Section IX-22: Statement of reasons for action - Cause heard on record - Certification of facts and evidence - New or additional evidence.

  The Corporation Commission shall, whenever an appeal is taken
therefrom, file with the record of the case, and as a part
thereof, a written statement of the reasons upon which the action
appealed from was based, and such statement shall be read and
considered by the Supreme Court, upon disposing of the appeal.
In no case of appeal from an order of the Corporation Commission
shall any new or additional evidence be introduced in the Supreme
Court, but the cause shall be heard on the record made before the
Corporation Commission, and the Chairman of the Commission, under
the seal of the Commission, shall certify to the Supreme Court
all the facts upon which the action appealed from was based, and
which may be essential for the prompt decision of the appeal,
together with all evidence introduced before said Corporation
Commission, as may be selected, specified or required to be
certified, by any party in interest, as well as such other
evidence, so introduced before the Commission as the Chairman may
deem proper to certify; provided, however, that in any appeal
from an order of the Corporation Commission in which a party
thereto asserts the violation of any right under the Constitution
of the United States or the Constitution of the State of
Oklahoma, the Supreme Court shall require the Commission to take
and receive such additional evidence as is necessary to
judicially determine the rights of the parties and report the
same to the Court, in such manner as the Court may prescribe, for
its consideration before the appeal is finally decided.
