The Supreme Court is the highest legal authority in the US, and the decision to take on TikTok’s case is significant as it only hears 100 or so cases a year out of the more than 7,000 petitions it receives.
TikTok had previously argued that the attempt to ban it was unconstitutional because it would impact the free speech of its users in the country.
TikTok said Wednesday it was pleased with the Supreme Court’s order.
“We believe the Court will find the TikTok ban unconstitutional so the over 170 million Americans on our platform can continue to exercise their free speech rights,” a TikTok spokesperson said in a statement to the BBC.
The appeal sets up a clash between free speech and national security, according to University of Richmond law professor Carl Tobias.
“The appeals court found that national security was stronger than the First Amendment contentions. However, the Justices will scrutinize the potentially conflicting, but significant, values,” Mr Tobias said in an email.
While it is difficult to predict the outcome, Cornell professor Sarah Kreps said it would be surprising to the court to overturn the prior rulings and go against the wills of both congress and the White House.
“The case has already gone through the executive branch, the legislative branch, and the lower court, all of which upheld the argument that TikTok’s ownership by China-based ByteDance poses a national security risk,” Dr Kreps said.
