What the court wrote
Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.
Kumar Magistrate Judge Curtis Ivy, Jr. ORDER TO SHOW CAUSE Counsel for plaintiff, Ronnie E. Cromer, Jr. (“Cromer”) filed a response brief containing multiple citations that were entirely fictitious, had different citations, and/or did not contain the quote or content attributed to them. See ECF No. 50. Cromer admitted at a hearing before the Court on March 12, 2025, that he used a generative artificial intelligence engine (AI) to draft that brief, that AI supplied the bogus case law cited, and that he did not review or cite check that case law before filing his brief. Due to Cromer’s negligent conduct in this case, the Court ordered him to attend the ethics seminar offered by the State Bar of Michigan on April 8, 2025, Case 4:21-cv-12589-SDK-CI ECF No. 73, PageID.
