(b) Notice of hearing. When a hearing is scheduled, the appeals entity must send written notice to the appellant and the appellant's authorized representative, if any, of the date, time, and location or format of the hearing no later than 15 days prior to the hearing date unless—
(1) The appellant requests an earlier hearing date; or
(2) A hearing date sooner than 15 days is necessary to process an expedited appeal, as described in § 155.540(a), and the appeals entity has contacted the appellant to schedule a hearing on a mutually agreed upon date, time, and location or format.
(c) Conducting the hearing. All hearings under this subpart must be conducted—
(1) At a reasonable date, time, and location or format;
(2) After notice of the hearing, pursuant to paragraph (b) of this section;
(4) By one or more impartial officials who have not been directly involved in the eligibility determination or any prior Exchange appeal decisions in the same matter.
(1) Review his or her appeal record, including all documents and records to be used by the appeals entity at the hearing, at a reasonable time before the date of the hearing as well as during the hearing;
(2) Bring witnesses to testify;
(3) Establish all relevant facts and circumstances;
(4) Present an argument without undue interference; and
(5) Question or refute any testimony or evidence, including the opportunity to confront and cross-examine adverse witnesses.
(e) Information and evidence to be considered. The appeals entity must consider the information used to determine the appellant's eligibility as well as any additional relevant evidence presented during the course of the appeals process, including at the hearing.
(f) Standard of review. The appeals entity will review the appeal de novo and will consider all relevant facts and evidence adduced during the appeals process.
