During an ongoing civil trial involving dealership market allocation disputes, the defendant sought permission to rely on a second supplemental expert report and to introduce maps and charts derived from previously discovered market study data.
The plaintiff argued the late expert report constituted trial by ambush and violated prior scheduling orders.
The court held that the supplemental expert opinion properly responded to new expert evidence and newly discovered data introduced during the proceedings, and its admission would not cause unfair prejudice.
The court also permitted the introduction of charts and maps derived from historical data for explanatory purposes, while refusing to authorize a new expert report from a non-designated witness responding to the opposing expert.
