This bill seeks to prohibit civil liability actions against manufacturers and sellers of stone slab products for injuries, such as silicosis, that result from the alteration or fabrication of these products by third parties. It specifically targets "qualified civil actions" where harm arises from occupational exposure to crystalline silica or other substances generated during the cutting, drilling, or grinding of products like quartz or mineral slabs. The legislation asserts that these products are not inherently dangerous when manufactured, and injuries typically stem from third-party fabricators who may fail to adhere to federal and state workplace safety regulations. Manufacturers and sellers, who lack control over these independent fabricators, are deemed not responsible for such alleged injuries. Consequently, the bill mandates the dismissal of all pending qualified civil actions in both Federal and State courts. The measure aims to protect these businesses from what are considered frivolous lawsuits, preserve the industry, and prevent undue burdens on interstate commerce. It clarifies that this prohibition does not apply to cases where the manufacturer or seller was the direct employer of the injured party, focusing solely on liability for the actions of independent third-party fabricators.
