A Manhattan federal judge has dismissed a $100 million lawsuit in a family dispute involving the Sapir Organization.

The ruling, from U.S. District Judge Ronnie Abrams of the Southern District of New York, last week tossed CEO Alex Sapir’s sole federal claim for misappropriation of trade secrets in the suit, which accused his former business partner and ex-brother-in-law, Rotem Rosen, of a wide-ranging campaign to extract money from the Sapir Organization and usurp its advantage in the real estate industry.
