United States v. Heppner: AI-Generated Documents Not Protected by the Attorney-Client Privilege

AI

Artificial intelligence is fundamentally changing how we work, research, and communicate. But if you are facing a legal issue, turning to a public AI chatbot for answers could permanently damage your case.

In a recent landmark decision, United States v. Heppner, a federal judge ruled that a defendant’s conversations with a generative AI platform were not protected by attorney-client privilege or the work product doctrine.

Here is what you need to know about the case and why your first call should always be to a human attorney.

The Background of Heppner

Federal prosecutors charged Bradley Heppner with various criminal offenses related to an alleged fraud scheme. After learning he was under investigation, Heppner—acting entirely on his own—used Claude, a publicly available consumer AI platform, to analyze his potential defense strategies and legal exposure.

Heppner later handed these AI-generated documents over to his defense attorneys. When the government discovered the materials during a search of his home, Heppner's legal team tried to block prosecutors from seeing them, arguing the documents were protected by attorney-client privilege and the work product doctrine.

The court completely rejected that argument.

The Court’s Ruling

Judge Jed S. Rakoff applied longstanding legal principles to this new technology, ruling that the government could access the AI-generated documents. The court's reasoning broke down into a few critical points:

  • AI is not a lawyer: Attorney-client privilege only covers communication between a client and an actual attorney. Because the AI platform is not a licensed legal professional, the privilege simply does not attach.
  • No expectation of confidentiality: The core of attorney-client privilege is privacy. The court noted that the AI platform’s terms of service allowed the company to collect user inputs, review them, and use them to train its models. By voluntarily sharing his legal strategy with a third-party platform, Heppner destroyed any reasonable expectation of confidentiality.
  • No retroactive privilege: Heppner tried to argue that because he eventually gave the AI documents to his lawyers, they became privileged. The court clarified that you cannot retroactively "cloak" a non-privileged document in privilege just by handing it to your attorney after the fact.
  • The work product doctrine requires attorney direction: While the work product doctrine protects materials prepared in anticipation of litigation, it generally requires those materials to be prepared by or at the direction of legal counsel. Because Heppner acted on his own without his lawyers' instruction, the documents reflected his own independent research, not his attorneys' mental impressions or strategy.

What This Means for You

At Nicholson & Hall, PLLC, we understand the temptation to run a quick search or ask a chatbot to explain your legal exposure. However, the Heppner decision serves as a massive wake-up call. Here is how this impacts you as a potential client:

1. Keep Your Legal Matters Offline

Treat public AI tools like ChatGPT or Claude as if you are talking to a stranger in a crowded coffee shop. Anything you type into a public prompt—names, dates, financial figures, or admissions—could potentially be subpoenaed by opposing counsel or the government.

2. Wait for Attorney Direction

If there is a legitimate reason to use technology or AI to organize your thoughts or evidence, let us guide that process. If an attorney directs you to use a secure, closed-enterprise tool as part of a legal strategy, those materials have a much higher chance of being protected under the work product doctrine. Doing it on your own strips away those protections.

3. Privilege Requires a Human Connection

The law has not changed just because the tools have. Attorney-client privilege is sacred, but it only exists when you communicate directly and securely with your legal counsel.
