An attorney may withdraw an appearance before a hearing date has been set if:
If a hearing date has been set, or if the client's written consent is not obtained, or if the client is not represented by another attorney, an attorney must move to withdraw an appearance and receive permission from the presiding Administrative Law Judge to withdraw from the case. Unless the client is represented by another attorney or the motion is made orally in front of the client and the Administrative Law Judge, the attorney shall certify that:
Except when an Administrative Law Judge has granted an oral motion to withdraw in the presence of the client, the order granting permission for the attorney to withdraw shall be served on the client. If no new counsel has entered an appearance or the client has not notified the Administrative Law Judge of an intention to represent himself or herself, the order shall instruct the client to arrange promptly for new counsel or be prepared to represent himself or herself.
The presiding Administrative Law Judge may deny an attorney's motion to withdraw if the withdrawal would unduly delay the case, be unduly prejudicial to any party, or otherwise not be in the interests of justice.
