    Case History

    Recent Major Case Experience
    • Represented Mitsubishi Heavy Industries America in the recently concluded lawsuit in Milwaukee County Circuit Court relating to the construction of the radial retractable roof of Miller Park (the home of the Milwaukee Brewers). The case, filed by the Southeast Wisconsin Professional Baseball Park District, sought $50 million in damages from Mitsubishi for alleged defects in the retractable roof, which Mitsubishi constructed. Mitsubishi denied liability and filed a counterclaim seeking additional costs incurred in constructing the roof due to material changes made to the roof's design by the Baseball Park District's architect-of-record after Mitsubishi bid the job. In late 2004, following three years of contentious litigation, the parties attempted mediation. After three days of mediation involving 22 attorneys from seven states, a settlement was reached in January 2005, resulting in Mitsubishi paying nothing on the Baseball Park District’s claims and receiving $18 million on its counterclaim.
    Recent Major Case Experience (Part 2)
    • Also represented Mitsubishi, post verdict and on appeal, in connection with the insurance issues presented in the ironworker death cases likewise brought in Milwaukee County Circuit Court arising out of the construction of Miller Park. These consolidated cases (which gave rise to a trial court verdict of $99M in December 2000) and the multiple consolidated appeals that were pending before the Wisconsin Court of Appeals—raising both trial error and insurance issues—were all recently settled and the appeals dismissed effective as of February 2006. Mitsubishi itself paid nothing, and the trial court rulings in favor of Mitsubishi on all issues of insurance coverage remained in force for Mitsubishi's benefit.
