Charles Evans Hughes, Shields v. Utah Idaho Central Railroad Company…
“ Nor is there ground for holding that the Commission in reaching its determination departed from applicable principles of law. There is no principle of law which required such a carrier to be classified as an interurban railway. Failing in its effort to obtain a clarifying definition from Congress, the Commission performed its duty in weighing the evidence and reaching its conclusion in the light of the dominant characteristics of respondent's operations which were fairly comparable to those of standard steam railroads. ”
