The Washington State Supreme Court gave the green light for Friday's transition to private liquor sales by rejecting a lawsuit Thursday that claimed I-1183 violated the state's constitution .

Opponents had claimed the initiative violated state law because it contained a provision to set aside funding for public safety. Michael Subit, the attorney who represented those who filed the lawsuit, told The Seattle Times the ruling effectively marks the end of opponents' efforts against the new law.

"There's nowhere to go from here. On the issue of the constitutionality of a state statute, the Washington Supreme Court is the final word," Subit told the newspaper.
