A more thorough explanation: A legislative rule is a regulation or rule created by an administrative agency that has the force and effect of law. It is issued by an agency in accordance with the authority granted to it by the legislature, and it carries the same weight as a law passed by the legislature. Legislative rules are binding on the agency itself and on the public, and they must be followed as if they were laws.
Example: The legislative rule requires all businesses to obtain a permit before operating in the city.
