[198] 169 U.S. 466 (1898).—Of course the validity of rates prescribed by a State for services wholly within its limits, must be determined wholly without reference to the interstate business done by a public utility. Domestic business should not be made to bear the losses on interstate business, and vice versa. Thus a State has no power to require the hauling of logs at a loss or at rates that are unreasonable, even if a railroad receives adequate revenues from the intrastate long haul and the interstate lumber haul taken together. On the other hand, in determining whether intrastate passenger railway rates are confiscatory, all parts of the system within the State (including sleeping, parlor, and dining cars) should be embraced in the computation; and the unremunerative parts should not be excluded because built primarily for interstate traffic or not required to supply local transportation needs.—See: Minnesota Rate Cases (Simpson v. Shepard), 230 U.S. 352, 434-435 (1913); Chicago, M. & St. P.R. Co. v. Public Utilities Commission, 274 U.S. 344 (1927); Groesbeck v. Duluth, S.S. & A.R. Co., 250 U.S. 607 (1919). The maxim that a legislature cannot delegate legislative power is qualified to permit creation of administrative boards to apply to the myriad details of rate schedules the regulatory police power of the State. To prevent the conferring upon an administrative agency of authority to fix rates for public service from being a mere delegation of legislative power, and therefore void, the legislature must enjoin upon it a certain course of procedure and certain rules of decision in the performance of its functions, with which the agency must substantially comply to validate its action.
