N.M. Stat. § 59A-17-6.1
A competitive market is presumed to exist unless the superintendent, after notice and hearing, determines that a reasonable degree of competition does not exist within a market and issues a ruling to that effect. The ruling shall expire three years after issue unless rescinded earlier by the superintendent or unless the superintendent renews the ruling after a hearing and a finding as to the continued lack of a reasonable degree of competition. Any ruling that finds that competition does not exist shall identify the factors that cause the market not to be competitive and may also include a plan for enhancing competition. The superintendent shall monitor the degree and continued existence of competition in New Mexico on an ongoing basis. An interested party may petition the superintendent to initiate a hearing to examine whether a particular market is competitive or whether a particular market is no longer noncompetitive.
