8 N.W.3d 501
Iowa2024Background
- The Vagts family operates a longstanding dairy farm in West Union, Iowa; Northern Natural Gas Company (NNG) runs a federally regulated natural gas pipeline with a cathodic protection system under their land.
- From 2013 onward, the Vagts experienced severe health and behavior issues with their dairy herd, including increased deaths, which they eventually attributed to stray electrical voltage from NNG's system.
- The Vagts sued NNG for nuisance (after dismissing their negligence claim) and, after a jury trial, were awarded $4.75 million in damages.
- NNG appealed, arguing the trial court erred by failing to require proof of negligence for the nuisance claim and by not reducing what it considered excessive damages.
- The district court and Iowa Supreme Court applied longstanding Iowa nuisance law, which does not require negligence as an element, and upheld the jury’s verdict and damages.
Issues
| Issue | Plaintiff's (Vagts) Argument | Defendant's (NNG) Argument | Held |
|---|---|---|---|
| Is negligence an element of a nuisance claim? | Nuisance does not require proof of negligence, only that the nuisance exists and causes significant unreasonableness and harm. | Negligence (or fault) should be required; otherwise, only inherently dangerous activities can be strict-liability nuisances. | Court held negligence is not required for a nuisance claim under Iowa law. |
| Was it error to deny NNG's jury instruction on negligence? | Court’s jury instructions matched Iowa nuisance law—no negligence required. | Requested jury be instructed on negligence and comparative fault principles. | Court affirmed lower court’s instruction excluding negligence. |
| Was the damages award excessive or unjustified? | Suffering and inconvenience from the nuisance are compensable special damages. | Award for personal inconvenience and non-economic harm lacked evidentiary support and was excessive. | Court found factual support and deferred to jury’s assessment of damages, upholding the award. |
| Should comparative fault/limits apply as with electric utilities? | Comparative fault statute does not apply to non-electric utilities. | Sought similar limits as those legislatively provided to electric utilities. | Court did not extend comparative fault defense to NNG; statute only covers electric utilities. |
