LONDON — Prince Charles today won a court judgment to block publication of further extracts from his journal, but the High Court ordered a trial to determine whether other journals should stay private — a decision that could compel Charles to testify.

Judge William Blackburne said Charles could claim damages for the publication of the Hong Kong journal by the Mail on Sunday newspaper, and seek a permanent injunction to protect that journal.

However, the judge said he was unwilling to bar publication of seven other journals reportedly sold by a former employee without knowing what they contain.

Charles, 57, sued the publisher of The Mail on Sunday, which in November published portions of the diary kept during a 1997 trip to mark the return of Hong Kong to China.

The prince's lawyers said the document, intended for distribution to a few close friends, was leaked by a former palace employee. They claimed invasion of privacy and copyright infringement.

The newspaper contended that publishing the diaries is in the public interest because they reveal the political beliefs of the man who would be Britain's head of state as king.
