A Broward County man who bought $19 worth of chocolate treats in 2015 left Aventura Mall with a bitter taste in his mouth that's led to years of back-and-forth in a class action lawsuit over the privacy of information on his receipt.

The Florida dispute has tested the limits of consumer rights and might ultimately be destined for the U.S. Supreme Court.

The U.S. Court of Appeals for the 11th Circuit had already affirmed Dr. David S. Muransky's $6.3 million class action settlement against New Jersey company Godiva Chocolatier Inc. for allegedly printing more than five digits of his credit card on a receipt — in violation of the Fair and Accurate Credit Transactions Act, or FACTA. But six months on, the court put forward a fresh opinion, addressing conflicting rulings and dismissing objections from two class members.
