Unreported / Non-Citable
Background
Central Valley Air Quality Coalition and several related organizations sued the San Joaquin Valley Unified Air Pollution Control District and its Governing Board under the Clean Air Act's citizen-suit provision, 42 U.S.C. § 7604(a)(1), alleging violations of a state implementation plan. The Air District moved to dismiss, arguing the statute does not authorize citizen suits against it in its regulatory capacity. The district court denied that motion, concluding that two Ninth Circuit decisions—Committee for a Better Arvin v. United States EPA and Ass'n of Irritated Residents v. United States EPA—necessarily determined that § 7604(a)(1) permits suits against regulators, and that this determination was a necessary component of those decisions rather than dicta.
Following that ruling, the Air District asked the court under 28 U.S.C. § 1292(b) to certify for interlocutory appeal whether Section 304(a)(1) of the Clean Air Act authorizes a citizen suit against a state or local air pollution control agency acting as a regulator, and to stay all proceedings pending any petition and appeal. Central Valley opposed certification but said it would not oppose a stay if certification were granted.
The Court’s Holding
The court denied the motion. Section 1292(b) permits interlocutory appeal only when an order involves a controlling question of law, there is substantial ground for difference of opinion, and immediate appeal may materially advance the litigation—and even then certification is discretionary. Because the court had already found that Arvin and AIR are controlling Ninth Circuit precedent resolving the exact question the Air District sought to certify, there was no substantial ground for difference of opinion. The court rejected the argument that City & County of San Francisco v. United States Department of Transportation created an intra-circuit split: AIR was decided six years later without noting any tension, and San Francisco addressed the Pipeline Safety Act, not the Clean Air Act, so the cases were not irreconcilable.
The court also rejected the contention that reasonable judges could disagree whether Arvin and AIR were holdings or dicta, reasoning that distinguishing binding precedent from dictum is routine for lower courts, that any error can be corrected on direct appeal from a final judgment, and that such an expansive argument would invite interlocutory appeals in numerous cases and undermine § 1292(b)'s role as a narrow exception to the final-judgment rule. Nor had the Air District shown exceptional circumstances; its discovery-cost concerns could be managed through ordinary tools. Because certification was unwarranted, the court denied the stay, which would prejudice Central Valley by delaying resolution.
Key Takeaways
- A district court may deny § 1292(b) certification when controlling circuit precedent already answers the question the movant seeks to appeal, even if the movant believes that precedent is wrong.
- A substantial ground for difference of opinion requires more than a party's disagreement with how the court interpreted binding appellate decisions.
- An argument that the line between holding and dicta is generally uncertain is too expansive to justify interlocutory appeal because it would apply in numerous cases and erode the final-judgment rule.
- Potential discovery costs, without a showing that they are especially burdensome, do not constitute the exceptional circumstances required for interlocutory review under § 1292(b).
- When certification of an interlocutory appeal is denied, a stay premised solely on that certification will also be denied, particularly where delay would prejudice the opposing party.
Why It Matters
This order reinforces the stringent standards governing interlocutory appeals under 28 U.S.C. § 1292(b) and underscores that the provision is reserved for exceptional situations, not merely difficult or important rulings. It illustrates that a district court's confidence in controlling precedent—here, Ninth Circuit decisions recognizing Clean Air Act citizen suits against regulators—can foreclose certification even when the losing party genuinely believes the issue warrants immediate appellate attention.
For Clean Air Act litigation in the Ninth Circuit, the order signals continued judicial willingness to allow citizen suits against regulatory agencies to proceed rather than being delayed by interlocutory challenges to the settled understanding of § 7604(a)(1).
