The lawsuit, brought forward by a class of retail Tesla investors including the lead plaintiff, Missouri-based investor Glen Littleton, seeks billions in damages and alleges Musk intentionally moved the company's stock price by providing false or misleading information about the supposed deal to take Tesla private.
