Staff of the Office of State Review may schedule and direct the attorneys for the parties, and any unrepresented party, to participate in a pre-review telephone conference with staff counsel. The purpose of the conference is to consider the possibilities of settlement, to simplify the issues, to resolve procedural problems, or to discuss any matters which may aid in the expeditious disposition of the appeal. In the absence of good cause, the failure of a petitioner's attorney, or of an unrepresented petitioner, to attend and participate in a scheduled pre-review conference shall result in dismissal of the request for review by the State Review Officer.
