On Friday Elon Musk filed a motion opposing Twitter’s request to fast-track the trial over his pulling out of a $44 billion deal to buy the social media firm.

Musk’s lawyers called it an “unjustifiable request” in court papers, and demanded it be rejected.

It is the latest clash in the battle between the social media company and the tech billionaire.

In the suit filed by Twitter, seeking to force Musk to complete his purchase of the company at the agreed upon $54.20 per share price, Twitter requested the trial begin in September, due to the merger agreement with Musk terminating on October 25th.

Musk’s lawyers wrote in response, “Twitter’s sudden request for warp speed after two months of foot-dragging and obfuscation is its latest tactic to shroud the truth about spam accounts long enough to railroad defendants into closing.”

Musk’s lawyers argued the fundamental issue in the case is the number of twitter users which are bot and spam accounts, and that the issue is very data and expert-intensive. They argued this would require substantial time for discovery and analysis, and requested a trial date on or after February 13th of 2023.

Musk’s debt-financing deal committed to by banks expires in April of 2023, so if the trial were to not finish by that date, the entire deal could collapse due to a lack of funding.

Twitter declined to comment on Musk’s motion. Shares were down about 1% in extended trading.
