Okla. Stat. tit. 63, § 63-2412: Notice of necessity of interpreter - Proof of hearing

loss.

Every deaf or hard-of-hearing person whose appearance in any

proceeding entitles that person to a qualified legal interpreter

shall make a good faith effort to notify the appointing authority of

the desire of the person for an interpreter. An appointing

authority may require a person requesting the appointment of an

interpreter to furnish reasonable proof of hearing loss when the

appointing authority has reason to believe that the person does not

have a hearing loss.
