Columbus will have to answer in court for the 2024 ransomware attack that exposed the personal data of half a million people. An appeals court has rejected the city's attempt to block the class action lawsuit.
Columbus tried to shield itself from its own residents. That shield just broke. The 10th District Court of Appeals ruled the class action lawsuit over the city's 2024 ransomware breach can move forward. The city's push for immunity failed. The decision was unanimous.
Half a million people had their private data dumped on the dark web. That's the core of this fight. Independent sources confirm the July 2024 ransomware attack exposed personal details of about 500,000 residents and city workers. The leaked files included names, addresses, and other sensitive information. The breach happened on July 18, 2024. It now stands as a key case in legal and regulatory reviews of city cyber risk.
The Department of Technology, now run by an interim leader, faces tough questions. It's not just about the breach. It's about what happened after. The plaintiffs say Columbus had a duty to protect the personal data it collects. The city denied responsibility. It wanted the lawsuit thrown out.
By 2026, major class actions and appellate decisions in data breach litigation continue to underscore the ongoing legal significance of immunity, standing, and the admissibility of collective claims in cyber incident cases.
Last October, a Franklin County judge sided with the city. The judge cited municipal immunity, even after seeing evidence that victims suffered harm. That ruling is now gone. The appeals court reversed it. The message is blunt: this case deserves a hearing. The facts need daylight.
Spencer Meador, attorney at Cooper Elliott for the plaintiffs, spoke plainly: "The city asked the court to end this case before we were able to investigate it. And so the court of appeals actually just came out with a decision saying that it's too early for this case to be dismissed and that our firms are allowed to find some answers." Meador said they will keep pushing for answers for both residents and city workers whose data was exposed.
The Department of Technology issued a short statement. The city said it respects the court's decision. It also confirmed that more legal steps, including a possible appeal to the Supreme Court of Ohio, are under review with city lawyers and outside counsel.
This fight comes as ransomware attacks keep rising worldwide. Earlier reports show organizations everywhere are struggling to recover. Costs are climbing. Progress is slow, even as defenses improve. In the US, Reuters has tracked a sharp rise in both cyberattacks and lawsuits. Data breach cases are now a constant threat for cities and companies alike.
The appeals court's move changes the game for public sector cybersecurity. Columbus can't hide behind legal shields anymore. The city will face questions about its data protection failures. Half a million people are watching. So are other cities. The old days of automatic immunity for public agencies after digital blunders may be ending. This case will test how far that change goes.
