In Amtrust North America, etc. v. Liberty Mutual Insurance Co. , the New Jersey Superior Court Appellate Division said AmTrust North America could proceed with its declaratory judgment action, but only after correcting a key procedural error. The dispute stems from benefits paid to an injured worker, Justin McGinness, who was hurt in a motor vehicle accident while working. AmTrust, the employer’s workers compensation insurer, paid more than $75,000 in benefits and sought reimbursement beyond a $15,000 third-party recovery through underinsured motorist coverage it alleged was issued by the defendants. A trial court dismissed the case with prejudice, finding the insurer sued the wrong parties and lacked a viable subrogation claim. The appellate panel agreed the complaint was deficient because the proper insurer — Ohio Security Insurance — was not named, but said the dismissal should have been without prejudice to allow amendment. The panel declined to reach the substantive coverage and subrogation issues, citing the pleading defects and absence of the relevant policy in the record. Separately, the court imposed a $1,000 sanction on plaintiff’s counsel for citing four nonexistent cases in briefing, calling them “hallmarks” of generative AI and a violation of professional conduct rules requiring candor to the tribunal. “We note plaintiff’s attorney has cited four non-existent cases in his merits brief. When he was made aware of this issue by defendants in their opposition brief, plaintiff’s attorney failed to take any responsibility for his presumed misuse of artificial intelligence (AI) or correct the brief. Counsel did not revise the filed brief or advise the court of the hallucinated case law. Both opposing counsel and this court expended wasted time to research the nonexistent cases,” the ruling states. The court affirmed the dismissal in part, remanded for entry of a dismissal without prejudice and ordered the sanction paid personally by counsel.
