43 C.F.R. § 4.125 – Hearing postponements.

(a) Good cause required. Postponement of a scheduled hearing generally will not be approved, except upon a showing of good cause and reasonable diligence in preparing for the hearing.
(b) Timing of motion. A party must file a request for a postponement at least 21 days prior to the date of the hearing absent compelling circumstances. The ALJ will not grant a request for postponement made less than 10 days in advance of the hearing unless all parties agree to the postponement or the party requesting a postponement demonstrates that an emergency occurred which could not have been anticipated and which justifies the granting of a postponement.
(c) Form and content of motion. The motion for a postponement must state in detail the reasons why a postponement is necessary. The moving party must also make a reasonable effort to contact each party to determine whether an agreement can be reached regarding the requested postponement. In the motion, the moving party must state:
1. (1) Whether any other party agrees to the postponement;
2. (2) Whether any other party objects to the postponement; and
3. (3) Any steps taken to contact a party it was unable to reach.
(d) Limitation on postponements. A party generally will not be granted more than one hearing postponement, unless that party can show compelling circumstances that are beyond the party's control. In determining whether to grant more than one postponement to a party, the ALJ may consider the interests of justice and the relative prejudice to the parties.
