Harvey published a case study showing GSK Stockmann cut contract review time by up to seventy-five percent on unstructured data rooms. Tasks that once took three to four hours finished in three to four minutes. Then Harvey added a line its own customers should read twice: "Faster output that the lawyer cannot verify is not faster work."
That caveat does more work than Harvey intended. It names the problem every legal AI product has to answer.
The standard assumes you read the document
California's State Bar COPRAC proposed an amendment to Rule 1.1. When lawyers use technology including AI, they "must independently review, verify, and exercise professional judgment regarding any output generated by the technology that is used in connection with representing a client." The standard treats AI output the way firms have always treated a junior associate's draft. Check it and apply your own judgment.
The logic holds when the junior prepared the draft. The senior partner's review took roughly as long as the preparation because the partner read the document. Formed independent views on risk allocation and missing protections. The review was substantive because it was slow. It was slow because reading is slow.
When AI compresses the preparation from days to minutes, economic pressure compresses the review too. The partner skims the summary. Checks the flagged clauses. Signs off. The oversight is formally present and substantively empty.
The agent extension test
The agent extension test asks: can you describe how you think clearly enough that an agent can apply it to a new case and you'd endorse the result? If yes, your thinking is a method. If no, it is a habit dressed as expertise.
Legal contract review should pass this test. Lawyers follow frameworks: identify governing law, then verify representations against known facts. These steps are describable. An agent, human or software, can execute them.
The test has a precondition most people skip. The agent must have access to the same information the principal used to form the judgment. In contract review, that information is the document itself, not a summary or a set of flagged excerpts.
The EDRM put it directly: AI "compresses the path from raw information to apparent understanding so efficiently that the polished output creates an illusion that substantive legal analysis has already occurred ..." when it has not. A lawyer reviewing an AI summary applies judgment to the AI's representation of the contract, not to the contract itself. Different acts. Different failure modes.
The liability closed the escape route
California AB 316, effective January 1, 2026, added Civil Code section 1714.46. It bars defendants from arguing that "the artificial intelligence autonomously caused the harm" as a defense. The lawyer cannot blame the tool.
ABA Formal Opinion 512 established that generative AI tools "lack the ability to understand the meaning of the text they generate or evaluate its context." In Lacey v. State Farm, a federal court in California sanctioned lawyers thirty-one thousand dollars after nine of twenty-seven citations were wrong or fabricated. In Couvrette v. Wisnovsky, an Oregon federal court imposed over one hundred and ten thousand dollars for fifteen nonexistent cases and eight fabricated quotations.
Seven of thirteen surveyed carriers now report AI-related claims increases. Solo practitioners account for just over fifty percent of all cases tracked in the Hallucination Database. The lawyer cannot blame the AI. The lawyer also cannot practically read every document the tool processed.
The bind
One practitioner quoted in Minnesota Lawyer captured it: "Is it an effective use of resources for me to have to scrub every line that comes out of a ChatGPT to make sure it doesn't contain a hallucination?" The honest answer is no. It is also required.
An upvoted argument on r/legaltech describes the workflow as uploading the contract, reading the AI summary, then reading the whole contract anyway to verify. If checking the output takes as long as doing the work, the tool saves nothing.
The verification standard assumes the verifier did the reading, and the tool's value proposition is that nobody has to. The agent extension test fails here. Legal reasoning is describable. The test fails because the judgment depends on having read the source material, and reading was the thing the tool replaced.
The profession now faces a choice it has not named. Either the review standard means what it says, and AI contract review saves no time at all. Or the standard quietly lowers to match the tool's economics, and the malpractice gap widens until a carrier prices it in.
