N.M. Code R. § 20.1.2.208
For a ULA hearing, discovery shall be governed by the provisions of the ULA. For other board adjudicatory proceedings, formal discovery is not a right, and therefore, formal discovery is discouraged and shall only be allowed by order of the hearing officer under the following procedures:
A. Grounds for discovery: Discovery shall only be permitted upon a determination by the hearing officer that:
(1) the type of discovery sought will not unreasonably delay the proceeding and is neither unreasonably burdensome nor unreasonably expensive; and
(2) the information to be obtained is relevant and is not otherwise reasonably obtainable, may be lost, or may become unavailable.
