Federal Trade Commission v. Ruberoid Company/Concurrence Black
Mr. Justice BLACK concurs in the judgment and opinion of the Court, except that he thinks the Commission's order should expressly except from its prohibitions differentials which merely make allowances for differences in the cost of manufacture, sale, or delivery, or which are made in good faith to meet an equally low price of a competitor.

Mr. Justice FRANKFURTER, not having heard the argument, owing to illness, took no part in the disposition of this case.

Mr. Justice DOUGLAS dissents from the denial of enforcement of the order.

Mr. Justice JACKSON, dissenting in No. 504.
