SAN FRANCISCO — A panel of the U.S. Court of Appeals for the Ninth Circuit on Wednesday rejected a bid by anti-abortion activists to block a fraud and racketeering suit by Planned Parenthood in a case centered on secretly recorded videos.

Writing for the unanimous panel, Circuit Judge Ronald Gould wrote that the district court properly denied an anti-SLAPP motion by the Center for Medical Progress, headed by anti-abortion activist David Daleiden, and other defendants.
