Headnotes

  1. Constitutional Law — Commerce Clause The power to regulate interstate commerce is the power to prescribe the rule by which the commerce is to be governed — that is, to control the means by which it is carried on — and is not a general authority to forbid the movement of ordinary commodities. 247 U.S. 251, 268-269
  2. Constitutional Law — Commerce Clause Congressional power to prohibit the movement of particular articles in interstate commerce has been sustained only where the character of the particular subjects dealt with, and the scope of governmental authority over them, is such that the authority to prohibit is merely an exertion of the power to regulate — as where the use of interstate transportation is necessary to accomplish a harmful result. 247 U.S. 251, 268-270
  3. Constitutional Law — Commerce Clause The manufacture and mining of goods are not commerce, and the fact that the goods are intended for later shipment in interstate commerce does not make their production a part of that commerce or subject it to congressional control; production of articles intended for interstate commerce is a matter of local regulation. 247 U.S. 251, 272
  4. Constitutional Law — Commerce Clause When interstate commerce begins is determined not by the character of the commodity, the owner's intention to transfer it to another state, or his preparation for transportation, but by its actual delivery to a common carrier or the actual commencement of its transfer to another state. 247 U.S. 251, 272 (citing In re Green, 52 F. 113)
  5. Constitutional Law — Commerce Clause The Commerce Clause does not confer on Congress a general authority to equalize economic conditions among the States or to prevent possible unfair competition by forbidding the interstate transportation of goods produced under conditions Congress deems unfair. 247 U.S. 251, 273
  6. Constitutional Law — Tenth Amendment The grant of power to Congress over interstate commerce was not intended to give it authority to control the States in the exercise of their police power over local trade and manufacture, a power always existing and expressly reserved to the States by the Tenth Amendment. 247 U.S. 251, 273-274
  7. Constitutional Law — Commerce Clause A federal statute prohibiting the interstate shipment of goods produced in factories or mines employing children within specified ages and hours exceeds Congress's authority under the Commerce Clause, because its necessary effect is to regulate the hours and conditions of child labor within the States — a purely local matter reserved to state authority. 247 U.S. 251, 276-277
