Judge Rejects Trump DOJ Bid to Block Michigan’s Climate Lawsuit Against Oil Giants

A federal judge has dismissed an effort by the Trump administration to stop Michigan from pursuing legal action against major oil companies over their role in climate change, dealing a setback to the administration’s broader push to shield the fossil fuel industry from state-led litigation.

U.S. District Judge Jane Beckering ruled that the Justice Department’s lawsuit was “too speculative,” saying it relied on hypothetical claims Michigan might bring at some undefined point in the future. The ruling came just one day after Michigan Attorney General Dana Nessel filed a separate federal antitrust lawsuit accusing leading fossil fuel companies of colluding to suppress competition from renewable energy and misleading the public about climate risks.

While Judge Beckering did not directly address Michigan’s newly filed antitrust case, she made clear that the federal government could not preemptively block a state from pursuing potential claims. She noted that the DOJ’s arguments were even more attenuated than a similar case the U.S. Supreme Court declined to hear last year, when Republican-led states sought to halt climate lawsuits by Democratic-led states.

The Justice Department had sued Michigan in April under President Donald Trump’s executive order titled “Protecting American Energy from State Overreach,” which directed federal agencies to counter state laws and lawsuits seen as burdening domestic energy production. DOJ officials argued that any state-level climate case would unlawfully interfere with federal authority over greenhouse gas regulation and foreign policy.

Nessel’s office has said Michigan’s legal actions stem from investigations into what it describes as decades of deception by the fossil fuel industry regarding climate change. Oil majors including Exxon Mobil, Chevron, BP and Shell have consistently denied wrongdoing.

The ruling allows Michigan to continue exploring climate-related litigation, reinforcing the ability of states to challenge fossil fuel companies despite federal opposition.
