THE SIGNAL
On September 3, 2026, the District of Columbia Court of Appeals issued a published order in Douglas v. Deutsche Bank National Trust Co., No. 24-CV-1099, striking the appellee's brief. Four of the authorities it cited did not exist. The attorney who submitted it told the court she had used a generative AI search tool to help locate case authority and had not verified the citations before filing.
The court said its "intent is not to discourage attorneys from using AI." Its problem was the missing check: "Had any of the firm's attorneys reviewed the brief prior to filing, they would have discovered the errors." It added that "every firm attorney who signed the brief bears some responsibility," rejected the firm's suggestion to accept the brief with the bad citations redacted, and referred the matter to the Office of Disciplinary Counsel.
A concurring opinion observed that striking a brief "penalizes the innocent client for its counsel's offense." It pointed to practical measures: clear firm policies on AI use, requiring attorneys to confirm they have complied with those policies, and pre-filing citation vetting, which it said can be done cost-effectively by a trained paralegal.
BEFORE
Hypothetical: a litigation team is filing an appellate brief by 11:59 p.m. An associate drafted it with help from a research tool. At 6 p.m. the paralegal's cite check comes back: two citations cannot be located, and one quotation does not match the opinion it cites.
There are three ways forward: cut the argument, rebuild it on real authority, or ask for an extension. Only the partner whose name goes on the brief can make that call. She is in a deposition until 8 p.m. and then on a flight.
The file is ready. The person who can release it is not.
WHAT THE WAIT COSTS
Late at night, someone files what they have, or deletes the flagged citations without rethinking the argument that depended on them. If a bad citation goes in, the cost can land on the client, as the D.C. court noted, and on every lawyer named on the brief. If the team waits too long, the deadline passes.
AFTER
The cite check produces a decision packet instead of an email thread: each flagged authority, what the brief says it holds, what the source actually says, the paragraphs that depend on it, and the associate's proposed fix.
The signing partner reviews the packet between sessions. She approves two fixes, cuts one argument, and confirms the firm's AI policy check is complete. The brief is filed hours before the deadline, and the record shows who verified each citation and who released the filing.
HOW WISDOMTWIN FITS
WisdomTwin.ai is building a sovereign judgment layer for regulated enterprises. It is designed to give each named approver a role-specific judgment twin that prepares the decision packet the way that person reviews, with the evidence attached, so the decision moves faster and leaves an auditable record. It is designed to run on-premises, on-device or in your private cloud, and the named person still makes the call.
We don't replace judgment. We remove the wait.
TRY THIS THIS WEEK
For your next three filings, write down who runs the cite check and how many hours before the deadline it is due.
Name the attorney who decides what happens to a flagged citation, and a backup for when that person is unavailable.
List what that attorney needs to see to rule on a flag in one sitting: the citation, the claimed holding, the source text and the proposed fix.
