Owen J. Roberts, Western Distributing Company v…
“ The opportunity exists for one member of the combination to charge the other an unreasonable rate for the gas furnished, and thus to make such unfair charge in part the basis of the retail rate. The state authority whose powers are invoked to fix a reasonable rate is certainly entitled to be informed whether advantage has been taken of the situation to put an unreasonable burden upon the distributing company, and the mere fact that the charge is made for an interstate service does not constrain the commission to desist from all inquiry as to its fairness. ”
