You’ve probably seen clever musings about the need for commas. “Let’s eat, Grandma!” versus “let’s eat Grandma” goes from joyful to dreadful, all for want of a lowly comma.

In O’Connor v. Oakhurst Dairy, the lowly comma brought down a giant. Maine’s overtime statute says that the employer doesn’t have to pay overtime for people whose jobs involve “the canning, processing, preserving, freezing, drying, marketing, storing, packing for shipment or distribution of: (1) agricultural produce; (2) meat and fish products; and (3) perishable foods” (emphasis added). In comes Mr. O’Connor, whose job involves driving a truck, i.e. distribution. When he didn’t get paid overtime, he sued. His legal argument, in so many words, was “I don’t do packing for shipment, nor do I do packing for distribution. I just do the distribution without doing any packing at all.” And the Court agreed.
