If the judge, or any other person charged under the provisions of Sections 13-1-301 through 13-1-315 with providing an interpreter, believes that a person claiming to be entitled to an interpreter may not actually be deaf or hearing impaired, unable to communicate verbally because of his hearing disability, or otherwise not entitled to such services, the judge may, on good cause shown, hold a hearing to determine the extent of the person's handicap or disability and the bona fide need for interpreting services. If it is determined that the person is not entitled to such services, an interpreter shall not be provided. Except in a preliminary hearing in a criminal case, every deaf person whose appearance before a proceeding entitles him to an interpreter shall notify the appointing authority of his disability not less than five (5) days prior to any appearance and shall request at such time the services of an interpreter. When a deaf person reasonably expects to need an interpreter for more than a single day, he shall so notify the appointing authority, and such notification shall be sufficient for the duration of his participation in the proceedings. When a deaf person receives notification of an appearance less than five (5) days before such appearance, he shall provide his notification and request for an interpreter as soon thereafter as practicable.
