evidence: Musk heads to Delaware’s Court of Chancery on July 12 to defend the deal. He’s the sole remaining defendant in a case brought by shareholders alleging that the SolarCity purchase was a bailout of a troubled company founded by his cousins in which he was the biggest investor and chairman. The suit had also accused Tesla’s board of lax corporate governance. Board members, led by chair Robyn Denholm, settled for $60 million last year, admitting no fault. But Musk opted to defend the purchase. A loss in the case could cost him more than $2 billion, the full cost of the acquisition, which would be one of the largest judgments ever against an individual corporate executive. While companies such as Bank of America and BP have faced damage awards in the billions for their roles in events such as the mortgage-backed security collapse and disastrous Deepwater Horizon oil spill, individual executives are seldom solely liable for such large amounts.
