What the court wrote

Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.

For this reason, the Court need not reach the other dismissal arguments made, including those regarding service. A Caution on AI Hallucinations As a postscript to these motions, the Court must address certain AI-generated hallucinations in Petitioners’ papers. After the fake citations were pointed out in the reply papers, Petitioners’ counsel wrote a letter to the Court acknowledging the false citations, withdrawing them, and apologizing. At oral argument held on these motions, counsel reiterated the apology, acknowledged that the use of AI without proper checking was wrong, and identified the specific ways that steps were being taken by him and his firm to prevent future problems. While the Court does not deem it necessary to issue sanctions here, it does wish to issue a warning about the use of AI in preparing court documents.
