Vice Chancellor Joseph R. Slights III determined last year that Elon Musk and Tesla’s actions in the 2016 acquisition of SolarCity Corp. were imperfect but acceptable, and the Supreme Court of Delaware on Tuesday found the same to be true of Slights’ post-trial opinion.

Justice Karen Valihura wrote in a 106-page opinion that although shareholder appellants had reason to question Slights’ thought process on entire fairness, enough has been presented to show the Chancery decision relied on more than one factor in a vacuum and there’s no need to reverse.
