Michie (P) and thirty-six other Canadians filed a federal diversity nuisance suit against three American corporations. One of the three corporations was D. Each plaintiff claimed between $11,000 to $35,000 in individual damages resulting from pollution discharged into the air by the three corporations. The injuries sustained from the plants of the three corporations were indivisible. D moved to have the complaint dismissed because each plaintiff failed to meet the $10,000 federal diversity requirement. The trial court denied that motion. D appealed.
