Client Alert: The US Supreme Court is Asked to Stop Compliance with California Climate Laws

Chambers Seek Emergency Injunction to Halt SB 261 and SB 253 Enforcement

On November 10, the US Chamber of Commerce and several state Chambers filed an emergency application with the US Supreme Court for an injunction. The Chambers, whose lawsuit against the State of California regarding SB 261 and SB 253 is pending in the Ninth Circuit, have asked the US Supreme Court to prohibit the State of California from enforcing SB 261 and SB 253 during the litigation in lower courts. 

The Supreme Court has not yet responded on whether it will accept the case. 

The first deadline the plaintiffs are asking to be stopped is the January 1, 2026, deadline for companies covered under the SB 261 law. This is the deadline for in-scope companies to publish and submit their report required by SB 261.

Given this uncertainty, companies should continue preparing to meet SB 261’s current reporting deadline and not rely on a potential delay.
