remove any commissioner for inefficiency,
neglect of duty or malfeasance in office. Authority is given to the
commission to inquire into the management of the business of all common
carriers subject to the provisions of the act and to require the
attendance of witnesses and to invoke the aid of any court of the United
States for that purpose.

Section 13 authorizes any person, firm, corporation or association, any
mercantile, agricultural or manufacturing society, any body politic or
municipal organization to file complaints against any common carrier
subject to the provisions of the act, with the commission, whose duty it
is made to forward a statement of the charges to such common carrier and
call upon him to satisfy the complaint or answer the same in writing,
and to investigate the matters complained of, if the complaint is not
satisfied. The commission is also charged with the duty of making such
investigations at the request of State or territorial railroad
commissions and may even institute them at its own motion. Section 14
requires the commission to make a report in writing of any investigation
it may make and to enter it of record and furnish copies of it to the
complainant and the common carrier complained of. Section 15 makes it
the commissioners' duty, when it is found that any law cognizable by it
has been violated by a common carrier, to serve notice on such carrier
to desist from such violation and to make reparation for an injury found
to have been done. If any lawful order or requirement of the commission
is disobeyed by a common carrier, it becomes their duty and is lawful
for any company or person interested in such order to apply by petition
to the Circuit Court of the United States sitting in equity in the
judicial district in which the common carrier complained of has its
principal office, and the court has power to hear and determine the
matter speedily and without the formal pleadings and proceedings
applicable to ordinary suits, and to restrain the common carrier from
continuing such violation or disobedience. It is further provided by
this section that on such hearings the report of the commission shall be
accepted as _prima facie_ evidence.

Section 17 regulates the proceedings of the commission. A majority
constitute a quorum for the transaction of business. The commission may
from time to time make or amend rules for the regulation of proceedings
before it. Any party may appear before it
