Justice Cardozo agreed that the Petroleum Code quota dispute did not warrant adjudication, because the supposedly enforceable quota provision had been removed and no existing mandate put the petitioners in jeopardy. He dissented, however, from invalidating § 9(c) and the hot-oil prohibition.
In his view, § 9(c) did not give the President a roving power over all interstate commerce. Congress confined the authority to one commodity—oil produced above valid state limits—and prescribed the sole means available to the President: prohibiting its interstate transportation. The remaining question was when that limited authority could be used.
Cardozo read § 1’s declaration of national-recovery policy as an implied but sufficient standard. The President could act when, in light of conditions in the oil industry, excluding hot oil would advance Congress’s stated goals, including eliminating unfair competition, conserving natural resources, preventing destructive overproduction, stabilizing prices, and relieving unemployment.
Transporting illegally produced oil, Cardozo reasoned, forced lawful producers to compete with lawbreakers and could undermine state conservation regimes. Congress could not know in advance whether violations of state quotas would become sufficiently widespread or economically damaging to require a federal interstate-commerce prohibition. It could therefore leave the President to ascertain changing industrial facts and decide whether the statutory remedy would serve the declared national policy.
Cardozo also rejected the majority’s conclusion that the executive order required express factual findings. Neither the Constitution nor § 9(c) required the President to recite his reasons. Absent a showing that the order was arbitrary or bore no conceivable rational relation to the statute’s policies, the President’s official action should be presumed to rest on an adequate inquiry and proper grounds.
