New York passed the Milk Control Act which prohibited the sale of milk imported from another state by third parties unless the price paid to the producer in the other state reached at least the minimum amount required to be paid to local New York milk producers. G.A.F. Seelig, Inc. (plaintiff), a Vermont milk producer, brought suit in federal district court against Baldwin (defendant), a New York state official, challenging the Milk Control Act as an unconstitutional burden on interstate commerce. The district court granted partial relief for G.A.F. Seelig, Inc. regarding its milk imported in original cans and bottled in New York, but denied relief for milk imported from Vermont in bottles. Both parties appealed to the United States Supreme Court.
