Chi, like Closer, is published under the Mondadori publishing house owned by former Italian Prime Minister Silvio Berlusconi. Chi is also the same magazine that, in 1997, published photos of Prince William's mother, Princess Diana, dying in a tunnel in Paris after a high-speed car chase with paparazzi that ended in her death at age 36.
The royal family has evoked the memory of Princess Diana in seeking to block the photos and pushing for criminal charges.
"The incident is reminiscent of the worst excesses of the press and paparazzi during the life of Diana, Princess of Wales, and all the more upsetting to The Duke and Duchess for being so," the palace said in a statement last Friday.
The editor of Chi stood behind his decision to publish the photos, telling The Associated Press that he did not fear legal action and writing on Twitter that "not even a direct call from the Queen" could stop him from publishing the photos.
Likewise, the editor of the Swedish publication denied that the photos are an invasion of privacy for the couple. "It is nothing new to us to publish nude photos of celebrities on holiday," said Carina Lofkvist, the chief editor of the Swedish magazine, told the AP. "No one complains when they do and we print the photos."
Since the court ruling, the royal family has issued only a simple statement on the topic, in support of the court's decision.
"The Duke and Duchess of Cambridge welcome the judge's ruling," a representative for St. James's Palace said Tuesday.
The scandal broke while the couple were in Malaysia for the Diamond Jubilee tour, but Middleton and William remained mum on the photos while letting their lawyers do their talking. They departed from Tuvalu Wednesday on a commercial flight bound for home in the U.K.
Meanwhile in London, actor John Travolta, who has had his own issues with privacy, said he sympathizes with the royals and supports stronger laws to shield celebrities.
"This is the worst time to be famous," Travolta told the BBC.
