing that the decision to include the book as part of the defense be overturned.
Meghan’s minor victory is just the latest fight in the ongoing legal action.
In August, a judge ruled to protect the identities of five of Meghan’s friends who gave an anonymous interview to People magazine.
Meghan is suing ANL for five articles in total – two in the Sunday Mail and three on MailOnline.
