A related doctrine is the insurance law doctrine of efficient proximate cause. Under this rule, in order to determine whether a loss resulted from a cause covered under an insurance policy, a court looks for the predominant cause which sets into motion the chain of events producing the loss, which may not necessarily be the last event that immediately preceded the loss. Many insurers have attempted to contract around efficient proximate cause through the use of "anti-concurrent causation" (ACC) clauses, under which if a covered cause and a noncovered cause join together to cause a loss, the loss is not covered. A minority of jurisdictions have ruled ACC clauses to be unenforceable as against public policy, but they are generally enforceable elsewhere.

Famous quotes containing the word efficient:
“The truly efficient laborer will not crowd his day with work, but will saunter to his task, surrounded by a wide halo of ease and leisure, and then do but what he loves best. He is anxious only about the fruitful kernels of time.”
—Henry David Thoreau (1817–1862)
