A lawsuit filed by a conservative think tank aimed at exposing Prince Harry’s immigration records is kaput after a judge closed it on Monday, according to court records obtained by Newsweek. The magazine reported that Judge Carl J. Nichols had sealed his order, leaving it unclear which way he ultimately ruled on the case. A lawyer for the Heritage Foundation acknowledged to Newsweek that they had seen that Nichols had issued a sealed ruling. “We know nothing about how the judge ruled,” Kyle Brosnan added. The organization sued the Department of Homeland Security earlier this year to find out if Prince Harry had improperly been granted a U.S. visa despite publicly admitting that he had used cocaine and other drugs, arguing there was “immense public interest” in getting to the bottom of the question of his potential “preferential treatment.” Critics have dismissed the lawsuit, which was filed after the department rejected the foundation’s Freedom of Information Act request for the Duke of Sussex’s immigration records, as political theater.
