Okla. Stat. tit. 21, § 21-554: Attorneys - Buying demands for suit - Misleading inferior

courts.

Every attorney who either directly or indirectly buys or is

interested in buying any evidence of debt or thing in action with

intent to bring suit thereon is guilty of a misdemeanor. Any

attorney who in any proceeding before any court of a justice of the

peace or police judge or other inferior court in which he appears as

attorney, willfully misstates any proposition or seeks to mislead

the court in any matter of law is guilty of a misdemeanor and on any

trial therefor the state shall only be held to prove to the court

that the cause was pending, that the defendant appeared as an

attorney in the action, and showing what the legal statement was,

wherein it is not the law. If the defense be that the act was not

willful the burden shall be on the defendant to prove that he did

not know that there was error in his statement of the law.
