opinion: Per Curiam.
  In these cases Oklahoma has attempted to fix a minimum price to be paid for natural gas, after its production and gathering has ended, by a company which transports the gas for resale in interstate commerce. We held in Phillips Petroleum Co. v. Wisconsin, 347 U. S. 672, that such a sale and transportation cannot be regulated by a State but are subject to the exclusive regulation of the Federal Power Commission. The Phillips case, therefore, controls this one.
  We disagree with the contention of the appellees that Cities Service Gas Co. v. Peerless Oil and Gas Co., 340 U. S. 179, and Phillips Petroleum Co. v. Oklahoma, 340 U. S. 190, are applicable here. In those cases we were dealing with constitutional questions and not the construction of the Natural Gas Act. The latter question was specifically not passed upon in those cases.
  Reversed.
