On a 7-0 vote, the Louisiana Supreme Court issued a rare peremptory writ, reversing the Third Circuit Court of Appeal and reinstating the district court’s exception of venue, dismissing a suit against U.S. Mineral Products Company for its alleged participation in an industry-wide conspiracy to suppress information about the harmful properties of its insulation product. The peremptory writ affirmed the law in Louisiana that product manufacturers are not liable for property damages caused by the products made by others and clarified the application of solidarity liability to manufacturers of different products.
