From the American Spectator:

Today the Evergreen Freedom Foundation’s Constitutional Law Center announced they would, on behalf of Washington State taxpayers, sue Democrat Gov. Christine Gregoire because last year she issued an executive order implementing climate change measures that the Democrat-run state legislature had rejected.
“We believe Gov. Gregoire’s climate change executive order is an unconstitutional order,” said Michael Reitz, director of the Evergreen Freedom Foundation’s Constitutional Law Center, who represents the taxpayers in this case. “Gov. Gregoire violated the doctrine of separation of powers by snatching a failed bill out of the legislative process and issuing it in the form of an executive order. If the governor wants to pass laws, she’s in the wrong branch of government.”
Indeed, Gregoire is such an Unconstitutionalist (as a former attorney general, she should know better) that she admitted openly last year she wanted to circumvent Washingtonians’ elected representatives, telling the Los Angeles Times, “I wanted cap-and-trade. I didn’t get it.”
