President Donald Trump cannot block users on Twitter, according to a ruling by a federal appeals court, which found that the action violates the First Amendment rights of users.

In a 3-0 decision, the 2nd U.S. Circuit Court of Appeals in Manhattan determined that the Constitution does not permit Trump to limit access to his account, which otherwise is open to the public.

In its response to the decision, the U.S. Department of Justice called the ruling “fundamentally misconceived.” The DOJ argued that Trump is on Twitter in a personal capacity, not as a public government figure.

Seven Twitter users filed the original lawsuit via the Knight First Amendment Institute after Trump blocked them from his account in 2017. A federal judge ruled in their favor in May 2018, saying Trump and plaintiffs engaged in “unconstitutional viewpoint discrimination” by limiting certain users’ access to his social media account because he disagreed with their speech.
