Mastic, Inc. was a nonunionized contractor engaged in the insulating and weatherproofing business. Parran was its general manager and Ventimiglia (D) its labor relations advisor. Mastic got a job as a sub for a general who was a unionized company and needed to get union cards for its workers. Martin, the business agent for Local No. 80, complained to Mastic that its workmen were carrying cards issued not by him but by Ventimiglia who was then working for Mastic but who had earlier been the business agent for the union. After discussions, Martin was persuaded by Ds to issue working cards to Mastic's employees for which Ds agreed to pay Martin $100 each month. Martin did issue working cards signed by him and then got several monthly payments from Ds. Ds were brought to trial and acquitted of the substantive offenses but convicted of the conspiracy charges. This appeal followed.
