What the court wrote
Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.
Our review of father’s brief shows that it contains many citations to caselaw that either do not exist—sometimes referred to as “hallucinations”—or do not support his legal argument. And father’s brief inaccurately quotes statutes and the record. Our review also leads us to believe that father may have used generative artificial intelligence (AI) to write his brief. While AI can be a helpful tool and we do not suggest that court rules prohibit its use,weemphasizethat hallucinatedcaselawisnotvalidauthorityandthatallpartiesshould be mindful of the importance of accuracy in their submissions. Finally, as discussed below, father fails to cite authority that supports his position and to articulate an argument in support of some issues. This results in forfeiture, and the issue “will not be considered on appeal unless prejudicial error is obvious on mere inspection.” Schoepkev.AlexanderSmith& SonsCarpetCo.,187 N.W.2d133,135 (Minn. 1971). We reorganize the arguments in father’s brief into six issues and discuss each in turn. I.
