Okla. Stat. tit. 17, § 17-4: Suspension bond

If the order violated for which such fine or judgment is imposed

shall have been an order promulgating or fixing rates, to be charged

by public service corporations, persons or firms, it shall be

necessary in appealing from such fine or judgment for the defendant

to give a suspending bond, executed and filed with and approved by

the Commission, payable to the state, and sufficient in amount and

security to insure the prompt refunding by the appealing

corporation, person or firm, to the parties entitled thereto, of all

charges which such company may collect or receive, pending the

appeal, in excess of those fixed or authorized by the order of the

Commission violated or disregarded by such corporation, person or

firm. Such bond shall be conditioned to require such corporation,

person or firm to keep such accounts and to make to the Commission

from time to time such report, verified by oath, as may in the

judgment of the Commission suffice to show the amount being charged

or received by the company pending the appeal, in excess of the

charge prescribed by the Commission in the order violated, together

with the names and addresses of persons to whom such overcharges

will be refunded in case the charges made by the company pending the

appeal be not sustained on the final judgment, and the commission

may at any time require such corporation, person or firm to give

additional security or to increase the suspending bond when the same

may appear to the Commission to be necessary to insure the prompt

refunding of the overcharges aforesaid. Upon the final judgment, if

the order violated is sustained in the Supreme Court, the Commission

shall distribute such overcharges to the persons to whom the same

are due, as provided in Section twenty-one, Article nine, of the

Constitution: Provided, that if the order violated is one fixing or

establishing rates and the corporation, person or firm shall obey

such order and carry its provisions into effect pending such appeal,

the last above-mentioned bond shall not be required.
