Okla. Stat. tit. 40, § 40-4-507: Self-incrimination

SELF-INCRIMINATION. No person shall be excused from attending

and testifying or from producing books, papers, correspondence,

memoranda, and other records before the Commission, the Board of

Review, the chairman of an appeal tribunal, or any duly authorized

representative of any of them, or in obedience to the subpoena of

any of them in any cause or proceeding before the Commission, the

Board of Review, or an appeal tribunal, on the ground that the

testimony or evidence, documentary or otherwise, required of him may

tend to incriminate him or subject him to a penalty or forfeiture;

but no individual shall be prosecuted or subjected to any penalty or

forfeiture for or on account of any transaction, matter, or thing

concerning which he is compelled, after having claimed his privilege

against self-incrimination, to testify or produce evidence,

documentary or otherwise, except that such individual so testifying

shall not be exempt from prosecution and punishment for perjury

committed in so testifying.
