Sec. 821.9  Intervention and amicus appearance.

    (a) Intervention. Any person may move for leave to intervene in a 
proceeding, and may become a party thereto, if it is found that such 
person has a property, financial or other legitimate interest that will 
not be adequately represented by the existing parties, and that such 
intervention will not unduly broaden the issues or delay

the proceeding. Except for good cause shown, no motion for leave to 
intervene will be entertained if filed less than 15 days prior to the 
hearing. The extent to which an intervenor may participate in the 
proceeding is wholly within the law judge's discretion.
    (b) Amicus curiae briefs. A brief of amicus curiae in a matter on 
appeal from a law judge's initial decision or appealable order may be 
filed, if accompanied by written consent of all the parties, or by leave 
of the General Counsel if, in his or her opinion, the brief will not 
unduly broaden the matters at issue or prejudice any party to the 
proceeding. A brief may be conditionally filed with motion for leave. 
The motion for leave shall identify the interest of the movant and shall 
state the reasons why a brief of amicus curiae is desirable. Such brief 
and motion shall be filed within the briefing time allowed the party 
whose position the brief would support, unless good cause for late 
filing is shown, in which event the General Counsel may provide an 
opportunity for response in determining whether to accept the amicus 
brief.
