Civil cause of action for trespass of intangible particulate matter created.

Minnesota House Bill HF4363, introduced on March 16, 2026, aims to establish a legal right for individuals to sue if intangible particulate matter, such as dust or smoke, from another property enters their property without permission. This bill would allow property owners to seek damages in court for such intrusions.

Supporters of HF4363 argue that it empowers property owners to protect their land and health from pollution caused by neighboring properties. Environmental advocates see it as a step toward holding polluters accountable and promoting cleaner air.

Critics of HF4363 express concern that it could lead to an increase in lawsuits, potentially burdening the legal system and creating conflicts between neighbors. Some industry representatives worry that it might impose additional operational challenges and costs on businesses that emit particulate matter as part of their processes.
