A California federal judge has approved the Justice Department’s settlement allowing Hewlett Packard Enterprise’s $14 billion acquisition of Juniper Networks to move forward, rejecting objections from a coalition of state attorneys general and closing a closely watched chapter in federal merger enforcement.

The case, United States of America v. Hewlett Packard Enterprise Co. et al, drew unusual attention because the dispute was not just over the substance of the antitrust remedy, but also over whether the court should probe claims that outside lobbying may have influenced the DOJ’s settlement decision.

The Supreme Court’s decision to take up the challenge to the federal law targeting TikTok marks one of the most consequential intersections of national security, platform regulation, and First Amendment law in years. 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.
