After proper notice and an opportunity to be heard, an Administrative Law Judge may substitute a person or entity for a named party, or may add parties to a case.
Anyone who has an interest in the subject matter of a pending case and contends that the representation of his or her interest is inadequate may file a motion to intervene. After proper notice and an opportunity to be heard, an Administrative Law Judge may allow an interested person or entity to intervene.
If an Administrative Law Judge grants a motion for leave to intervene, the intervenor may participate to the extent allowed by the Administrative Law Judge.
No person or entity may intervene as a co-Petitioner with the Government in any enforcement action where the Government seeks a fine unless a statute allows it.
A person or entity to which the Government has properly delegated a governmental function may request to intervene, but may not be substituted for the Government.
