Federal Communications Commission v. AT&T, Inc.

What is the scope of the FCC's authority to regulate telecommunications carriers, and did the Fifth Circuit correctly limit the agency's regulatory power?

Oral argument scheduled for April 21, 2026 at 10:00 a.m. ET

Background & Facts

The Federal Communications Commission (FCC) issued regulations affecting how telecommunications carriers like AT&T and Verizon operate. AT&T and Verizon challenged these regulations in the United States Court of Appeals for the Fifth Circuit, arguing that the FCC exceeded its statutory authority. The Fifth Circuit, in a decision issued August 22, 2025, ruled in favor of AT&T and Verizon, striking down or limiting the FCC's regulations. The FCC then petitioned the Supreme Court for review, and the case was consolidated with a related case (No. 25-567) for briefing and oral argument.

This consolidated case presents fundamental questions about the proper scope of regulatory authority granted to federal agencies under telecommunications law. The lower court's decision appears to have restricted how the FCC can implement its statutory mandate, prompting the government to seek Supreme Court review of that limitation.

Why This Case Matters

This case could significantly impact telecommunications regulation and the balance of power between federal agencies and the courts. If the Supreme Court affirms the Fifth Circuit's narrow interpretation of FCC authority, it may limit the agency's ability to adapt its regulations to new technologies and market conditions. Conversely, if the Court reverses, it would reaffirm broader FCC authority and potentially signal support for flexible agency regulation in other industries. The decision will affect not only how AT&T, Verizon, and other carriers operate, but also the broader question of how much deference courts should give to agency interpretations of their own statutory powers.

The consolidation of this case with another related case (No. 25-567) suggests that multiple carriers and perhaps other stakeholders challenged overlapping FCC regulations, making this a high-stakes dispute with industry-wide implications.

The FCC possessed statutory authority to issue the challenged regulations, and the Fifth Circuit improperly restricted the agency's delegated power. The Court should reverse and recognize that the FCC's interpretation of its regulatory mandate is entitled to deference as a reasonable exercise of agency discretion.

  • The FCC's statutory authority under telecommunications law encompasses the regulatory power exercised
  • Agency interpretations of ambiguous statutes merit judicial deference under established administrative law principles
  • The Fifth Circuit's decision creates regulatory uncertainty and limits the FCC's ability to govern the telecommunications industry effectively
  • The lower court's narrow reading of FCC authority is inconsistent with the scope of powers delegated by Congress

The FCC regulations at issue exceed the agency's statutory authority and violate the Administrative Procedure Act. The Fifth Circuit correctly identified the limits of the FCC's delegated power, and the Supreme Court should affirm, holding that regulatory authority must remain within the boundaries Congress established.

  • The FCC exceeded its statutory mandate by regulating conduct or entities outside its delegated scope
  • The regulations were arbitrary and capricious or violated procedural requirements under the Administrative Procedure Act
  • Carriers are entitled to clear statutory authorization before bearing compliance burdens imposed by agency regulation
  • The Fifth Circuit's decision properly cabins agency power within constitutionally sound limits on delegation
