A recent Delaware Supreme Court decision provides a lesson for drafters of agreements for the sale of a business by providing an example of the problems caused by a lack of clarity in describing a deadline to send notices of claims for indemnification post-closing. To paraphrase a former member of the U.S. Supreme Court, the Delaware Supreme Court is always right when it comes to deciding Delaware law not because the members of the Court are infallible, but rather because they always have the last word.  The reader can decide how that aphorism applies to the decision of a divided court in the matter of North American Leasing v. NASDI Holdings, Del. Supr., No. 192, 2020 (April 11, 2022).
