Tesla has lost another driver. Alan Prescott, vice president of legal and acting general counsel of the electric car company, has driven off to join Luminar Technologies Inc. Prescott had replaced general counsel Todd Maron, chief executive officer Elon Musk’s former divorce lawyer who joined Tesla in 2014. Maron left the company in March.

This is the fourth departure from Tesla’s general counsel seat in a little under two years. (Prescott’s predecessors were Jonathan Chang, who left in December 2019 after about a year; Maron, who left in December 2018; and Dane Butswinkas, who left after two months.) Palo Alto-based Tesla is also facing a lawsuit in Delaware Chancery Court over the executive turmoil. The investor-filed suit against the board alleges, among other things, that “the Board has also consistently failed to ensure that Tesla has an independent General Counsel who can provide advice untainted by Musk.”
