Yazoo & Mississippi Valley Railroad Company v. Greenwood Grocery Company‪.‬

The Grocery Company was permitted in the state courts to offset against a claim for demurrage, its claim against the Railroad Company for penalties aggregating $58 for delays in delivering cars to the Grocery Company, the consignee thereof, at the completion of interstate transportation, the right to which penalties arose from certain rules of the Railroad Commission of Mississippi copied in the margin. Eighteen dollars of the penalties accrued after June 29, 1906, the date of the passage of the Hepburn Act.
