A Delaware court denied Elon Musk’s request to delay the trial over his attempt to abandon a $44 billion deal to buy Twitter, according to a new filing released on Wednesday.

But the billionaire Tesla CEO will be allowed to add claims from a Twitter whistleblower to his countersuit, Chancellor Kathaleen McCormick ruled.

The trial is expected to begin on October 17, earlier than the mid-November date Musk’s team requested in its latest push.

“I previously rejected Defendants’ arguments in response to Twitter’s motion to expedite, making clear that the longer the delay until trial, the greater the risk of irreparable harm to Twitter,” McCormick wrote. “I am convinced that even four weeks’ delay would risk further harm to Twitter too great to justify.”
