35 Miss. Code. R. 1-01-401
The Commissioner is authorized by statute to promulgate rules and regulations consistent with and complementary to the law to enforce the laws administered by the Department. A rule or regulation is a statement of general applicability that implements, interprets, or prescribes policy, or describes a procedure or practice of the Department and may include responsibilities that are not specifically required by statute or by an existing rule or regulation. Rules and regulations do not include those items excluded in Miss. Code Ann. Section 25-43-1.102(i) from the definition of a rule. The terms "rule" and "regulation" are synonymous with each other, and the Commissioner uses both terms in referring to the rules promulgated and adopted. The following discussion of the rule-making process applies not only to rules but also to regulations.
