Delaware Vice Chancellor Joseph Slights wasn’t exactly glowing last month in his assessment of the process by which Elon Musk’s Tesla came to purchase SolarCity, a company founded by his cousins where he served as the chairman and largest shareholder.  

In fact, “far from perfect” were the vice chancellor’s words in a 131-page decision weighing shareholder derivate claims against Musk. “Elon was more involved in the process than a conflicted fiduciary should be. And conflicts among other Tesla Board members were not completely neutralized,” Slights wrote.
