"Judge Rakoff issued an oral ruling that neither the attorney-client privilege nor the work product doctrine protected the AI-generated documents.12 The decision rests on traditional principles of privilege.

The attorney-client privilege protects (1) communications, (2) among only privileged parties, (3) made for the purpose of providing or obtaining legal advice.13 Importantly, the protection of the attorney-client privilege is lost if the communication is shared outside of the privileged parties.14 The party claiming privilege has the burden of showing that confidentiality was maintained.15 Judge Rakoff stated that the attorneyclient privilege did not apply because the communications were shared with a thirdparty tool that did not maintain confidentiality.16

Second, Judge Rakoff held that the work product doctrine did not protect the documents.17 The work product doctrine protects (1) legal work product, (2) discussing legal strategy, (3) prepared by or at the direction of legal counsel, (4) in anticipation of litigation.18 Judge Rakoff rejected Heppners arguments that the work product doctrine could apply because the AI-generated reports did not reflect the legal strategy of Heppners legal counsel, although they contained theories generated by the client and Claude.19 Since neither Heppner nor the AI tool are legal counsel, and Heppner was not working at the direction of Heppners legal counsel, the materials were not protected by the work product doctrine. Judge Rakoff noted that the AI tools disclaimer that users have no expectation of confidentiality also undermined the work product doctrine claim.20

"Reasons Privilege Failed

No attorney was involved. An AI tool is not a lawyer. It has no law license, owes no duty of loyalty, cannot form an attorney-client relationship, and is not bound by confidentiality obligations or professional responsibility rules. Discussing legal matters with an AI platform is legally no different from talking through your case with a friend.

Not for the purpose of obtaining legal advice. Anthropic's own public materials state that Claude follows the principle of choosing the "response that least gives the impression of giving specific legal advice." The tool explicitly disclaims providing legal services. You cannot claim you used a tool for legal advice when the tool itself says it does not provide it. Claude's terms were specifically highlighted by the government, which directly undermined the claim that Heppner was seeking legal advice from the tool.

Not confidential. This is the finding with the broadest implications. Anthropic's policy expressly states that user prompts and outputs may be disclosed to "governmental regulatory authorities" and used to train the AI model. Judge Rakoff found there was simply no reasonable expectation of confidentiality. As he put it, the tool "contains a provision that any information inputted is not confidential." This is not unique to Claude. OpenAI's privacy policy contains comparable provisions permitting data use for model training and disclosure in response to legal process.

And the distinction between free and paid plans matters less than many assume. Both Anthropic and OpenAI use conversations from free and individual paid plans (Claude Free, Pro, and Max; ChatGPT Free, Plus, and Pro) for model training by default. Users can opt out, but opting out of training does not eliminate the platforms' rights to disclose data to government authorities or in response to legal process. Only enterprise-tier agreements (ChatGPT Enterprise and Business; Claude's commercial and government plans) exclude user data from training by default and offer contractual confidentiality protections. A $20-per-month subscription does not buy you privilege.

Pre-existing documents cannot be retroactively cloaked in privilege. The AI-generated documents were created by Heppner before he transmitted them to counsel. Sending these unprivileged materials to his lawyers after the fact did not retroactively make them privileged.

Implications for waiver of privilege

Heppner fed information he had received from his attorneys into Claude. The government argued, and Judge Rakoff agreed, that sharing privileged communications with a third-party AI platform may constitute a waiver of the privilege over the original attorney-client communications themselves. The privilege belongs to the client, but so does the responsibility to maintain it."

"Privacy policies, including the one on Claude's website, openly inform users how their data is used. However, very few users actually read the fine print on these privacy policies, or even know these policies exist in the first place. It would probably surprise most people to learn that Claude's privacy policy explicitly gives its parent company, Anthropic, the right to disclose a user's data to third parties in connection with legal disputes and litigation."
