United States ex rel. Solano v. Barton Associates, Inc.

How did the court address the AI-related conduct?

In an opinion by Judge Rikelman, the First Circuit affirmed the district court's rulings, "[d]iscerning no legal error or abuse of discretion." It agreed that the relators' complaint did not plead fraud with the particularity Rule 9(b) requires, that the district court acted within its discretion in denying leave to amend a request the court described as a "boilerplate entreaty," and that there was no "manifest abuse of discretion" in denying reconsideration under Rule 59(e). The court recorded the misrepresented holdings and the quotations it could not find, and noted that the reply brief repeated the problems after the appellee identified them, but it imposed no sanction, issued no order to show cause, and made no referral. The opinion does not mention artificial intelligence and does not attribute the defective quotations to any tool or to any individual attorney.

Why does United States ex rel. Solano v. Barton Associates, Inc. matter for law firms using AI?

The First Circuit decided this False Claims Act appeal on ordinary grounds: the relators did not plead fraud with the particularity Rule 9(b) requires, their request to amend was a “boilerplate entreaty,” and their reconsideration motion made conclusory assertions that did “no more than reiterate” earlier arguments. The court’s statements about the briefs appear alongside that analysis rather than in a separate section, and it did not open any sanctions process.

What the court did say is direct. It described the relators’ account of First Circuit law on leave to amend as a misrepresentation (“But we have never so held”), made the same point about their Rule 59(e) argument (“None of the cases they cite stand for such a proposition”), and in footnote 4 stated that the opening brief “referenced quotations that do not appear in those cases or in any case that we have been able to find.” The footnote also records that the problems continued in the reply brief “even after Barton pointed out these errors.”

The opinion does not mention artificial intelligence, does not identify the defective quotations, and does not attribute them to any individual lawyer. Its significance for firms is the record it creates: a circuit opinion that describes a party’s briefs as misrepresenting precedent and quoting language not found in any case the court could locate. Firms documenting compliance may wish to consider how their review of a reply brief responds when the opposing brief has already flagged citation problems.
