Elon Musk's lawyers said that Twitter is refusing to accept the Tesla billionaire's renewed $44 billion bid for the social media company and are asking a Delaware court to halt an upcoming trial.

Musk made a renewed offer to take over the social media platform earlier this week, hoping to end a protracted legal dispute that began when Musk tried to back out of the April deal and Twitter sued.

Representatives for Twitter did not immediately respond to messages for comment.

Twitter said earlier this week that it intends to close the deal at the agreed-upon price, but the two sides are still booked for an October 17 trial in Delaware over Musk's earlier attempts to terminate the deal. On Wednesday, the judge presiding over the case said she will continue to press on toward the trial because, at the time, neither side had formally moved to stop it.

Musk's attorneys said the trial should be adjourned to leave more time for Musk to secure the financing.

"Twitter will not take yes for an answer," said the court filing signed by Musk attorney Edward Micheletti. "Astonishingly, they have insisted on proceeding with this litigation, recklessly putting the deal at risk and gambling with their stockholders' interests."

Since Twitter sued Musk to force him to complete the purchase after he tried to back out four months ago, it is unlikely the San Francisco-based company — whose shareholders have voted to approve the deal — will walk away from the agreement.

Rather, it's likely Twitter is seeking assurances from Musk's side that this time he's serious and won't walk away again.

Eric Talley, a Columbia University law professor, tweeted that Twitter "is absolutely right not to take 'yes' for an answer, and everyone knows why. (They tried that in April and it didn't go so well)." He added that Twitter would, however, take a "certified bank transfer" from Musk.

Musk attorneys said Musk's financial backers "have indicated that they are prepared to honour their commitments" and are working to close the deal by October 28, roughly a week after the trial was set to conclude.
