By Dan Levine SAN FRANCISCO (Reuters) – A U.S. appeals court on Thursday dismissed federal wiretap claims against Facebook Inc and Zynga Inc in a civil lawsuit over disclosure of user information to advertisers. In a separate ruling, the 9th U.S. Circuit Court of Appeals also revived breach of contract claims under state law against Facebook over the information disclosures. Representatives for Facebook and Zynga could not immediately be reached for comment. Users of Facebook and Zynga filed separate class action lawsuits against the companies in 2010 that have been consolidated on appeal.
