§ 118. Investigations by commissioner. 1. The commissioner may, of his
own motion, investigate or make inquiry, in a manner to be determined by
him as to any act or thing done or omitted to be done by any common
carrier, subject to his supervision, and the commissioner must make such
inquiry in regard to any act or thing done or omitted to be done by any
such common carrier in violation of law or an order of the commissioner.

2. Complaints may be made to the commissioner by any person or
corporation aggrieved, by petition or complaint in writing setting forth
any thing or act done or omitted to be done by any common carrier in
violation, or claimed to be in violation, or of the terms and conditions
of its franchise or charter or of any order of the commissioner. Upon
the presentation of such a complaint the commissioner shall cause a copy
thereof to be forwarded to the person or carrier complained of, which
may be accompanied by an order, directed to such person or carrier,
requiring that the matters complained of be satisfied, or that the
charges be answered in writing within a time to be specified by the
commissioner. If the person or carrier complained of shall make
reparation for any injury alleged and shall cease to commit, or to
permit, the violation of law, franchise or order charged in the
complaint, and shall notify the commissioner of that fact before the
time allowed for answer, the commissioner need take no further action
upon the charges. If, however, the charges contained in such petition be
not thus satisfied, and it shall appear to the commissioner that there
are reasonable grounds therefor, he shall investigate such charges in
such manner and by such means as he shall deem proper, and take such
action within his powers as the facts justify.

3. Whenever the commissioner shall investigate any matter complained
of by any person or corporation aggrieved by any act or omission of a
common carrier under this section it shall be his duty to make and file
an order either dismissing the petition or complaint or directing the
common carrier complained of to satisfy the cause of complaint in whole
or to the extent which the commissioner may specify and require.
