Tom C. Clark,
Phillips Petroleum Company v. Wisconsin…
“ The Federal Power Commission is thereby thrust into the regulatory domain traditionally reserved to the states.The natural gas industry, like ancient Gaul, is divided into three parts. These parts are production and gathering, interstate transmission by pipeline, and distribution to consumers by local distribution companies. A business unit may perform more than one of these functions-typically, production and gathering in addition to interstate transmission. But Phillips' natural gas operations are confined exclusively to the first part-production and gathering. ”
