For your reading pleasure this morning: Kenneth Adams, "Bamboozled by a Comma: The Second Circuit’s Misdiagnosis of Ambiguity in American International Group, Inc. v. Bank of America Corp.", 16 Scribes J. Legal Writing 45 (2014–15):
In its opinion in American International Group, Inc. v. Bank of America Corp., the United States Court of Appeals for the Second Circuit invoked the principle of construction that this article refers to as “the comma test under the rule of the last antecedent”: if in a sentence a series of nouns, noun phrases, or clauses is followed by a modifier and the modifier is preceded by a comma, the modifier applies to the entire series, not just the final element in the series.
But as the opinion inadvertently demonstrates, that principle of construction is inconsistent with English usage and should be rejected. The opinion also serves as a reminder that judges cannot always be counted on to understand how ambiguity operates; courts should permit expert-witness testimony on ambiguity.
