On January 2, 1981, he was sentenced by Milton Pollack, of the U.S. District Court for the Southern District of New York, to four months in prison for fraud. Bronston had helped one company to get a contract for New York City bus shelters while having been retained by, and thus legally representing, a competing company.[5] On August 19, 1981, the conviction was upheld by the United States Court of Appeals for the Second Circuit.[6]
On June 18, 1981, Bronston's license to practice law was suspended by the New York Supreme Court, Appellate Division effective July 17. On March 5, 1985, the suspension was declared as terminated, effectively from September 17, 1984.[7]
