Veterans are among the most vocal opponents of the measure passed on a party line 55-38 vote Thursday. The bill now heads to Gov. Scott Walker.
The heavily lobbied proposal would require plaintiffs who have suffered from asbestos exposure to reveal how many businesses their attorneys plan to sue. They would also have to go after money from an asbestos trust before they could sue for more in court.
Proponents argue it is needed to prevent filing multiple claims against both trust funds set up to pay victims of asbestos exposure as well as individual businesses.
Democrats argue the changes would make it more difficult for people harmed by asbestos to collect damages.
