Okla. Stat. tit. 17, § 17-122: Judgment for overcharge - Lien - Collection

Upon ascertaining the amount of overcharge due from any public

service corporation, person or firm, the Corporation Commission

shall have authority to render judgment against such public service

corporation, person, or firm, for the amount of such overcharge that

may have been collected from the public in violation of any legal

rate, or order of the Dommission, if necessary to insure the prompt

payment of the same to the Commission. Such judgment shall be a

lien upon the property of the public service corporation, person, or

firm, and shall be collected in the same manner that fines and

penalties imposed by the Corporation Commission are now authorized

to be collected by law, and, when collected, shall be paid

immediately by the Commission to the parties to whom it is due.
