In a decisive 7–2 ruling, the U.S. Supreme Court dealt a significant setback to California’s climate agenda, rejecting key components of Governor Gavin Newsom’s environmental platform.
Justice Brett Kavanaugh, writing for the majority, determined that the state’s electric vehicle mandates and ambitious emissions targets may conflict with federal law, potentially allowing energy producers to contest the Environmental Protection Agency’s endorsement of those policies. "The government may not strangle an industry through unlawful regulation and then hide behind immunity,” Kavanaugh wrote, criticizing the EPA for inconsistent legal positions over time.
The decision represents a major win for American fuel manufacturers and undercuts Newsom’s high-profile plan to phase out new gas-powered car sales by 2035. It follows recent actions by former President Donald Trump to roll back multiple California environmental rules, underscoring a broader shift in the national debate over energy policy.
In a related 6–3 ruling, the Court also reinforced federal immigration authority by restoring the government’s ability to conduct large-scale enforcement operations. Together, the two decisions signal the Court’s firm stance against what it views as state overreach and judicial oversteps.
