Decision
Emergency motion granted in part.
In an appeal from a district court order denying a preliminary injunction enjoining two California laws requiring climate change-related disclosures by certain large companies, the Ninth Circuit Court of Appeals denied the portion of the appellants’ emergency motion requesting that the Ninth Circuit merits panel rule by November 3, 2025 on their pending motion for injunction pending appeal. The Ninth Circuit directed that the case immediately be assigned to a merits panel and placed the case, which has been fully briefed as of November 6, on the calendar for January 2026. The appellants’ motion argued that they faced “imminent and irreparable First Amendment harm because California Senate Bills 253 and 261 require covered companies to publish State-mandated reports as soon as January 1, 2026, compelling them to speak the State’s preferred views on climate change, and Plaintiffs’ members are currently incurring unrecoverable compliance costs.” They told the Ninth Circuit that a ruling by November 3 would permit “orderly Supreme Court review if necessary.”
