After the completion of proceedings before the district director,
or as is otherwise indicated in this part, any party may in writing
request a hearing on any contested issue of fact or law (see
Sec. 725.419). A district director may on his or her own initiative
refer a case for hearing. If a hearing is requested, or if a district
director determines that a hearing is necessary to the resolution of
any issue, the claim shall be referred to the Chief Administrative Law
Judge for a hearing under Sec. 725.421.
