A federal judge in Honolulu has dismissed a lawsuit filed by the Trump administration that sought to stop the state of Hawaii from suing fossil fuel companies over climate change. The judge ruled that the Justice Department lacked standing to intervene in the state's planned lawsuit, citing a 'longstanding policy' against federal interference in state court proceedings.

Why it matters

This ruling marks the second time in 2026 that federal courts have blocked the Trump administration's efforts to preempt state-level climate change lawsuits against major oil companies. The decision preserves Hawaii's ability to pursue legal action against fossil fuel firms for allegedly contributing to global warming and its impacts on the state.

The details

The Justice Department sued both Hawaii and Michigan in April 2025, seeking to stop them from filing planned lawsuits against major oil companies over climate change. A day after the federal lawsuit was filed, Hawaii sued various fossil fuel companies including BP, Chevron, ExxonMobil and Shell for allegedly selling products the companies knew would warm the planet. U.S. District Judge Helen Gillmor ruled that the Justice Department's case was too speculative and that it lacked standing to intervene in Hawaii's planned state court lawsuit.

  • On April 15, 2026, a federal judge in Honolulu dismissed the Trump administration's lawsuit seeking to block Hawaii's climate change lawsuit against fossil fuel companies.
  • In January 2026, a different federal judge threw out a similar Justice Department lawsuit that aimed to stop the state of Michigan from suing major oil companies over climate change.

What they’re saying

“The Justice Department's 'attempt to predict the outcome of a yet-to-be-filed lawsuit and how it could possibly injure the federal government in the future is not a concrete injury-in-fact.'”

— U.S. District Judge Helen Gillmor

What’s next

The dismissal of the Trump administration's lawsuit clears the way for Hawaii to proceed with its planned lawsuit against fossil fuel companies over climate change impacts. The state is expected to file the lawsuit in the coming months.

The takeaway

This ruling represents a significant victory for states' rights and the ability of state governments to hold fossil fuel companies accountable for their role in driving climate change. It also highlights the ongoing legal battles between states and the federal government over climate policy and regulation.
