"How do you expel a man from a band that he started, named, sang lead on every song, wrote the lyrics and was the face of for 20 years, and then try to grab the name and goodwill for yourselves?" Weiland's complaint reads. "You don't, but three of the instrumentalists from the band 'Stone Temple Pilots' (the 'Band') tried."

According to Weiland's 74-page filing, a partnership agreement signed by STONE TEMPLE PILOTS in 1996, and amended in 2010, allows each bandmember to perform on his own. Under the agreement, STONE TEMPLE PILOTS members Robert DeLeo (bass), Dean DeLeo (guitar) and Eric Kretz (drums) would be forced to play under a different name if separate and apart from Scott.

STONE TEMPLE PILOTS issued a statement late last week explaining why they launched legal action against Weiland. After firing him earlier this year, the band filed a lawsuit claiming that Weiland's erratic performances, late arrivals for shows and struggles with addiction had harmed their career. The group said in the statement, "Our purpose in taking this action is not to hurt Scott. We want to move forward productively, and Scott's choices and actions have prevented us from doing that . . . It was beyond time we made some new music, which was impossible in the dysfunctional environment we were in. We've lived in it long enough and have decided to move forward with STP. We wish Scott well."
