Prince Harry has returned to a London court as his attorney fought assertions that the phone hacking lawsuits he, Elton John and other celebrities have brought against the publisher of The Daily Mail are based on forbidden documents. A four-day hearing resumed Tuesday in the case alleging Associated Newspapers Ltd. hired private investigators to illegally bug homes and cars and record private phone conversations. The publisher denies the allegations and is seeking to throw out the lawsuit, arguing the claims are too old and barred because they rely on information it turned over in confidentiality for a 2012 probe into media law breaking. The case also includes claims by actresses Liz Hurley and Sadie Frost.
