Okla. Stat. tit. 19, § 19-901.30-2.1: Subpoena of witnesses and documents - Notice and

service - Rules - Hearings.

A. To accomplish the objectives and to perform the duties

prescribed by this act, the Public Employees Relations Board may

subpoena witnesses, issue subpoenas to require the production of

books, papers, records, and documents which may be needed as

evidence of any matter under inquiry, and administer oaths and

affirmations. In cases of neglect or refusal to obey a subpoena

issued to any person, the district court of the county in which the

investigations or the public hearings are taking place, upon

application by the Board, may issue an order requiring such person

to appear before the Board and produce evidence about the matter

under investigation. Failure to obey such order may be punished by

the court as contempt.

B. Any subpoena, notice of hearing, or other process or notice

of the Board issued under the provisions of this act may be served

personally, by registered mail, or by leaving a copy at the

principal office of the person required to be served. A return made

and verified by the individual making such service and setting forth

the manner of such service shall be proof of service, and a returned

post office receipt, when registered or certified mail is used,

shall be proof of service.

C. The Board shall adopt, promulgate, amend, or rescind such

rules as it deems necessary to carry out the provisions of this act.

Public hearings shall be held by the Board on any proposed rule of

general applicability designed to implement, interpret, or prescribe

policy, procedure or practice requirements under the provisions of

this act and on any proposed change to such existing rule.

Reasonable notice shall be given prior to such hearings, which shall

include the time, place, and nature of such hearing and the terms or

substance of the proposed rule or the changes to such rule.
