U.S. Supreme Court backs Facebook in case about unwanted texting Published On U.S. Supreme Court backs Facebook in case about unwanted texting WASHINGTON (Reuters) -The U.S. Supreme Court on Thursday made it easier for businesses to pester consumers with phone calls or text messages by tossing out a lawsuit accusing Facebook Inc of violating a federal anti-robocall law. The justices, in a 9-0 decision authored by Justice Sonia Sotomayor, sided with Facebook over its argument that text messages the social media company sent did not violate a 1991 federal law called the Telephone Consumer Protection Act (TCPA). The case highlighted the challenge for the justices in applying outdated laws to modern technologies. The ruling sparked calls for the U.S. Congress to update the law, enacted three decades ago to curb telemarketing abuse by banning most unauthorized robocalls.
