On the final day of evidence, Harry’s attorney grilled former Daily Mirror royal correspondent, whose byline appears on several of the 33 articles cited by Harry as examples of unlawful intrusion.
The lawyer suggested that some of the information in her stories came from phone hacking.
“It absolutely didn’t,” responded witness.
Piers Morgan (EIC) has denied knowing about phone hacking at the Mirror.
However, Mirror Group has previously paid more than 100 million pounds ($125 million) to settle hundreds of unlawful information-gathering claims.
Harry was not at Court on Thursday.
He spent a day and a half in the witness box on Tuesday and Wednesday answering questions.
Harry alleges that the Mirror newspapers hacked phones, bugged vehicles and used other illicit methods to obtain personal information.
He said the intrusion poisoned relations with friends, teachers and girlfriends — and even caused friction with brother – and led to “bouts of depression and paranoia.”
Mirror Group Newspapers has apologized for one instance in which it hired a private investigator to dig up dirt on Harry, which was not among the claims he has brought.
Harry is one of four claimants whose are being heard together. Hearings are due to last until the end of June, with the judge likely to deliver his ruling several weeks later.
He is also suing two other newspaper publishers over alleged hacking.
