The Eleventh Circuit certified a question to the Georgia Supreme Court, asking whether property damage can constitute an "occurrence" under a CGL policy where its effects are not felt on "other property." HDI-Gerling Am. Ins. Co. v. Morrison Homes, Inc., 2012 U.S. App. Ct. LEXIS 23813 (11th Cir. Nov. 19, 2012).

The general contractor, Taylor Morrison Services, Inc., was covered by a CGL policy issued by Gerling. The policy excluded "expected or intended injury," contractual liability," and business risk exclusions. Morrison was sued by homeowners in a class action suit. Morrison had allegedly omitted four inches of gravel required beneath the base of the concrete foundations by the Uniform Building Code. Thereafter, the houses sustained water intrusion, cracks in the floors and driveways, and warped and buckling flooring.

Gerling defended, but sued Morrison for a declaratory judgment.
