Andrew McFarlane, the UK’s most senior family court judge, said in his ruling on Wednesday that he found that through a network of servants and agents, Sheikh Mohammed had hacked the mobile phones of Princess Haya, her personal assistant, her solicitors Baroness Shackleton and Nicholas Manners, and two members of her personal security staff using “Pegasus” software licensed to Dubai and the UAE by an Israeli company.

“At no stage has the father offered any sign of concern for the mother, who is caring for their children, on the basis that her phones have been hacked and her security infiltrated. Instead, he has marshalled a formidable forensic team to challenge the findings sought by the mother and to fight the case against her on every point,” he added.

The judgment was released Wednesday, following a year-long reporting restriction that was lifted by the Family Division of the UK High Court.

In a statement Wednesday, Sheikh Mohammed contested the judgment, saying it was based on “an incomplete picture.”

“I have always denied the allegations made against me and I continue to do so. These matters concern supposed operations of State security. As a Head of Government involved in private family proceedings, it was not appropriate for me to provide evidence on such sensitive matters either personally or via my advisers in a foreign court. Neither the Emirate of Dubai nor the UAE are party to these proceedings, and they did not participate in the hearing. The findings are therefore inevitably based on an incomplete picture,” his statement said.

“In addition, the findings were based on evidence that was not disclosed to me or my advisers. I therefore maintain that they were made in a manner which was unfair,” it continued.

Dubai is one of seven emirates that make up the United Arab Emirates.

Because Sheikh Mohammed is the ruler of Dubai and the Vice-President and Prime Minister of the UAE, his lawyers argued that the Foreign Act of State (FAS) Doctrine — which prohibits a court from inquiring into the legality of acts made by a foreign state — undermined the UK High court’s jurisdiction in this case.

In January, McFarlane and Justice Martin Chamberlain ruled that the FAS doctrine did not prevent the court from adjudicating Princess Haya’s claims.

The Sheikh has repeatedly denied all claims raised in the ongoing case.
