Summary
The Iowa Supreme Court affirmed certification of a class action brought by Muscatine residents against Grain Processing Corporation concerning alleged air pollution from its corn wet milling facility. The court held that common questions of law and fact predominated over individualized issues and rejected the defendant’s due process objections to the proposed classwide proof and damages methodology. The case involved nuisance, trespass, and negligence claims seeking damages for loss of use and enjoyment of property.

Questions Presented
- Whether the district court abused its discretion by finding common questions of law or fact under Iowa Rule of Civil Procedure 1.261.
- Whether common questions predominated over individual questions under Iowa Rule of Civil Procedure 1.263(1)(e).
- Whether class certification and the proposed use of representative evidence and formulaic damages violated Grain Processing Corporation's due process right to litigate individual defenses.
Holdings
- Common questions of law and fact existed within the two subclasses because all class members alleged a common injury arising from Grain Processing Corporation's common course of conduct and emissions from the Muscatine facility.
- Common questions predominated over individual questions because common liability issues concerning Grain Processing Corporation's course of conduct, emissions, knowledge, reasonableness, causation, and the objective nuisance standard were central to the claims, even though damages and some defenses could vary by class member.
- The class-certification order did not violate Grain Processing Corporation's due process rights because the defendant retained the opportunity to contest harm, damages, causation, and individual defenses, and the district court could bifurcate, create additional subclasses, or decertify the class if individualized issues became unmanageable.
- Because nuisance is evaluated under an objective normal-person-in-the-community standard, representative testimony from residents may be used to establish whether the alleged conditions were definitely offensive, seriously annoying, or intolerable throughout the subclasses.

Factual background
Grain Processing Corporation has operated a corn wet milling facility in Muscatine, Iowa, since 1943. Residents living near the facility alleged that smoke, odor, haze, particulate matter, and chemical emissions interfered with their use and enjoyment of property. They limited their requested damages to loss of use and enjoyment of property, excluding diminution-in-value and personal-injury claims, and proposed common evidence concerning the facility's conduct, emissions, objective nuisance-level harm, and a formula for damages.
Procedural history
Eight Muscatine residents filed a putative class action alleging that air pollution from Grain Processing Corporation's corn wet milling plant interfered with the use and enjoyment of their property under nuisance, trespass, negligence, and statutory theories. The district court initially granted Grain Processing Corporation summary judgment based on federal and state-law preemption and the political-question doctrine. In a prior appeal, the Iowa Supreme Court reversed, held the claims were not preempted or barred by the political-question doctrine, and remanded. On remand, the district court certified the class and created close-proximity and peripheral-proximity subclasses. The Iowa Supreme Court affirmed.
