The Supreme Court will hear arguments next month over the constitutionality of the federal law that could ban TikTok in the U.S. if its Chinese parent company doesn’t sell it.

The Supreme Court agreed to hear arguments on whether a bill that could ban TikTok violates the First Amendment. The arguments will take place on January 10th, just over a week before a potential ban could take effect.

The Supreme Court will decide whether or not TikTok will be banned in the U.S. unless it separates from parent company ByteDance, as justices announced Wednesday they will hear TikTok’s challenge to the federal law—scheduling oral arguments in January, right before the ban is slated to take effect.
