H. Peter Haveles, Jr., a partner in the Trial and Dispute Resolution Practice Group of Pepper Hamilton, was quoted in the March 7, 2019 The Verge article, "Can a Judge Order Elon Musk to Delete His Twitter Account?"
The nuclear option is to bar Musk from serving as an officer or director of a publicly traded company, but Peter Haveles, a partner at Pepper Hamilton in New York whose practice deals with commercial and regulatory disputes, told me that seems unlikely. A fine is likelier. But since Musk is a billionaire, a fine might be something he shrugs off. Which is how I began wondering if a judge can force Musk to delete his Twitter account, since it seems to be where the contentious information is coming from. Also, Musk seems to genuinely enjoy Twitter, so barring him is a fairly effective punishment.
