Senators on Monday voted 21-13 to defeat the law enforcement resolution amid concerns it contradicts previous measures to ensure Idaho's sovereignty.
Boise Republican Sen. Chuck Winder argued that both measures were intended to show Idaho doesn't plan to go the path of some surrounding states like Washington, where voters last fall legalized pot.
Nampa Republican Sen. Curt McKenzie said the enforcement proposal contradicts the idea of states' rights a principle his party used to oppose federal health care and endangered species laws. McKenzie doubted how the resolutions would make Idaho safer.
The Senate endorsed the anti-marijuana measure 29-5.
