Elon Musk countersued Twitter on Friday just minutes before the 5 p.m. judge-imposed deadline — intensifying the conflict between the Tesla CEO and the social networking company he agreed to buy

The entrepreneur’s 164-page document was not publicly available, however, under court rules a redacted version could soon be published, according to The Guardian.

It wasn’t clear why Musk asked the court to keep details of his countersuit confidential when the South African billionaire, who is also the CEO of SpaceX, had been vocally critical of Twitter on social media and in press interviews in recent months.

Soon after they signed the deal, Musk accused Twitter of lying about the number of spam and bot accounts on its platform and denying him access to information about their handling of these accounts. Musk formally said he wanted to terminate the deal earlier this month, and Twitter sued him in the Delaware Court of Chancery to force him to go through with the deal.

A judge in Delaware, where Twitter is incorporated, has since ordered a five-day trial on the matter to commence on Oct. 17. Twitter, which has urged its shareholders to support Musk’s buyout offer, will vote on the merger on Sept. 13, the Huffpost reported.

The Huffpost went on to report that “Musk was given at least 49 tebibytes of internal data serving as a real-time record of more than 500 million daily tweets since June 19. Musk also said he might launch a competing service if the buyout failed.”

“This is one of the biggest worries that target companies have: That a buyer walks away with detailed knowledge of their ‘secret sauce’ and then uses it to compete with or otherwise undermine them,” Columbia Law School professor Eric Talley told HuffPost.
