(a) Requirement. A party who responded to an interrogatory, request for production, or request for admission with an answer or response that was complete when made must supplement or correct a prior response in a timely manner if the party learns that the answer or response is materially incomplete or incorrect and if the additional or corrective information has not been otherwise made known to the other parties during the discovery process or in writing.

(b) Order. At any time, an ALJ may issue an order directing the supplementation of an answer or response.
