9-0! SCOTUS Gives Immunity to ISPs Over Illegal Downloads

“Under our precedents, a company is not liable as a copyright infringer for merely providing a service to the public with knowledge that it will be used by some to infringe copyrights.”
So wrote Justice Clarence Thomas in the US Supreme Court decision Cox Communications vs. Sony Music released today that has wide-ranging implications.
A jury in 2019 had reached a $1 billion verdict against Cox, saying that it owed Sony Music and others for infringing on 10,000 copyrights, with both contributory and vicarious infringement. Contributory infringement involves knowing and contributing to an infringing act, while vicarious infringement means the party could have stopped it but instead benefitted.
The Trump administration backed Cox, while music, film and book publishers backed Sony.
This is a huge ruling, as it reaffirms that ISPs do not have liability for what their customers do. Just because someone transmits a torrent across an ISP’s network does not mean the ISP can be sued. If this ruling had gone the other way, it would have inevitably lead to mass surveillance, because every time someone logged on to the Internet, they were opening the ISP up to billions in damages.
