Should government agencies have the authority to expand data breach reporting requirements for private businesses?
The Sixth Circuit Court of Appeals heard oral arguments in a legal challenge against a 2024 Federal Communications Commission rule governing data breach notifications. The pending regulation requires telecommunications providers to report breaches affecting 500 or more customers to the agency within seven business days.
Why it matters
This case tests the scope of federal oversight on data security for telecommunications providers, specifically regarding the breadth of reporting requirements and the interpretation of the Congressional Review Act. The outcome will determine whether these expanded mandates remain in effect for the industry.
The rule mandates that providers notify the Federal Communications Commission of breaches within 7 business days for incidents impacting 500 or more customers. This expands reporting requirements to include sensitive data such as Social Security numbers, email addresses, and biometric identifiers.
The players
Federal Communications Commission
The independent U.S. agency tasked with regulating interstate and international communications by radio, television, wire, satellite, and cable.
Ohio Telecom Association
The trade organization representing telecommunications companies that challenged the regulatory reporting requirements.
Sixth Circuit Court of Appeals
The federal appellate court currently adjudicating the legality of the new data breach notification mandate.
The details
The legal dispute centers on the interpretation of the Congressional Review Act, a law that allows Congress to review and potentially overturn new federal regulations. The Federal Communications Commission rule expanded the types of customer information classified as protected data, moving beyond traditional call records and billing information to include personally identifiable information. The court is evaluating whether the agency acted within its authority when adopting these expanded mandates.
Timeline

The Tech Race
This litigation serves as a critical test of the Congressional Review Act as it applies to modern digital privacy mandates. It follows a pattern of heightened judicial scrutiny regarding how federal agencies balance broad cybersecurity oversight with existing statutory limitations.
If upheld, the rule forces telecommunications providers to standardize how they handle and disclose breaches involving sensitive personally identifiable information. Customers may receive more consistent and timely breach notifications as providers adjust their reporting workflows to meet the seven-day window.
The takeaway
The court's decision will clarify the extent of federal authority to mandate rapid reporting of security incidents in the telecom sector. Observers should track the Sixth Circuit docket for the forthcoming opinion, which will set a precedent for how future data security rules are applied to consumer information.
