What the court wrote
Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.
This cannot be undertaken at too broad a level of generality, id., and it certainly cannot be established by citation to nonexistent cases. Here, Plaintiffs make a borderline sanctionable attempt to identify “clearly established” law from five cases. ECF No. 18. Three of these cases—Iko v. Shreve, 122 F.3d 707 (4th Cir. 1997), Yates v. Terry, 817 F.3d 877 (4th Cir. 2016), and Dawkins v. Fields 354 F.3d 392 (5th Cir. 2003)—are either non-existent or mistakenly out-of-circuit and, in any event, inapposite. With respect to Dawkins, this Court cannot even find a case purporting to “clearly establish” law on the matter and wastes its limited judicial resources in doing so. ... The Court cautions that use of generative artificial intelligence that results in repeated misrepresentations of law may qualify for sanctions under Fed. R. Civ. P. 11(b)–(c).
