Elon Musk filed a motion on Friday opposing Twitter Inc's TWTR.N request to fast-track a trial over his plan to terminate his $44 billion deal for the social media firm.
Musk's lawyers, in papers filed with the Delaware Chancery Court, said Twitter's "unjustifiable request to rush this $44 billion merger case to trial in just two months" should be rejected.
The lawyers have requested for a trial date on or after Feb. 13 next year.
Twitter did not immediately respond to a request for comment.
Shares of Twitter were down about 1% in extended trading.
