A US appeals court will hear arguments in the Trump administration's appeal of a judge's order that blocked a ban on Chinese-owned TikTok from domestic app stores.
US District Judge Carl Nichols had blocked the Commerce Department order hours before it was due to prohibit new downloads of the short video-sharing app in September.
The ban would have required Apple Inc and Alphabet's Google to remove the app from their stores, preventing new users from downloading it or existing users downloading updated versions. It would not have stopped existing users from accessing the app on their devices.
The appeals panel was due to hear arguments on Monday, December 14, with the Trump administration claiming TikTok poses national security concerns as the personal data of US users could be obtained by China's government. TikTok, which has over 100 million US users, denies the allegation.
On December 4, the Trump administration opted not to grant TikTok-owner ByteDance a new extension of an order requiring the company to divest TikTok's US assets, but talks have continued over the short video-sharing app's fate.
President Donald Trump's order issued in August gave the Justice Department the power to enforce the divestiture order once the deadline expired, but over a week has passed and the department has not gone to court to force them to comply.
Under pressure from the US Government, ByteDance has been in talks for months to finalise a deal with Walmart Inc and Oracle Corp to shift TikTok's US assets into a new entity aimed to satisfy the divestiture order.
But on December 7, Judge Nichols separately granted a preliminary injunction blocking the US Commerce Department from imposing restrictions on TikTok that would have effectively barred its use in the United States.
Nichols issued an order in a suit filed by ByteDance after US judge Wendy Beetlestone in Pennsylvania had earlier blocked the same restrictions set to take effect on November 12.
The Commerce Department had sought to bar data hosting within the United States for TikTok, its content delivery services and other technical transactions.
