Supreme Court ruling: Facebook's automated texts don't violate robocalling laws In a 9-0 decision authored by Justice Sonia Sotomayor, the Supreme Court barred a proposed lawsuit against Facebook over automated text messages. Listen - 01:41 James Martin/CNET The US Supreme Court on Thursday issued a unanimous ruling in favor of Facebook, finding that the social media giant isn't violating the 1991 Telephone Consumer Protection Act when it sends out automated text messages. The court noted that the 1991 law, which was written to curb robocalls, wasn't intended to apply to new, internet-based technologies. The ruling bars a proposed class action lawsuit against Facebook, which a federal judge had already tossed out in 2019. The plaintiffs, led by a Montana resident named Noah Duguid who had received numerous password reset texts from Facebook despite never using the service, appealed to the San Francisco-based 9th US Circuit Court of Appeals, where a judge ruled that Facebook's practices fell under the scope of the law, meaning that the lawsuit could proceed.
