King Charles III's younger son made headlines earlier this year when he flew in from California to make an unexpected in-person appearance at the High Court in London for the case.
The prince and six other high profile figures including pop star Elton John launched the legal action last year after becoming aware of "compelling and highly distressing evidence that they have been the victims of abhorrent criminal activity and gross breaches of privacy" by Associated Newspapers Limited (ANL).
Lawyers for ANL -publishers of the Daily Mail and Mail on Sunday- had argued the claims against them had been brought too late.
But in a written ruling, judge Matthew Nicklin disagreed and said the case could go ahead.
The ruling is the latest chapter in Harry's turbulent relationship with the press, whom he holds responsible for the death of his mother Princess Diana in a 1997 Paris car crash as she fled paparazzi.
