Stanley Forman Reed,
United States v. Public Utilities Commission of California…
“ There, however, the problem was whether the sales of electricity were in 'interstate commerce.' Here, it is a different one whether the entire sale is a 'sale for resale.' For purposes of this case, we need not decide the question of whether a somewhat similar 'commingling'-of power resold with that consumed directly by the purchaser-requires entire federal jurisdiction. For, even assuming arguendo respondents' proposition that it may be proportionally limited, we hold that the record before us in this case does not present a set of facts or findings justifying that result. ”
