Baldwin v. G.A.F. Seelig, Inc.

New York's Milk Control Act barred the in-state sale of milk imported from another state unless the price paid to the out-of-state producer was at least the minimum New York producers would receive. G.A.F. Seelig, Inc. (plaintiff), a Vermont milk dealer, sued New York official Baldwin (defendant) in federal court, arguing the Act unconstitutionally burdened interstate commerce. The district court granted partial relief, and both sides appealed.

Whether a state may impose restrictions burdening interstate commerce for the purpose of reducing competition between the states under the Commerce Clause.
