The Brief Looks Finished Before It Is

By Jordan Finneseth

AI can make a legal brief look complete before its cases, quotations, and holdings have been checked. Courts are turning that missing verification into sanctions, fees, and new institutional work.

A court clerk in a law library traces citation threads from a polished stack of filings to open casebooks, with one thread ending at an empty shelf.

A polished filing is only as complete as the source trail behind it. Editorial image.

A legal brief can look complete long before its sources have been checked.

The headings are in place. The cases have official-looking names. Quotes arrive with page numbers. To a person who cannot afford a lawyer or a professional research database, the document may feel like access to a system that used to be locked behind money and training.

A new Arizona Court of Appeals opinion shows what happens when that polished surface enters a court without the judgment layer behind it.

In Dineen, Shibata v. Kotchka, filed July 15, a self-represented appellant acknowledged using artificial intelligence-assisted research. His opening brief contained eight legal citations. The court found six deficient. Two cases did not exist. The other problems included wrong pages, principles the cited cases did not support, misstated rules, and misrepresented facts.

The appellant admitted that he had done no independent verification. The court struck the defective citations. With no valid authority supporting his arguments, it affirmed the underlying probate order. It also awarded the opposing party the portion of reasonable attorneys' fees caused by the hallucinated and misrepresented citations, subject to Arizona's fee-application procedure.

This is a specific Arizona decision applying Arizona law. It does not create a nationwide rule, and it does not make every use of AI in legal work improper.

The court took the access question seriously. Its opinion says generative AI may help self-represented people edit for clarity, summarize large documents, and prepare legal materials. The benefit comes with a hard boundary: the person signing a filing remains responsible for checking the cases, the facts, and the accuracy of what goes into the record.

That duality matters. Cheap drafting can help someone speak in a system built around specialized language. It can also produce confidence faster than competence. A clean-looking filing may transfer the missing work to opposing counsel, clerks, judges, public law libraries, legal-aid staff, and eventually the person who relied on it.

The verification job also goes deeper than confirming that a case exists.

The Sixth Circuit demonstrated that in April in United States v. Farris. An attorney used a commercial legal AI tool and cited genuine cases. Yet the quotations were invented and the holdings were mischaracterized. The court removed the lawyer from the appeal, denied compensation for that appellate work, and referred the matter for further review.

A citation can resolve to a real document and still fail the sentence attached to it. Good review has to inspect the quote, the holding, the procedural posture, the jurisdiction, and whether later law changed the authority. Then a qualified person has to decide whether the source supports the argument being made.

Verification bottleneck

Verification is becoming the scarce institutional function.

  • Legal-looking document production moved faster than affordable systems for checking every source, quotation, holding, fact, and final revision.
  • Filers, lawyers, paralegals, clerks, judges, opposing parties, libraries, and legal-aid programs now absorb the verification work when a draft arrives without a trustworthy trail.
  • Watch next: court-provided verification resources, role-specific sign-off rules, source-attached filings, correction timing, and measurements of how much review work AI-assisted documents create or save.

Opportunities

Where value may appear: a legal citation verification and filing-provenance layer.

A useful system could confirm that an authority exists, retrieve the source text, compare each quotation with the original, and show whether the cited passage supports the proposition in the draft. It could flag a real case used for the wrong holding, preserve the exact version reviewed, record later edits, and name the lawyer or trained reviewer who approved the final filing.

Courts, small firms, clinics, and self-help programs may also need a service that turns those checks into a reviewable audit trail for clerks and lawyers. The software should surface mismatches and missing proof. Legal judgment and responsibility still belong to qualified people operating under the rules that apply to their court and matter.

This is public-interest orientation and builder idea fodder, not legal, compliance, business, financial, or investment advice.

The useful test comes before submission: can another person open the receipt, reach the same source, see the exact passage, and identify who accepted responsibility for the final words? If the answer is unclear, the brief is still unfinished.
