The complaint includes allegations of fraud, breach of contract and trademark violations against 10 defendants and will be scheduled for hearing in an Oakland, Calif., district court.

Cadogan charges that 3EB lead singer Stephan Jenkins, the band and other co-defendants “lied and intentionally deceived him in a carefully orchestrated plot to unlawfully exploit his intellectual property in violation of federal and common law.” The filing was announced in a press release posted June 16 at Cadogan’s Web site.

Other defendants include band manager Eric Godtland, lawyer Tim Mandelbaum and Elektra Entertainment Group.

Eric Godtland Management told Pollstar that “bands with any degree of visibility are always targets of frivolous lawsuits. We have nothing interesting to say about this one.” Russell Bloom, a spokesman for EGM, told Pollstar that the firm has received a copy of the complaint but would have no further comment.

The feud between Cadogan and his former bandmates provided some drama at April’s California Music Awards – formerly known as the Bammies – where Cadogan and Jenkins shared outstanding songwriter accolades for their Third Eye Blind work.

Since Jenkins and the band were on the road, they were faced with the prospect of the ousted Cadogan accepting the award for them. There reportedly were some tense moments when Godtland instead took the podium and accepted the award with Cadogan, and the two exchanged some verbal jabs.
