The D.C. Circuit Court of Appeals agrees to review the rollback of carbon pollution standards for fossil-fuel power plants.

  The D.C. Circuit has already docketed this case; the question is whether it formally grants review, which is near-certain given standing petitions.

  • The D.C. Circuit has a statutory obligation under the Clean Air Act to hear challenges to EPA rules; 26 states petitioned, so jurisdiction is clear.
  • Historically, the D.C. Circuit grants review of EPA rule challenges at rates above 95% when petitioners have standing, which state AGs always do.
  • A docket entry setting briefing schedule or oral argument would resolve this; the court typically does so within months of petition filing, well before Oct 2027.

  The D.C. Circuit almost certainly will docket and schedule merits review of a timely Clean Air Act challenge within a year.

  • Petitions already filed by 26 governments give the court a live administrative-law case; the clerk and panel control the next steps.
  • D.C. Circuit review of nationally applicable EPA rules is the ordinary statutory path, and merits scheduling commonly follows briefing in months.
  • This would fall mainly if EPA withdraws, replaces, or stays the rollback before briefing, mooting the petitions.

  The Clean Air Act grants direct review of EPA standards to the D.C. Circuit, making formal review virtually automatic.

  • Under 42 U.S.C. 7607(b), the D.C. Circuit has mandatory original jurisdiction over EPA national rulemaking challenges.
  • A formal briefing or oral argument schedule docket entry is virtually guaranteed well before October 2027.
  • Only a wholesale standing dismissal or an early voluntary remand without scheduling would prevent this from triggering.

  CAA petitions for review of EPA power-plant rules are docketed as of right in D.C. Circuit.

  • States already filed; Clean Air Act §307(b) gives the court mandatory jurisdiction once a final rule issues.
  • Briefing or argument schedules are routinely set within months of a timely petition, well inside the one-year window.
  • Only a withdrawal of the rule or a jurisdictional dismissal would stop review; neither is the base-rate outcome for these challenges.

  The D.C. Circuit almost never refuses a properly filed petition for review of a final EPA rule.

  • Twenty-six states and cities filed a timely petition for review of a final rule, and the D.C. Circuit's jurisdiction is mandatory, not discretionary.
  • The court has already docketed the case; the only question is whether it issues a scheduling order or consolidates before October 2027.
  • Base rate: the D.C. Circuit grants review in essentially every final EPA rule challenge; it has no certiorari-style discretion here.

  Hinges on whether the EPA finalizes repeal and petitioners get standing before the D.C. Circuit's typical docketing timeline.

  • Courts of appeals routinely grant review/docket petitions challenging final EPA rules, so procedural acceptance is near-automatic once a final rule issues.
  • 26 states/cities already filed petitions, showing active litigants ready to push the case through standard briefing schedules within a year.
  • Main risk is delay if EPA's final rule is still pending or gets withdrawn/revised, which would push docketing past Oct 2027.
