Tesla is now seeking $167 million in a lawsuit against Martin Tripp, the former Tesla employee who CEO Elon Musk has referred to as a saboteur, CNBC first reported. The lawsuit, originally filed in June and seeking just $1 million at the time, alleges Tripp stole confidential and trade secret information, and gave it to third parties.

Tripp, in July, filed a formal whistleblower tip to the U.S. Securities and Exchange Commission alleging Tesla misled investors and put its customers at risk. It’s been a bitter back-and-forth between Tesla and Tripp, who then in August tweeted photos of allegedly damaged batteries at Tesla’s factory.

According to the filing, Tesla has not made Musk available for a deposition. Additionally, the filing argues Tripp’s lawyers need to depose more than 10 people involved with Tesla.

“In this case, where Mr. Tripp is being sued for more than $167,000,000.00 and has asserted counterclaims against Tesla, more than ten (10) depositions is certainly reasonable and appropriate,” Tripp’s lawyers wrote in the filing.

Tesla declined to comment. The case is Tesla, Inc. v Tripp, located in the U.S. District Court for the District of Nevada.
