The Supreme Court of Nevada held that even if an insured's noncompliance with an exclusion is not causally related to a loss, the exclusion may apply if it is unambiguous, narrowly tailored, and essential to the risk undertaken. The case is Griffin v. Old Republic Ins. Co., No. 44902, 2006 WL 1278704 (Nev. May 11, 2006).

A plane owned and operated by Kevin Jensen crashed in Robert Griffin's backyard, causing severe personal injuries to Griffin . Jensen was insured under an aviation policy issued by Old Republic . Old Republic claimed it had no obligation to pay for Griffin 's damages because Jensen did not possess an in-force airworthiness certificate at the time of the crash.
