HAILEY, Idaho - A pro-marijuana activist who convinced Hailey voters to pass three legalization initiatives in 2007 and 2008 has sued a national organization in 5th District Court, alleging they breached a contract over a $60,000 grant.

Ryan Davidson, chairman of The Liberty Lobby of Idaho, won the grant from Washington D.C.-based Marijuana Policy Project when he moved to central Idaho in 2004 and started his libertarian marijuana movement.

But the group reneged when communities including Sun Valley discarded his ballot petition seeking to legalize marijuana in the resort town. Davidson sued successfully in the Idaho Supreme Court to get his petition on the ballot in Hailey.

He's now seeking $44,000 -- the portion of the Marijuana Policy Project grant he didn't receive -- plus interest.

Davidson says, "They bailed on us and left us hanging."

The group's Bruce Mirken says it has had "difficult interactions" with Davidson.
