The U.S. Court of Appeals for the Fifth Circuit weighed Monday whether a $57 million forfeiture order imposed on AT&T by the Federal Communications Commission violates the Constitution, with the company pointing to a recent landmark U.S. Supreme Court ruling to bolster its argument.

AT&T argues that the FCC’s forfeiture order—following accusations that the telecommunications giant mishandled customers’ location data—violated the company's Seventh Amendment right to a jury trial when a financial penalty can be awarded. Last summer, the high court held in U.S. Securities and Exchange Commission v. Jarkesy that the SEC must seek civil fines in court rather than through in-house proceedings.
