Former US president Donald Trump has asked an appeals court to revive his lawsuit against Twitter, challenging his permanent suspension from the platform.

Mr Trump was suspended from Twitter after his supporters attacked the US Capitol on January 6, 2021.

Lawyers for Mr Trump, a Republican, told the San Francisco-based 9th US Circuit Court of Appeals in a filing that the Twitter ban marked “overtly partisan censorship” and was “contrary to First Amendment principles deeply rooted in American history and law”.

His lawsuit seeks compensatory and punitive damages and a court order requiring Twitter to “immediately reinstate” his account which was permanently suspended on January 8, 2021.

Mr Trump has vowed to keep posting to his own Truth Social media platform.

Twitter’s new owner, billionaire Elon Musk, has said he would reinstate Mr Trump’s account.

A spokesperson for Mr Trump did not immediately respond to a message seeking comment and a Twitter spokesperson did not immediately reply.

A lawyer for Mr Trump, John Coale in Washington, told Reuters on Monday “we want him to have the right to get back on” Twitter.

Twitter said last year it had permanently suspended Mr Trump’s account “due to the risk of further incitement of violence” after his supporters stormed the US Capitol as it was preparing to certify Democrat Joe Biden’s presidential win.

San Francisco-based US District Judge James Donato in May dismissed Trump’s claim that his ban from Twitter violated speech protections accorded under the US Constitution’s First Amendment.

Justice Donato also denied Trump’s claim that Twitter was serving as a “state actor” when it banned his account.
