The US Supreme Court today rejected Elon Musk's attempt to terminate his settlement with the Securities and Exchange Commission.

Musk appealed to the Supreme Court in December 2023, claiming the settlement he agreed to in 2018 forced him to "waive his First Amendment rights to speak on matters ranging far beyond the charged violations." The SEC settlement requires Musk to get pre-approval from a Tesla securities lawyer for tweets or other social media posts that may contain information material to the company or its shareholders.
