How AI Is Flooding Courts With More Cases and Fake Citations

Walking past the Daley Center on a Tuesday morning, you can usually feel the palpable tension of a city that lives and breathes litigation. Chicago has always been a town of heavy hitters—powerhouse law firms in the Loop and a court system that handles some of the most complex caseloads in the Midwest. But lately, there is a new, invisible player entering the courtroom, and it isn’t wearing a suit. It’s generative AI, and while it promises efficiency, it’s currently acting more like a digital arsonist in the halls of justice.

We’ve all seen the headlines about AI “hallucinations,” but when those hallucinations migrate from a quirky chatbot conversation into a formal filing at the Cook County Circuit Court, the stakes shift from amusing to catastrophic. The recent trend is alarming: a surge of both seasoned attorneys and pro se litigants—people representing themselves—are using tools like ChatGPT to draft persuasive arguments. The problem is that these models are designed to be convincing, not necessarily accurate. They are essentially “guessing” the next most likely word, which, in the context of legal citations, means they often invent entirely fake case law that looks perfectly authentic in Bluebook format.

The Hallucination Epidemic: From Global Trends to Local Dockets

This isn’t just a few isolated incidents of laziness; we are looking at a systemic crisis. According to data maintained by Damien Charlotin of HEC Paris’s Smart Law Hub, as of early 2026, there have been 1,227 documented cases globally where generative AI produced hallucinated content submitted to courts. The United States is the epicenter of this trend, accounting for 811 of those cases. For those of us in Chicago, this is a warning shot. When a top-tier firm like Sullivan & Cromwell has to apologize for filing fictitious case names and fabricated quotes, it proves that no one is immune—not even the firms with the deepest pockets and the most prestigious offices overlooking the lake.

The sheer volume of the problem is compounded by a shift in who is filing. Research from MIT’s Anand Shah and USC’s Joshua Levy indicates a startling jump in pro se civil cases, rising from a steady 11% to roughly 18% in the post-AI era. On the surface, this looks like the democratization of law—giving the average resident of the South Side or the Northwest Side the tools to challenge a corporation or a landlord without spending thousands on a retainer. However, this “empowerment” comes with a steep price. Many of these litigants are submitting filings that are 18% AI-generated, often without a human lawyer to verify the citations. The result? A court system that is being flooded with “templated” litigation that may be based on a complete fiction.

Here is the rub: while the cases aren’t necessarily resolving faster or slower, the “back-and-forth” between opposing parties has exploded. Shah notes that the number of filings judges must review has increased by roughly 158%. Imagine being a judge in the Cook County system, already dealing with a notorious backlog, and suddenly having to verify every single citation in a 30-page brief because there’s a high probability the “precedent” cited doesn’t actually exist. It’s a recipe for burnout and judicial gridlock.

The Second-Order Effects on Chicago’s Legal Ecosystem

Beyond the immediate risk of sanctions—like the $30,000 penalty recently imposed by the Sixth Circuit—there is a deeper socio-economic shift happening. We are seeing a tension between access to justice and the integrity of the record. Institutions like the Northwestern University Pritzker School of Law and the University of Chicago Law School are now tasked with rethinking how they train the next generation of lawyers. The skill of “legal research” is shifting from finding the case to *verifying* that the case actually exists.

the rise of AI-driven filings is creating a new class of “legal noise.” When the barrier to entry for filing a lawsuit drops to the cost of a monthly AI subscription, the courts may be overwhelmed by low-merit cases that are simply “well-written” by an LLM. This forces actual victims of injustice to wait longer for their day in court because the docket is clogged with AI-generated fluff. If you are trying to navigate urban court systems today, you’re not just fighting the opposing counsel; you’re fighting an algorithm that can generate a hundred pages of plausible-sounding nonsense in seconds.

The Local Resource Guide: Protecting Your Interests in the AI Era

Given my background in analyzing the intersection of technology and urban infrastructure, it’s clear that the “YOLO” approach to AI in the courts is a disaster waiting to happen. If you are a business owner, a tenant, or a legal professional in the Chicago area, you cannot afford to trust a chatbot with your legal standing. The risk of being sanctioned or losing a case due to a “hallucinated” statute is simply too high.

If this trend impacts you, you need to move beyond generic AI tools and engage with specific types of local expertise. Here are the three archetypes of professionals you should be looking for in the Windy City right now:

AI-Literate Legal Auditors

These aren’t just lawyers; they are specialists who bridge the gap between legal practice and data science. When hiring an auditor, look for professionals who can perform “citation scrubs” on AI-assisted drafts. They should have a documented process for cross-referencing every AI-generated claim against official databases like Westlaw or LexisNexis. Avoid anyone who claims AI is “100% accurate” if you use the right prompts—that’s a red flag.

Pro Se Strategic Consultants

For those who cannot afford a full legal team but want to avoid the pitfalls of AI-generated filings, these consultants provide the “human layer” of verification. Look for practitioners who are familiar with the specific local rules of the Cook County Circuit Court and the Illinois State Bar Association guidelines. The goal here is to use AI for the *structure* of the argument but rely on a human for the *substance* and the citations.

Legal Technology Compliance Officers

For mid-sized Chicago law firms, the risk is internal. You need specialists who can implement “closed-loop” AI systems—tools that only reference a firm’s own verified document library rather than the open web. When vetting these experts, ask about their experience with “Retrieval-Augmented Generation” (RAG) and how they prevent the model from drifting into fabrication. They should be able to show you a workflow that mandates human-in-the-loop verification before any document hits a court’s e-filing system.

The transition to an AI-augmented legal system is inevitable, but as we’ve seen, the “move quick and break things” mentality doesn’t work when the things being broken are the foundations of the rule of law.
