Upon motion of any party or upon the order of the administrative law judge the hearing may be reopened for good cause at any time before the proposal for decision is issued. After issuance of a proposal for decision, the executive director (for decisions pending before the executive director) or board may order the hearing reopened for good cause at any time before a decision is made. If the hearing is ordered to be reopened, the executive director or the board, as applicable, shall remand the matter to SOAH or an administrative law judge for additional hearing and recommendation.
