A federal judge dismissed a case brought by former Apollo Global Management chief executive Leon Black alleging that his former partner and others conspired to destroy his reputation and push him out of the firm.

Black last October filed a civil RICO suit in the Southern District of New York in which he accused Guzel Ganieva, a former model with whom he had a yearslong affair, and her law firm of conspiring with a list of unnamed individuals to publicly accuse him of rape and harassment.
