Social media took another hit Nov. 15 after a federal judge allowed most of the public nuisance claims brought by school districts in the addiction cases to move forward.

U.S. District Judge Yvonne Gonzalez Rogers of the Northern District of California found on Nov. 15 that school districts in 15 of the 19 states at issue could pursue public nuisance claims that social media sites, such as Instagram and TikTok, created a mental health crisis among the nation’s youth. The ruling is the fourth dismissal order from Gonzalez Rogers in the social media addiction multidistrict litigation and is contrary to a June 7 public nuisance decision by a Los Angeles judge in parallel litigation in California state courts.
