SCOTUS ISP Liability Ruling Explained: What Cox v. Sony Means for Piracy, ISPs, and You
Can Your ISP Cut Off Your Internet for Piracy? The Supreme Court Just Said No
If you've ever gotten one of those ominous copyright notices from your internet provider, the kind that makes you wonder if you're about to lose your Netflix-and-chill privileges forever, you can probably relax a little. The Supreme Court just handed down a ruling that fundamentally changes the game for ISPs, copyright holders, and anyone who's ever worried about getting their internet shut off over a piracy accusation.
On March 25, 2026, the Court issued its decision in Cox Communications v. Sony Music Entertainment — and in case you missed the headline, ISPs won. Big time. Then, just last week, the Court doubled down, vacating a separate $46 million verdict against Texas-based Grande Communications and telling the Fifth Circuit to try again, this time using the Cox playbook.
Here's what happened, why it matters, and, most importantly, what it actually means for you.
The Ruling That Changed Everything, In Plain English
What the 5th Circuit Said (And Why It Scared ISPs)
Before we get to the good stuff, let's rewind to what the Fifth Circuit Court of Appeals had previously decided, because honestly, it's what made this Supreme Court ruling such a big deal.
The Fifth Circuit had held that Grande Communications was liable for contributory copyright infringement essentially because it knew some of its subscribers were pirating music and didn't terminate their internet service. The logic went something like this: if you know someone's using your service to break the law and you keep providing that service anyway, you're helping them do it. Makes intuitive sense, right?
Except here's the problem: that logic, taken to its natural conclusion, would turn every ISP in America into a de facto copyright police force. Get enough infringement notices, or honestly, just a few from a particularly aggressive rights holder, and you'd have to choose between losing a paying customer or risking a multi-million-dollar lawsuit. Not exactly a fun position to be in.
What SCOTUS Actually Decided
The Supreme Court looked at that reasoning and, in a 9-0 unanimous decision, said: Nope. That's not how this works.
The core holding is surprisingly straightforward: An ISP isn't liable for its customers' copyright infringement just because it knows it's happening and keeps providing service. Knowledge alone isn't enough.
Justice Clarence Thomas, writing for the majority, put it plainly: "Under our precedents, a company is not 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."
The Two-Part Test: Inducement and "Tailored to Infringement"
If you want to hold an ISP liable for what its users do, you now need to clear a much higher bar. According to the Court, there are exactly two ways to prove contributory infringement:
- Affirmative inducement: The ISP actively encouraged users to pirate. (Example: running ads that say "Use our lightning-fast internet to download all the free movies you want!")
- Service tailored to infringement: The service itself was designed specifically for piracy and has no substantial legitimate use. (Example: a peer-to-peer network that exists solely to distribute pirated content, like Grokster back in the day.)
Internet access, obviously, has tons of lawful uses. Email, remote work, streaming legit services, online banking, you name it. So that second prong is essentially a non-starter for any mainstream ISP. And unless your internet provider is out here actively advertising "pirate faster with us," the first prong is off the table too.
The bar just got dramatically higher. And for ISPs, that's a huge relief.
The Road to the Supreme Court, Cox v. Sony, Explained
The $1 Billion Lawsuit That Started It All
This whole saga began back in 2018, when Sony Music and dozens of other major record labels sued Cox Communications, one of the largest broadband providers in the country, for contributory and vicarious copyright infringement.
The labels' argument? Between 2013 and 2014, Cox received thousands of infringement notices identifying specific subscriber accounts that had been repeatedly caught pirating music. And what did Cox do about it? According to the evidence, it terminated... wait for it... 32 customers. Thirty-two. Meanwhile, it terminated hundreds of thousands of subscribers for nonpayment during the same period.
The labels argued that Cox was essentially protecting revenue by keeping known infringers on the network. A jury agreed, and awarded the music industry $1 billion in statutory damages. Billion with a B.
Why the Fourth Circuit Got It Wrong (According to SCOTUS)
Cox appealed, and the Fourth Circuit split the baby: it threw out the vicarious liability finding but upheld the contributory infringement verdict. The appeals court reasoned that knowingly supplying a service to someone you believe will use it to infringe is "exactly the sort of culpable conduct sufficient for contributory infringement."
The Supreme Court granted certiorari in June 2025, and when the opinion finally dropped, it didn't just tweak the Fourth Circuit's reasoning. It blew it up entirely.
The Court held that the Fourth Circuit's approach conflicted with decades of precedent, including the foundational Sony v. Universal City Studios case from 1984 (the "Betamax case") and MGM v. Grokster from 2005. Failing to terminate known infringing accounts, the Court concluded, is not the same as intending infringement.
The 7-2 Decision: Thomas Writes, Sotomayor Concurs (Reluctantly)
While the outcome was unanimous (9-0) in favor of Cox, the reasoning was actually a 7-2 split. Justice Thomas wrote for seven justices, but Justice Sotomayor, joined by Justice Jackson, concurred in the judgment only.
And Sotomayor did not hold back.
She agreed Cox shouldn't be liable on these facts, but she blasted the majority for going too far. The majority's rigid two-part framework, she argued, "permits ISPs to sell an internet connection to every single infringer who wants one without fear of liability and without lifting a finger to prevent infringement."
She also warned that the ruling effectively renders the DMCA's safe harbor provisions obsolete, because if ISPs face virtually no risk of secondary liability anyway, what incentive do they have to maintain repeat-infringer policies?
It's a fair critique. And it's one that will likely fuel future legal battles. But for now, the majority opinion is the law of the land.
Wait, Who's Grande? The Ripple Effect Explained
Grande Communications and the $46 Million Verdict
You might be wondering: the headline mentioned a 5th Circuit ruling being overturned, but we've been talking about Cox and the Fourth Circuit. What gives?
Here's where the story gets interesting, and where the ripple effects become crystal clear.
Grande Communications is a Texas-based broadband provider (a subsidiary of Astound Broadband) that got sued by the same constellation of music labels, UMG, Sony, Warner, and others, under very similar facts. The labels argued Grande was liable for not terminating repeat infringers. A jury agreed, and the Fifth Circuit upheld a $46 million penalty against Grande.
SCOTUS Says "Try Again", The Vacate and Remand Order
After issuing the Cox decision in March, the Supreme Court didn't wait long to show it meant business. On April 6, 2026, the Court granted Grande's petition for certiorari, vacated the Fifth Circuit's judgment, and remanded the case back for reconsideration "in light of" Cox v. Sony.
Translation: "Fifth Circuit, you got this wrong. Go back and try again using the new rules we just laid out."
Why This Second Case Proves the Ruling Has Teeth
This vacate-and-remand order is huge for two reasons.
First, it confirms the Cox ruling isn't some narrow, fact-specific decision. It's a precedent that applies across the board, including to cases that were already decided and seemed settled.
Second, it sends an unmistakable signal to lower courts: the old way of thinking about ISP liability is dead. Knowledge plus inaction doesn't equal infringement anymore.
The Grande case will now go back to the Fifth Circuit, which will almost certainly have to reverse its earlier position. And if it doesn't? Well, SCOTUS will be waiting.
What This Actually Means, For Everyone Involved
For Internet Users (Spoiler: You're Probably Fine)
Let's start with the question you actually care about: Can I get my internet shut off for torrenting?
The short answer: Your ISP almost certainly won't be forced to terminate your service over copyright notices, because the legal pressure that used to exist just evaporated.
That doesn't mean ISPs can't terminate you. Your terms of service almost certainly say they can cut you off for violating copyright law, and they might still choose to do so. But the multi-billion-dollar legal threat that was hanging over their heads if they didn't terminate repeat infringers? That's gone now.
What about getting sued directly? That's still possible, copyright holders can (and do) sue individual infringers. But those cases are expensive to bring and rarely worth it unless you're running a major piracy operation. The average person downloading a movie or album is still unlikely to face legal action.
The bottom line: the risk of losing your internet over a few copyright notices just dropped dramatically. Not zero, but dramatically.
For ISPs (The Legal Shield Just Got Stronger)
For internet providers, this ruling is nothing short of a game-changer.
Under the majority's framework, ISPs face substantial insulation from secondary copyright liability. Unless they actively induce infringement or provide a service specifically tailored to facilitate it, they're in the clear, regardless of what they know about their users' activities.
This means ISPs can breathe easier about maintaining repeat-infringer policies. They can still choose to terminate users, warn them, or do nothing at all, and the choice is now largely a business decision rather than a legal obligation.
That said, there's a wrinkle: the DMCA's safe harbor provision still exists, and ISPs that want those protections still need to maintain some form of repeat-infringer policy. But as the concurrence pointed out, the safe harbor may now matter a lot less, because the underlying liability it protects against has been dramatically narrowed.
For Copyright Holders (The Path Forward Just Got Narrower)
If you're a record label, movie studio, or other content owner, this ruling is... not great.
The music industry spent years building a legal strategy centered on holding ISPs accountable as the "chokepoint" for online piracy. The argument was simple: ISPs are the only entities that can effectively stop mass infringement, because they control the pipes. Sue a million individuals? Impossible. Pressure a few dozen ISPs? Doable.
The Supreme Court just rejected that entire theory.
Going forward, copyright holders have a much narrower path to holding ISPs liable. They'll need evidence that an ISP actively encouraged piracy, not just that it looked the other way. And good luck finding a mainstream ISP dumb enough to put "pirate faster" in its marketing materials.
What about suing individuals? Still possible, but expensive and PR-risky. What about pressuring ISPs voluntarily? That might be the new playbook, but with the legal hammer gone, ISPs have less reason to play ball.
The DMCA Safe Harbor Question: Alive, Dead, or Just Confused?
One of the most interesting unresolved questions is what this means for the DMCA's safe harbor provisions.
Under Section 512(i) of the DMCA, ISPs that want protection from monetary damages need to adopt and "reasonably implement" a policy for terminating repeat infringers. Sony argued that if ISPs face no liability for keeping known infringers, that provision becomes meaningless.
The Court disagreed, but the concurrence sided with Sony on this point, warning that the majority's framework "renders the safe harbor provisions in the DMCA effectively obsolete."
This tension isn't going away. Future cases will likely test exactly what ISPs still need to do to qualify for safe harbor protection, and whether that requirement has any real teeth left.
Is This the End of Anti-Piracy Efforts? Not Exactly
What ISPs Can Still Do (And Probably Will)
Don't expect ISPs to suddenly start advertising "pirate-friendly internet" or abandoning all enforcement. Most will likely maintain some version of their current policies for a few reasons:
- Business reputation: No ISP wants to be seen as "the one that welcomes pirates."
- DMCA safe harbor: Even if the liability risk is lower, the safe harbor still has value.
- Bandwidth management: Piracy consumes network resources. ISPs have independent reasons to discourage it.
- Future legal shifts: This ruling could be refined or limited by future cases. No one wants to be caught flat-footed.
What you might see is a shift toward more educational warnings rather than aggressive termination policies. The "three strikes and you're out" approach may soften into "we sent you a letter, please stop."
The International Picture, Where the U.S. Stands Now
This ruling also puts the United States in a somewhat unique position globally.
In many countries, particularly in Europe, ISPs face more robust obligations to address piracy on their networks. The EU's Copyright Directive, for instance, creates a framework that's generally more favorable to rights holders.
The U.S. approach, post-Cox, is notably more ISP-friendly. Whether that creates international friction (or makes the U.S. a more attractive jurisdiction for internet infrastructure) remains to be seen.
Unresolved Questions and What Comes Next
This isn't the end of the story. Here's what to watch going forward:
- The Grande remand: How the Fifth Circuit applies the Cox framework will set important precedent.
- The Verizon case: A $2 billion lawsuit against Verizon has been paused pending Cox. Expect that to resume, and likely end differently now.
- Legislative response: Could Congress step in? The music industry has powerful lobbyists. Don't rule out a legislative fix.
- Sotomayor's concurrence: Her critique could influence how lower courts interpret the majority opinion, or provide a roadmap for future plaintiffs to argue their cases differently.
The legal landscape just shifted dramatically, but it hasn't stopped moving.
The Internet Just Got a Little Freer
Here's the bottom line, in the simplest terms possible: ISPs are not copyright cops, and knowing about piracy isn't the same as causing it.
The Supreme Court's decision in Cox v. Sony — and its immediate application to the Grande case, draws a bright line that protects internet providers from being dragged into billion-dollar lawsuits over what their customers do online. It's a win for ISPs, a win for anyone who believes internet access shouldn't come with a built-in surveillance apparatus, and honestly, a win for common sense.
For internet users, the practical takeaway is simple: the fear of losing your connection over a copyright notice just got a lot less real. ISPs still have policies, and they still can take action, but the legal gun to their head has been removed.
That doesn't mean piracy is suddenly legal or consequence-free. Copyright holders still have options, and individual infringers can still face legal action. But the era of holding ISPs liable simply for providing the pipes? That era is over.
