Beats wins in case alleging double-crossing of ex-partner

judge has dismissed the key claims in a lawsuit alleging that headphone maker Beats Electronics duped one of its early partners before negotiating its $3-billion sale to Apple Inc. two years ago.

The summary judgment issued late Monday by Los Angeles County Superior Court Judge William Fahey resolves the heart of a case that accused Beats coship founders Dr. Dre and Jimmy Iovine of double-crossing former partner Noel Lee, founder of video and audio cable maker Monster.

The allegations, made in a lawsuit filed last year, had been scheduled to go to trial next week. Now the trial will be limited to Beats’ effort to force Monster to pay its attorney fees and other costs.

Monster attorney Philip Gregory did not respond to requests for comment.

Lee once held a 5% stake in Beats as part of a partnerA between the headphone maker and Monster that ended in 2012. The lawsuit alleged Dre, a former rap singer whose real name is Andre Young, and Iovine, a former record producer, orchestrated a “sham” deal with smartphone maker HTC in 2011 that led to the termination of the Monster alliance.

But Fahey concluded that Beats’ actions were allowed under the contracts that Lee and Monster had entered into as sophisticated investors.

The lawsuit alleged Beats’ misrepresentations had caused Lee to sell his remaining 1.25% stake for $5.5 million in 2013. That would have been worth more than $30 million had he owned it at the time of Beats’ sale to Apple. Lee’s original stake would have landed him roughly $150 million.

Fahey also dismissed Monster’s claims alleging misconduct by HTC America and Paul Wachter, a Beats investor and board member.
