On March 25, 2026, the U.S. Supreme Court unanimously ruled in favor of Cox Communications, overturning a previous jury verdict that had found the internet service provider (ISP) liable for its customers’ unauthorized music downloads. The Court determined that mere knowledge of infringement does not equate to intent to promote it, thereby absolving Cox of contributory copyright infringement.
The case originated when a coalition of record labels, including Sony Music Entertainment, alleged that Cox failed to take adequate measures to prevent its subscribers from engaging in illegal music downloads. A jury had initially found Cox liable and imposed a $1 billion fine, which was partially upheld by the 4th U.S. Circuit Court of Appeals, although the size of the award was reduced.

In its defense, Cox argued that holding ISPs accountable for the actions of their users could lead to widespread disruptions in internet access. The company warned that it might be compelled to terminate services for households, hospitals, universities, and businesses based on minimal allegations of infringement. Cox Communications serves over 6 million customers across more than a dozen states. ([apnews.com](https://apnews.com/article/af4064940cb87cdee3b9dc7839376d7f?utm_source=openai))
The Supreme Court’s decision underscores the legal distinction between an ISP’s awareness of potential infringement and an active intent to promote such activities. This ruling provides clarity on the responsibilities of ISPs in monitoring and addressing copyright violations by their users, emphasizing that liability requires more than just knowledge of infringement.
