Musk, Twitter Trade Barbs at Wide-Ranging Hearing

Lawyers for Elon Musk and Twitter ended a wide-ranging hearing over their stalled $44 billion deal debating the issue that may further complicate and extend their legal fight: whether Mr. Musk can incorporate a whistleblower’s allegations into his countersuit.

Chancellor Kathaleen McCormick didn’t rule on that or any of the other questions raised during the roughly three-and-a-half-hour oral arguments Tuesday, which included the pace and substance of the discovery process, Mr. Musk’s motivations for seeking to exit from the deal and the timing of the trial, among other factors. She concluded the hearing only by saying both parties earned a good night’s rest.
