Interim rules are noncode rules that may add a temporary rule, supersede a rule, supplement a rule, or suspend a rule. A temporary rule will not have an IAC citation. Interim rules cannot repeal a rule but may suspend a rule. Under IC 4-22-2-37.2(b), every agency is granted authority to utilize the interim rulemaking process if (1) the agency has general rulemaking authority and (2) the Governor finds an interim rule is necessary.
