At issue was a 2016 acquisition of Solar City Corp. by Tesla. Some Tesla shareholders claimed that Musk caused Tesla to overpay for Solar through his alleged domination and control of Tesla’s board. The primary focus of the shareholders was that Solar was insolvent at the time of the acquisition. The court applied the “entire fairness” standard. The Court of Chancery found the acquisition to be “entirely fair.” The Delaware Supreme Court affirmed the Court of Chancery decision.
