Senate Bill 328, as amended, makes significant changes to the law governing jurisdiction in Illinois, which would change Illinois from a specific jurisdiction state to a general jurisdiction state for actions that allege injury or illness resulting from exposure to a toxic substance. Per the Uniform Hazardous Substances Act of Illinois, “toxic” is defined as “any substance (other than radioactive substance) which has the capacity to produce bodily injury or illness to man through ingestion, inhalation, or absorption through any body surface.” Senate Bill 328, with end of session amendments, passed both chambers as of June 1, 2025. Governor JB Pritzker is expected to sign the legislation into law.
