Okla. Stat. tit. 12, § 12-412: Procedure

In the case of proceedings before a committee that two-thirds

(2/3) of the members of the full committee shall by affirmative vote

have authorized such witness, to be granted immunity under this act

with respect to the transactions, matters or things concerning which

he is compelled, after having claimed his privilege against self-

incrimination, to testify or produce evidence by direction of the

presiding officer and that an order of the district or superior

court for the county wherein the inquiry is being carried on has

been entered into the record requiring said person to testify or

produce evidence. Such an order may be issued by a district or

superior court judge upon application by a duly authorized

representative of the House of Representatives or Senate or of the

committee concerned. Neither house nor any committee thereof nor

any joint committee of the two houses of the Legislature shall grant

immunity to any witness without first having notified the Attorney

General of the State of Oklahoma of such action and thereafter

having secured the approval of the district or superior court for

the county wherein the inquiry is being held. The Attorney General

of the State of Oklahoma shall be notified of the time of each

proposed application to the district or superior court and shall be

given an opportunity to be heard with respect thereto prior to the

entrance into the record of the order of the district or superior

court. No witness shall be exempt from prosecution for perjury or

contempt committed while giving testimony or producing evidence

under compulsion as provided in this section.
