Washington Governor Jay Inslee calls climate change an "existential threat," and he has channeled President Obama in using executive powers to impose his policy response. But like Mr. Obama he suffered a major blow this month when a Washington court ruled that he exceeded his authority under state law.
Washington lawmakers have declined to pass Mr. Inslee's signature cap-and-trade legislation, and in 2016 voters rejected a carbon-tax ballot measure. So "now we have to do it administratively," the Sierra Club's Doug Howell said last year.
Mr. Inslee suddenly discovered authority to act unilaterally under the Washington Clean Air Act and a 2008 law that required greenhouse gas reductions...
And in a Dec. 15 oral ruling, Thurston County Superior Court Judge James Dixon found that the Inslee Administration lacked the legal authority to regulate indirect emitters.
The decision is a victory for the rule of law and another rebuke to progressives who try to ignore democratic consent to impose their climate agenda by regulatory fiat.
