An attorney for Musk, who is also the CEO of electric car maker Tesla Inc, did not respond to a request for comment.
“We are pleased that the court agreed to expedite this trial,” a Twitter spokesperson said.
Twitter wants McCormick to order Musk to complete the deal at the agreed price of $54.20 per share. It said it needed the earliest possible trial date in case Musk was ordered to close and additional litigation was then needed to address financing, which expires in April.
Twitter’s lawyer William Savitt argued during the hearing that Musk seized on the issue of bot and spam accounts because he was seeking to “conjure an exit ramp for a deal that doesn’t have one.”
Musk's attorney pushed back on the notion that Musk was trying to harm Twitter, pointing out the billionaire held a larger stake than the combined holdings of the directors of Twitter.
Musk had argued an expedited trial would allow Twitter to hide the truth about spam accounts, which Musk began questioning after signing the deal for Twitter in late April.
“When Mr. Musk started asking questions, the answers he got were alarming,” said Andrew Rossman, Musk's lawyer. He said it will take months to analyse massive amounts of data to resolve Musk's questions about Twitter's spam accounts.
Musk is already facing a separate five-day trial before McCormick, starting on October 24, over his record $56bn pay package from Tesla.
