Elon Musk has been issued a court summons by the US Securities and Exchange Commission (SEC) over allegations of failing to disclose his stake in Twitter in a timely manner.
In March 2022, Musk acquired a 5 percent stake in Twitter and later increased it to 9.2 percent, but delayed disclosing the information until April 2022.
Musk initially denied any intention of acquiring or taking over Twitter, but later made a takeover offer for the social media platform.
The SEC began investigating Musk's Twitter stake disclosure in May 2022 and later sued him to compel testimony, which Musk initially refused.
Multiple lawsuits have been filed against Musk by shareholders alleging stock market manipulation in relation to his Twitter dealings.
A court summons was delivered to Musk at SpaceX headquarters, where security guards reportedly refused to accept the documents.
Musk faces allegations of underpaying by at least $150 million for shares purchased after he failed to disclose his ownership within the required time frame.
The legal battle between Musk and the SEC dates back to 2018 when Musk's tweet about taking Tesla private led to penalties and his removal as Tesla chairman.
Despite the legal challenges, Musk maintains his CEO role at Tesla and faces a deadline to respond to the latest SEC allegations by April 4.
Musk has a history of contentious relations with the SEC, including insults and public statements undermining the authority of the regulatory agency.
