 The indictment alleged that Dioguardi and others had extorted money from truck drivers in the New York City garment industry, and received bribes from employers in exchange for refusing to call strikes.Dioguardi's trial was due to begin in January 1957, but key government witnesses either refused to testify or recanted earlier statements implicating Dio in the labor rackets.Dioguardi sought lengthy delays once again prior to his trial, but the court refused to permit them and empanelled a special jury to try him.
