William O. Douglas,
Schwegmann Bros v. Calvert Distillers Corp…
“ The State acts are in no sense general price-fixing acts. They merely authorize a manufacturer or producer to enter into contracts for the maintenance of his price, but they do not compel him to do so. In other words, they are merely permissive.They do not authorize horizontal contracts, that is to say, contracts or agreements between manufacturers, between producers, or between wholesalers, or between retailers as to the sale or resale price of any commodity. ”
