Generally revise asbestos litigation laws

This bill revises Montana's asbestos litigation laws by requiring individuals filing asbestos lawsuits to disclose all related compensation claims they have made against asbestos trusts within 30 days of filing. It establishes transparency rules that mandate claimants provide sworn statements confirming they have completed all applicable trust claims and submit all related documents, including medical records and settlement information. The legislation also allows defendants to request additional trust claims before trial and permits courts to delay proceedings if claimants fail to comply with disclosure requirements. Additionally, the bill makes trust claim materials and governance documents presumptively admissible in court, removing protections against discovery for these documents. These changes directly affect people filing asbestos-related lawsuits and the defendants in those cases by creating stricter disclosure and discovery procedures.
