Understanding the Lamb-Weston Rule: A Guide to Insurance Liability

Definition & Meaning

The Lamb-Weston rule is a legal principle that helps determine how liability is shared between two insurance companies when their policies cover the same risk but contain conflicting clauses. Originating from the case Lamb-Weston, Inc. v. Oregon Auto. Ins. Co., 219 Ore. 129 (Or. 1959), this rule allows courts to disregard mutually contradictory policy clauses. Instead, it prorates liability based on the coverage limits of each policy, providing a straightforward solution to the ambiguities that can arise in insurance agreements.

Real-world examples

Here are a couple of examples of abatement:

(Hypothetical example) Consider two auto insurance policies covering the same vehicle. Policy A states it will cover damages up to $50,000, while Policy B states it will only cover damages if Policy A does not apply. If an accident occurs, the Lamb-Weston rule would allow the insurers to prorate the liability based on their respective coverage limits, rather than leaving the policyholder without coverage due to conflicting terms.
