Joseph McKenna, West v. Kansas Natural Gas Company…
“ If the power over highways and eminent domain be as absolute as asserted, it will have to be given effect, no matter for what purpose exercised. We are therefore admonished at the very start in the discussion of the importance of the questions presented and the power which the states may exert against one another, even accepting the concession of appellant that Congress may break down the isolation by granting the right not only to take private property, but to subject the highways of the state, against the consent of the state, to the uses of interstate commerce. ”
