In yet another of the collapse cases being litigated in state and federal courts in Connecticut, the federal district court denied the insurer's motion to dismiss. Rosenberger v. Amica Mut. Ins. Co., 2018 U.S. Dist. LEXIS 95345 (D. Conn. June 6, 2018).

The insureds had policies with Amica since 1989. Policies before December 18, 2006, covered collapse caused by hidden decay or other specified causes. "Collapse" was not defined by the policy. These policies did not include any provisions explicitly excluding coverage for a chemical reaction.

The post-2006 policies held by the insureds covered collapse, but under a significantly modified definition. The newer policy language stated that "collapse applies only to an abrupt collapse." Further, collapse was defined as "an abrupt falling down or caving in of a building or any part of a building with the result that the building or part of the building cannot be occupied for its intended purpose."
