Elon Musk‘s legal team announced on Thursday that Twitter has rejected their renewed $44 billion offer from the Tesla entrepreneur and that they have requested a Delaware court to halt a forthcoming trial.

To resolve a lengthy legal conflict that started when Musk attempted to back out of the April contract and Twitter sued, Musk reiterated his offer to take over the microblogging site earlier this week.

Requests for comment from Twitter representatives were not immediately answered.

It seems unlikely that the company, whose shareholders have voted in favor of the acquisition, will walk away from the agreement, given that Musk tried to back out of the purchase four months ago and Twitter sued him to force him to complete the deal.

Rather, it’s likely that the San Francisco-based company is seeking assurances from Musk’s side that this time he’s serious and won’t walk away again.

Earlier in the week, Twitter issued a statement saying, “We received the letter from the Musk parties which they have filed with the SEC. The intention of the Company is to close the transaction at $54.20 per share,” thereby confirming their intentions to complete the deal.

Musk has been attempting to back out of the deal for several months after deciding to buy the San Francisco company in April. Shareholders have already approved the sale, and legal experts claimed Musk had a difficult time defending against Twitter’s July complaint.

After Musk said the agreement was off, Twitter filed a lawsuit against him. Musk claimed that Twitter had underestimated the amount of “spam bot” accounts accessing its network.

“Twitter could still be concerned that the same thing might happen again without some additional security,” Robert Anderson, a law professor at Pepperdine University said after Musk renewed his offer. “They’re going to want some assurance that the deal is going to happen right away.”
