Richter v. Village of Oak Brook 

Firefighter filed several workers' compensation claims, which he settled with Village, relating to shoulder, neck, and back injuries and diesel-induced rhinitis, related to his job. Pension Board awarded firefighter a line-of-duty disability pension, and he then sued Village to have his health insurance premiums paid under Public Safety Employee Benefits Act. After bench trial, court found in favor of Village. Commission's order, which was based on agreed facts, has preclusive effect and thus was a final adjudication on the merits. Collateral estoppel applies only to causation, which was resolved by Commission's entry of settlement contract. Thus, Village was collaterally estopped from relitigating findings in Commission's orders. (McLAREN and HUDSON, concurring.)
