Felix Frankfurter

“ While I join the opinion of the Court, one consideration leading to the Court's conclusion is for me so decisive that I deem it appropriate to give it emphasis.
Section 1 (b) is not to be construed on its face. It comes to us with an authoritative gloss. ”

“ Kansas (Natural) Gas Co., 265 U.S. 298 (44 S.Ct. 544) , and Public Utilities Commission v. Attleboro Steam & Electric Co., 273 U.S. 83 (47 S.Ct. 294) ) the basic purpose of the legislation is to occupy this field in which the States may not act.'
The section must be read with such an interpolation because the committees of Congress which were responsible for the legislation said specifically that the Natural Gas Act was designed to cover the situations which the two cited cases held to be outside the competence of State regulation. ”
