The only thing surprising about Martin Eberhard's latest move is that it took so long to happen. Eberhard was co-founder of Tesla Motors along with Mark Tarpenning, and he was ousted from the company in November 2007 by then-chairman Elon Musk. Musk has never been one to hide his feelings about other people (or much of anything) – and comments he has made about Eberhard and his role in the company have clearly not gone over well.
To nobody's surprise, Eberhard has filed a lawsuit in California Superior Court in San Mateo against Musk and Tesla Motors. In the suit, Eberhard accuses Musk of slander and libel, along with breaching the contracts that he and the company had with Eberhard. At 146 pages, we haven't yet had time to digest the entire complaint (though we do find it interesting that our coverage is mentioned in the lawsuit), but we have a sneaking suspicion this one is going to get ugly...
