A lawsuit is going to trial in U.S. District Court over a tweet from Mr. Musk about taking Tesla private.
The Securities and Exchange Commission had filed a separate lawsuit over the plan, which was settled with fines to the S.E.C. and Mr. Musk stepping down as chairman of Tesla.
Mr. Musk has always struggled to show that he had the funding to take Tesla private, he may seek to introduce new evidence and testimony in court that backs him up.
His legal team subpoenaed employees of the Saudi fund, but later withdrew the subpoenas after they were deemed “legally deficient” and “frankly, frivolous.”
