AIU Insurance v. Nationwide Mutual Insurance
The case involves a dispute between two insurers regarding their respective coverage obligations for a mutual insured in an underlying action following a fatal construction site accident. Plaintiff, who insured both the site owner and the subcontractor, sought reimbursement from defendant, who also insured the employer under a workers’ compensation policy, for half of a settlement paid in the underlying action. The Supreme Court initially granted summary judgment to plaintiff, obligating defendant to reimburse plaintiff. However, the appellate court reversed this decision, vacating the judgment and granting summary judgment to defendant. The appellate court ruled that the antisubrogation rule would have compelled the dismissal of any third-party action, thereby precluding plaintiff from obtaining reimbursement from a coinsurer.
