Washington Supreme Court strikes down voter-approved natural gas initiative
In a 6-3 ruling, justices found Initiative 2066 unconstitutional for combining unrelated subjects, ending a fight over the state's shift away from gas.
What to know
- The Washington Supreme Court ruled 6-3 that voter-approved Initiative 2066 is unconstitutional because it violated the single-subject rule for citizen initiatives.
- I-2066, approved by nearly 52% of voters in 2024, was backed by the Building Industry Association of Washington and aimed to block the state's shift away from natural gas in buildings.
- The ruling affirms a March 2025 King County Superior Court decision and follows a lawsuit from climate groups and local governments filed right after the 2024 election.
- Three justices dissented, with Justice Sal Mungia arguing parts of the initiative could have been severed and upheld rather than voiding it entirely.
