Elon Musk's Twitter use restricted after court ruling.
Elon Musk has lost his appeal against a ruling that requires a lawyer's approval for some Tesla-related tweets. The federal appeals court in Manhattan has rejected Musk's claim that the 2018 consent decree with the SEC is an unfair "prior restraint" on his speech. The CEO could have defended himself against the charges or negotiated a different deal if he'd wanted to tweet without a legal monitor, the court panel says.
