Okla. Stat. tit. 59, § 59-1470: Administrative hearing

When there is a cause to refuse an application or to suspend or

revoke the license of any polygraph examiner, the Council shall,

not less than thirty (30) days before refusal, suspension or

revocation action is taken, notify such person in writing, in person

or by certified mail at the last address supplied to the Council by

such person, of such impending refusal, suspension or revocation,

the reasons therefor and of his right to an administrative hearing

for the purpose of determining whether or not the evidence is

sufficient to warrant the refusal, suspension or revocation action

proposed to be taken by the Board. If, within twenty (20) days

after the personal service of such notice or such notice has been

deposited in the United States mail, such person has not made a

written request to the Board for this administrative hearing, the

Board is authorized to suspend or revoke the polygraph examiner's

license of such person without a hearing. Upon receipt by the

Council of such written request of such person within the twenty-day

period as set out above, an opportunity for an administrative

hearing shall be afforded as early as is practicable. In no case

shall the hearing be held less than ten (10) days after written

notification thereof, accompanied by a copy of the charges, shall

have been given the person by personal service or by certified mail

sent to the last address supplied to the Council by the applicant or

licensee. The administrative hearing in such cases shall be before

the Board.
