Leon Black's lawsuit alleging a conspiracy to harm his reputation by his Apollo Global Management co-founder Josh Harris and ex-model Guzel Ganieva was thrown out by a federal judge in Manhattan.
U.S. District Judge Paul Englemayer called Mr. Black's racketeering claims "glaringly deficient in fundamental respects" in dismissing them with prejudice, meaning Mr. Black will not be able to refile them in an amended complaint.
Mr. Black had claimed Mr. Harris, Ms. Ganieva, and public relations professional Steven Rubenstein all violated civil racketeering laws by conspiring to destroy him personally and professionally.
The billionaire also accused the three, along with Ms. Ganieva's lawyers at Wigdor LLP, of defamation, breach of contract and unjust enrichment claims. Mr. Englemayer dismissed those claims but said Mr. Black could refile them in state court if he chooses.
Mr. Black and Ms. Ganieva have exchanged a nasty set of back-and-forth legal claims. Her initial allegations of sexual assault, first revealed in tweets in mid-March of last year, followed reports of Mr. Black's larger-than-expected payments of $158 million to Jeffrey Epstein for tax advice and financial services.
Mr. Black has accused Ms. Ganieva of extortion and denied the allegation that he sexually assaulted her. He instead characterized their relationship as a consensual affair, which started in 2008 and ended around 2014.
Following reports of his Epstein ties, Mr. Black stepped down as chairman and chief executive officer of Apollo and receded from roles including chairman of New York's Museum of Modern Art. His racketeering suit claimed Mr. Harris conspired with Ms. Ganieva to wrest control of Apollo from him.
