or act done or omitted to be done by any common carrier or corporation
subject to its supervision, in violation, or claimed to be in violation, of any
provision of law or of the terms and conditions of its franchise or charter,
or of any order of the commission, or as being unfair, unreasonable, un-
justly discriminating or unduly preferential. Upon the presentation of
such a complaint the commission shall cause a copy thereof to be forwarded
to the person or corporation complained of, accompanied by an order,
directed to such person or corporation, requiring that the matter complained
of to be satisfied, or that the charges be answered in writing within a time
to be specified by the commission. If the person or corporation 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 com-
plaint, and shall notify the commission of that before the time allowed
for answer, the commission need take no further action upon the charge.
If, however, the charges contained in such petition be not thus satisfied, and
it shall appear to the commission that there are reasonable grounds therefor,
it shall investigate such charges in such manner and by such means as it
shall deem proper, and take such action within its power as the facts justify.
Whenever the commission shall investigate any matter complained of
by any person or corporation aggrieved by any act or omission of a common
carrier or other corporation subject to the provisions of this sub-title under
this section, it shall be its 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 com-
mission may specify and require.

that the rates, tolls, fares or charges demanded, exacted, charged or col-
lected by any common carrier, railroad or street railroad, railroad corpora-
tion, street railroad corporation, or other corporation subject to the pro-
visions of this sub-title, for the transportation of persons, freight or
property within the State, or that the regulations or practices of such com-
mon carrier or corporation affecting such rates, tolls or services are unjust,
unreasonable, unjustly discriminating or unduly preferential, or in any-
wise in violation of any provision of law, the commission shall determine
the just and reasonable rates, tolls, fares and charges to be thereafter
observed and in force as the maximum to be charged for the service to be
performed, and shall fix the same by order to be served upon all common
carriers or other corporations by whom such rates, fares and charges are
thereafter to be observed. And whenever the commission shall be of the
opinion, after a hearing, had upon its own motion or upon complaint, that
the regulations, practices, equipment, appliances or services of any common
carrier or other such corporation in respect to any services, transportation
of persons, freight or property within this State, are unjust, unreasonable,
unsafe, unreasonably improper or inadequate, the commission shall deter-
mine the just, reasonable, safe, reasonably adequate and proper regulations,
