concurring. I concur in the conclusion here that the Public Utilities Commission did not abuse its discretion in its determination made under the law existing at the time of the order of the commission. However, I wish to emphasize that such an order of the commission, or this affirmance by this court, would no longer be the law subsequent to the effective date of Am. Sub. H. B. No. 406, as set forth in footnote 3 herein.
