The Florida Supreme Court of Florida decision in Sebo v. American Home Assurance rejecting the “efficient proximate cause doctrine” in favor of the “concurrent cause doctrine” for property insurance claims represents a significant win for residential and commercial policyholders.

The state’s highest court has determined that the appropriate theory of recovery for claims in which two or more perils contribute to a loss but at least one of the perils is excluded from coverage is the concurrent cause doctrine. Under the rejected efficient proximate cause theory, when multiple perils cause a loss, it is the efficient cause — the one that sets the other in motion — to which the loss is attributed.
