The UK tabloid's partial triumph for Prince Harry in the London trial would be fleeting, as the Duke of Sussex may be back in the High Court as soon as January.
The court concluded that Harry can proceed with portions of his case against Rupert Murdoch's newspapers, but charges of decades-old phone hacking were dismissed for being submitted too late.
The court also dismissed one of Harry's core allegations, that a "secret deal" had been reached between Buckingham Palace and Murdoch's media business to keep the illegal hacking of royals' cell phones quiet.
According to ITV journalist Rebecca Barry, News Group described it as "a significant victory" that "substantially reduces the scope of his legal claim."
But this legal struggle is far from done, she added. Prince Harry might go back in the High Court in January for a trial, charging The Sun of severe unlawful behaviour."
From the mid-1990s until 2016, Harry is suing News Group Newspapers (NGN) for claimed breaches of privacy by its tabloids, the Sun and the now-defunct News of the World.
It is one of four petitions brought before the High Court by the 38-year-old prince, who currently resides in California with his wife Meghan and their two children. He characterises the legal efforts as a mission to make tabloid leaders accountable for lying and covering up widespread misbehaviour.
