City of Arlington v. Fed. Commc'ns Comm'n
The Supreme Court ruled that courts must use the same deferential Chevron standard when reviewing an agency's interpretation of the scope of its own regulatory authority as they use for any other agency interpretation of an ambiguous statute.
The decision rejected the idea that there is a special category of 'jurisdictional' questions where courts should decide for themselves without deferring to the agency, a distinction the Court called illusory. This preserves broad room for federal agencies like the FCC to define the boundaries of their own power when Congress has left a gap.
How it got here: The cities challenged the FCC's ruling in the Fifth Circuit, which deferred to the FCC and upheld the deadlines; the cities asked the Supreme Court to review that deference decision.
The Case in Depth
What happened
Wireless companies faced long delays getting local zoning approval for cell towers and antennas. Responding to an industry petition, the Federal Communications Commission issued a ruling saying local governments must act on siting applications within 90 days for antennas on existing towers and 150 days for other requests. The cities of Arlington and San Antonio, Texas, and a New Orleans city council committee argued the FCC had no authority to interpret the relevant statute at all.
The question before the Court
When a federal agency's own reading of a law decides how far its regulatory power reaches, must courts defer to that reading the same way they defer on other legal questions?
Why it matters
Federal agencies interpreting ambiguous statutes will keep getting deference from courts even when the dispute is really about how far their own power extends, not just how they use it. This matters for cities, companies, and anyone affected by agency rules on telecommunications, environmental permitting, labor law, and beyond, because it keeps more line-drawing power with agencies rather than judges.
What changes now
The Fifth Circuit's decision upholding the FCC's 90- and 150-day timelines for local governments to act on wireless-siting applications stands. This is a final merits ruling that resolves the legal question of how courts review agency interpretations of the scope of their own authority; going forward, courts applying Chevron will not treat 'jurisdictional' agency interpretations differently from other interpretations of ambiguous statutes.
What this does not decide
The Court did not decide whether every specific agency interpretation is entitled to deference regardless of context — Justice Breyer's concurrence stressed that courts must still independently determine whether Congress actually delegated interpretive authority in the particular manner the agency used, a step the majority also required but treated as satisfied here.
Concurrences and dissents
Concurrence — Justice Breyer
Justice Breyer agreed that there is no separate category of jurisdictional questions exempt from deference, but stressed that deciding whether Congress actually left a gap for an agency to fill is not always simple. He listed several context-specific factors courts should weigh, such as the agency's expertise, the interstitial nature of the question, and the complexity of the statutory scheme, and applied those factors to conclude the FCC deserved deference here.
Dissent — Justice Roberts
“A court should not defer to an agency until the court decides, on its own, that the agency is entitled to deference.”The dissent's central objection that courts must independently confirm an agency's delegated authority before deferring.
Chief Justice Roberts argued that a court must first decide for itself, without deferring to the agency, whether Congress actually delegated interpretive authority over the specific ambiguous provision at issue before applying Chevron deference at all. He contended that treating a general grant of rulemaking authority as automatically covering every ambiguity within the broader statute skips this necessary threshold inquiry and risks letting agencies expand their own power unchecked. He would have vacated and remanded for the Fifth Circuit to decide that threshold delegation question itself.
How the Court got there
The legal reasoning, step by step
- The Court applied the two-step Chevron framework, which asks first whether Congress has directly addressed the issue and, if not, whether the agency's reading of the ambiguous statute is a reasonable one deserving deference.
- The Court rejected the idea that a special subset of 'jurisdictional' questions — those about the outer boundary of an agency's power — should be reviewed without any deference, reasoning that any agency overreach, whether framed as exceeding its jurisdiction or misapplying authority it clearly has, is simply an instance of exceeding what Congress permitted.
- The Court explained that the jurisdictional/non-jurisdictional line makes sense for courts, whose power to decide a case is separate from whether they decide it correctly, but does not carry over to agencies, whose power to act and how they act are both defined by the same congressional statute.
- Applying that reasoning, the Court found no principled way to distinguish 'big' interpretive questions from 'humdrum' ones, since virtually any agency action can be described either way depending on how broadly one frames the underlying statutory authority.
- The Court concluded that because Congress had unambiguously given the FCC general authority to administer the Communications Act through rulemaking and adjudication, and the disputed timing rule was issued through that rulemaking process, the preconditions for Chevron deference were satisfied.
