What We Know About Washington's Ruling on Gas Initiative 2066

Opinion. The Washington Supreme Court has struck down Initiative 2066, the ballot measure voters approved in November 2024 to protect residential and commercial access to natural gas, according to The Spokesman-Review. The ruling reinstates state building-code provisions favoring electric heating and appliances over gas hookups — the same rules the initiative was written to block.

What did the Washington Supreme Court decide?

The court's opinion overturns Initiative 2066 outright, rolling back the building-code changes voters put in place at the ballot box, The Spokesman-Review reported. The decision hands a win to the climate-policy advocates who challenged the measure and a setback to the gas utilities and conservative-leaning groups that funded and campaigned for it.

What was Initiative 2066 supposed to guarantee?

Initiative 2066 asked Washington voters to bar state and local agencies from restricting natural gas as an energy option for new construction and to stop the state from pushing utilities toward all-electric building codes. Voters approved it in November 2024. The measure was written specifically to undo building-code changes the state had adopted to encourage electrification — the same changes the court's ruling now revives.

Initiative 2066, by the numbers

• Initiative number: 2066
• Election result: Approved by Washington voters in November 2024
• Court outcome: Struck down by the Washington Supreme Court, reinstating the prior electrification-favoring building codes

Who wins and who loses in the ruling?

Climate advocates and state regulators who favor phasing out gas hookups in new buildings get the outcome they wanted: authority to write building codes that push construction toward electric heating and appliances. Gas utilities and the conservative-leaning groups that backed Initiative 2066 lose a measure they spent money and campaign effort to pass at the ballot box, per The Spokesman-Review's reporting. Neither side's full legal argument is detailed in the available reporting, but the practical result is that a law voters approved directly is now void.

Is this part of a bigger pattern of courts overriding ballot measures?

That is the question critics on the right will ask loudest, and it deserves a straight answer rather than dismissal. Washington's constitution, like every state's, gives courts the power to review whether an initiative conflicts with existing law or with constitutional limits on what voters can enact by ballot measure — a structural feature of federalism, not a partisan invention. HTT's own explainer on how federalism actually works lays out why state supreme courts sit above ballot initiatives in the legal hierarchy, even popular ones.

But there is a fair complaint buried in that structure: when courts strike down initiatives voters passed by direct vote, the gap between what citizens decide and what state law ends up saying grows harder to explain the next time a campaign asks for signatures. That tension — between direct democracy and judicial review — runs through the same debates over voter confidence and election integrity playing out nationally. Washington voters did not get their electricity-or-gas preference wrong on a technicality; they voted, and a court unwound it.

What should Washington residents and builders watch for next?

• Whether gas utilities or Initiative 2066's sponsors seek reconsideration or draft a new ballot measure to replace it.
• Whether the Washington Legislature moves to codify — or further restrict — gas access in statute rather than leaving it to courts and building codes.
• Whether other states with pending gas-access initiatives or electrification mandates cite this ruling in their own legal fights.
• How local building departments apply the reinstated electrification-favoring codes to permits already in the pipeline.

What the ruling doesn't answer yet

The available reporting confirms the outcome — Initiative 2066 is struck down and the prior building-code framework returns — but does not spell out the court's full legal reasoning, the vote count on the bench, or whether an appeal path exists. Readers looking for the underlying legal analysis should go to the source reporting directly, since the opinion itself will carry specifics a news summary cannot.

The larger fact pattern is simple enough: voters approved a gas-access protection at the ballot, and a court has now removed it. Whichever side of the electrification debate a reader sits on, that sequence is the story.
