The Supreme Court remained the center of attention in the legal news cycle on April 16, even without an obvious blockbuster merits opinion emerging from the day’s accessible reporting.

The dispute centers on a statute requiring ByteDance to divest TikTok or face restrictions on the app’s U.S. operations, with challengers arguing the law unlawfully burdens speech and exceeds constitutional limits.

The Court’s involvement is significant not just because of TikTok’s reach, but because the case tests how far the political branches can go when regulating a communications platform on national security grounds.
