The Supreme Court rejected constitutional challenges from Verizon and AT&T to more than $100 million in combined fines imposed by the Federal Communications Commission in an 8-1 decision on Thursday.

Chief Justice John Roberts wrote the majority opinion, ruling that the companies are not entitled to a jury trial to contest the penalties. The fines relate to how the telecommunications companies handled customer location data.

The case centered on whether the Seventh Amendment's guarantee of jury trials in civil cases applies to FCC enforcement actions. Verizon and AT&T argued that fines of this magnitude entitled them to have a jury evaluate the evidence and determine appropriate penalties. The Supreme Court disagreed with this interpretation, affirming the FCC's regulatory authority to impose financial penalties through administrative processes.

The decision significantly strengthens the FCC's enforcement capabilities and establishes an important precedent for how federal regulatory agencies can impose penalties on companies under their jurisdiction. The ruling confirms that agencies can continue using administrative procedures rather than jury trials when levying fines for violations of regulations they oversee.

Only one justice dissented from the majority opinion. The court has not yet released details about which justice broke from the majority or the specific reasoning behind the dissent.

This ruling resolves a legal battle that has worked through the court system as the telecommunications companies sought to overturn or reduce the substantial penalties. The decision represents a significant win for the FCC in defending its enforcement authority against constitutional challenges from major corporations.

The case highlights the ongoing tension between corporate defendants seeking traditional legal protections like jury trials and federal agencies arguing that regulatory matters require specialized administrative proceedings. The Supreme Court's decision favors the regulatory approach, allowing agencies greater flexibility in implementing enforcement actions.

The fines against Verizon and AT&T are among the largest penalties the FCC has levied against telecommunications companies, making this case particularly significant for the industry. The ruling may also have broader implications for how other federal agencies conduct enforcement actions against regulated entities.

The telecommunications companies had argued that the magnitude of the fines—exceeding $100 million combined—warranted the constitutional protections afforded by a jury trial under the Seventh Amendment. However, the Court determined that the FCC's administrative process provided sufficient protection and that jury trials are not required in regulatory enforcement contexts.

This decision gives the FCC and potentially other federal agencies more certainty in pursuing enforcement actions. Companies challenging future regulatory fines will face an uphill legal battle in arguing that jury trials are constitutionally required. The Supreme Court has effectively endorsed the modern administrative state's approach to regulating major corporations in specialized areas like telecommunications.
