The federal appeals court that last week rejected TikTok's attempt to overthrow its pending ban denied the company's request Friday that sought to pause the ruling and the Jan. 19 deadline for a sale.
The company, which has been forced by a federal law to sell to a new owner or be banned in the U.S., requested the emergency pause earlier in the week arguing it would afford the Supreme Court time to determine whether it should review the law.
However, the D.C. Circuit judges said that Congress made a "deliberate choice" to set a 270-day time frame for the sale-or-ban, "subject to one (and only one) extension."
"The petitioners have not identified any case in which a court, after rejecting a constitutional challenge to an Act of Congress, has enjoined the Act from going into effect while review is sought in the Supreme Court," the judges wrote in the unsigned order.

The Justice Department asked the court to reject TikTok's request for a temporary injunction.
"The Court is familiar with the relevant facts and law and has definitively rejected petitioners’ constitutional claims in a thorough decision that recognizes the critical national-security interests underlying the Act," the DOJ's attorneys said.
The Justice Department did not immediately comment on the decision either.
The case would have to go to the Supreme Court if TikTok chooses to appeal, which could delay the Jan. 19 deadline.
President Joe Biden signed the Protecting Americans from Foreign Adversary Controlled Applications Act, which was part of a massive, $95 billion foreign aid package passed by Congress, on April 24.
As part of the act, TikTok, which has over 170 million U.S. users, is forced to sell the company from its current Chinese-based owner ByteDance.

ByteDance rebutted those allegations in its lawsuit, arguing there has been no tangible evidence that the app poses any security risk and filed a lawsuit against the Justice Department in May.
The law has prompted major protests from TikTok's American users who have defended the app.
President-elect Donald Trump once proposed a TikTok ban when he was in office but has changed his stance and signaled he would reverse the ban once in office. A reversal, however, would require approval from both houses of Congress.
