The US Supreme Court has dealt a blow to copyright holders by ruling that Internet service providers can't be held responsible for their customers’ illegal music downloads unless they actively encourage or help piracy. The unanimous decision protects ISPs from sweeping liability for their users’ actions online.

Background of the Case

For years, copyright owners have pushed Internet providers to crack down on piracy through aggressive user bans and strict network monitoring. Sony Music Entertainment took Cox Communications to court, claiming the ISP was partly responsible for widespread illegal music sharing on its network. Cox faced a $1 billion penalty in 2019 after being found liable for contributory copyright infringement, though that hefty damages award was overturned in 2024.

Despite the overturned fine, a federal appeals court still held Cox accountable, leading the telecom company to appeal to the highest court. The Supreme Court agreed to hear the case, with oral arguments taking place in December 2025.

The Supreme Court’s Ruling

In a unanimous decision, the Court sided with Cox, ruling that ISPs can't be held liable for copyright infringement solely because they provide internet access to users who break the law. Justice Clarence Thomas authored the opinion, stating that liability only applies if an ISP actively induces or helps infringement.

"A company isn't liable as a copyright infringer for merely providing a service to the general public with knowledge that it will be used by some to infringe copyrights," Thomas wrote. This means ISPs don’t have to police their networks by mass suspending or disconnecting users accused of piracy to avoid legal consequences.

Chief Justice John Roberts and five other justices joined Thomas’s majority opinion. Justices Sonia Sotomayor and Ketanji Brown Jackson agreed with the outcome but expressed concerns about the ruling limiting liability too much. Sotomayor emphasised that contributory liability requires intent to promote infringement, which Cox lacked.

Implications for ISPs and Copyright Enforcement

This ruling takes a lot of pressure off ISPs, who used to worry about expensive lawsuits if they didn’t crack down hard on piracy.

Had the Court ruled against Cox, providers would likely have had to enforce strict monitoring and ban users, which could have hurt privacy and internet freedom.

Still, this decision makes it tougher for copyright holders to combat piracy. Without the ability to hold ISPs responsible unless they directly encourage infringement, rights holders may find it harder to stop illegal sharing, especially on large networks.

Experts say copyright owners will probably go after individual pirates and file-sharing sites instead of relying on ISPs to police users. For ISPs, the ruling clarifies their legal obligations and protects them from becoming overburdened policing agents.

Historical Context and Digital Copyright Law

The case touches on the Digital Millennium Copyright Act (DMCA), a 1998 law that shields ISPs from liability if they promptly respond to copyright infringement notices. The DMCA’s safe harbour provisions aim to balance copyright enforcement with the open nature of the internet.

Critics argue that requiring ISPs to police users risks stifling innovation and user privacy. This ruling backs up the DMCA’s protections, making clear ISPs aren’t liable if they didn’t actively cause infringement.

But the ruling doesn’t settle how courts will handle intent and inducement in future cases. It raises the bar for holding providers accountable, showing that just knowing about infringement isn’t enough.

For Australian ISPs and copyright holders, the ruling is being watched closely. While Australian copyright law differs, the case highlights global tensions between protecting creative works and maintaining a free internet. Similar debates are ongoing here about balancing enforcement with user rights.

Justice Thomas summed it up: "The intent required for contributory liability can be shown only if the party induced the infringement or the provided service is tailored to that infringement." Cox didn’t cross that line, and neither will many other ISPs, thanks to today’s ruling.
