Research notes

The Mandate asked for a system with a deadline to update the finding; the administration went further and rescinded it. EO 14154 §6(f) supplied the deadline (30 days), the March 2025 “31 actions” announcement listed the reconsideration, and the final rule closed it.
Litigation (leads — the dockets could not be read without an account; from federal court dockets (CourtListener) as of 2026-06-30): American Public Health Association v. EPA, D.C. Cir. 26-1037, filed 2026-02-18 — https://www.courtlistener.com/docket/72292285/american-public-health-association-v-epa/ ; Zero Emission Transportation Association v. EPA, 26-1039 (2026-02-20) — https://www.courtlistener.com/docket/72312650/zero-emission-transportation-association-inc-v-epa/ ; Commonwealth of Massachusetts v. EPA, 26-1061 (2026-03-19) — https://www.courtlistener.com/docket/72520673/commonwealth-of-massachusetts-v-epa/ . No opinion or stay found.
Same rule carries #1082 (vehicle GHG standards) and is cited by #1158 (social cost of carbon).
2026-10-05: not this item’s rule. State of New York v. EPA (D.C. Cir. 26-1259, filed 2026-10-01) came up in a search for “endangerment finding”. We read the petition (https://storage.courtlistener.com/recap/gov.uscourts.cadc.43642/gov.uscourts.cadc.43642.01208893571.0_1.pdf). It seeks review of Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units, 91 Fed. Reg. 58954 (2026-09-17), and of nothing touching the endangerment rescission. It is recorded at #1053. The litigation list above is unchanged.
