Mealey's (July 10, 2019, 9:22 AM EDT) -- ATLANTA — An 11th Circuit U.S. Court of Appeals panel on June 24 ruled that a federal district court did not abuse its discretion in allowing the testimony of government prosecutors’ expert witness in a criminal suit against three parties alleged to have operated a massive Ponzi scheme because the court took the necessary curative measures to correct any potential issues for the jury (United States of America v. Joseph Signore, No. 16-11344, United States of America v. Laura Grande-Signore, et al., No. 16-11425, 11th Cir., 2019 U.S. App. LEXIS 18753)....
