In a declaratory judgment action initiated by an insurer, styled "Liberty Mut. Ins. Co. v. Lone Star Indus. Inc., et al.", No. SC 18199 (Conn. Sup. March 24, 2009), the Connecticut Supreme Court, among other things, agreed with certain insurers of Lone Star, a silica and sand supplier, that a silicosis hazard exclusion endorsement that refers to “silicon,” rather than the chemically distinct “silica,” should be read broadly as applying to silicon in all its forms.
