No breakup is easy. The spit between Stone Temple Pilots and former frontman Scott Weiland is proving it, even three months later as it escalates into legal actions.

According to Billboard, Weiland found out of his ousting from STP in February through a statement released to the media, yet still refuses to acknowledge it. The newly reconfigured STP has now taken out a lawsuit in order to enforce the changes.

Last week STP played at L.A. radio station KROQ’s Weenie Roast with Chester Bennington from Linkin Park. It was confirmed after the performance that Bennington is selected as the new full-time vocalist for the band.

Weiland responded on Friday through his Facebook page with an open letter to fans. He announced his disapproval of the move. “The band that played last weekend was not Stone Temple Pilots and it was wrong of them to present themselves as that.”

“First of all they don’t have the legal right to call themselves STP because I’m still a member of the band. And more importantly, they don’t have the ethical right to call themselves Stone Temple Pilots because it’s misleading and dishonest to the millions of fans that have followed us for so many years.”

STP took out the lawsuit the same day in L.A. It sheds light on reasons behind the February breakup as well as their current struggles dealing with the now 45-year old ex-frontman.

“The band endured much strife and lost significant opportunities because of Weiland,” the lawsuit states. It cites occurrences of Weiland being habitually late to 2012 concerts as well as interacting with bandmates solely through lawyers and managers.

More recently Weiland was interfering with airtime of STP’s recent single “Out of Time”.  Apparently his lawyer called the L.A. rock station KROQ and alleged that playing the song would infringe on the singer’s rights.

Citing two agreements, one from 1996 and another in 2010, that state no former member of STP can use the name, copyrights, or trademarks of the band, the lawsuit accuses Weiland of using the Stone Temple Pilots name to further his own solo career. He denied the accusation in the letter on Friday.

STP is intent on making a clean break from Weiland. “Enough is enough,” reads the lawsuit “without relief from the court, Weiland will continue violating STP’s rights, misappropriating STP assets and interfering with the bands livelihood.”

Scott Wieland’s Letter to fans:

A letter to my fans,

Like everybody else out there, I read about my band, Stone Temple Pilots, and their recent performance this past weekend with a new singer. To tell you the truth, it took me by surprise. And it hurt.

But the band that played last weekend was not Stone Temple Pilots and it was wrong of them to present themselves as that.

First of all they don’t have the legal right to call themselves STP because I’m still a member of the band. And more importantly, they don’t have the ethical right to call themselves Stone Temple Pilots because it’s misleading and dishonest to the millions of fans that have followed us for so many years.

When I tour on my own, it’s never as Stone Temple Pilots. It’s as Scott Weiland. The fans deserve to know what they’re getting.

Like any band that’s stood the test of time and made music for more than two decades, STP had a special alchemy – the four of us together were greater than any one of us apart. So if my former bandmates want to tour with a new singer, that’s their prerogative.

I don’t give a fuck what they call themselves, but it’s not Stone Temple Pilots.
And so I say to you, our fans, I’ll see you out there on the road this summer where I’m touring as “Scott Weiland” with my band The Wildabouts. But don’t give up on STP. I know I haven’t.
