The US Supreme Court today struck down a provision in US law that let debt collectors make robocalls to cell phones, ruling that the law violates the First Amendment by favoring debt-collection speech over other speech.

The Telephone Consumer Protection Act (TCPA) of 1991 prohibits "almost all robocalls to cell phones," but Congress in 2015 amended the law to add "a new government-debt exception that allows robocalls made solely to collect a debt owed to or guaranteed by the United States," the Supreme Court noted in today's ruling. The opinion was written by Justice Brett Kavanaugh.
