16. Rulemaking
basis and purpose statement
The federal APA and many state acts require that the promulgated rule be accompanied by a basis and purpose statement.  This statement can be analogized, to some extent, with the requirement of findings of fact and explanation that is required in adjudication.  In the federal system, the adequacy of the basis and purpose statement is frequently at the center in judicial review of the rule.  The basis and purpose statement may be required to demonstrate that the agency gave meaningful consideration to alternative formulations of the rule.  Where there are fact based elements in the rule, the supporting facts must be identified in the statement. 
follow own rules
A fundamental tenet of administrative law is that an agency must follow its own rules in order to make valid decisions.  One of the first things that the party does when a challenge to the agency is considered is to obtain copies of the agency rules and analyze whether what the agency did and the way that it did it was in compliance with the rules.
judicial review
Judicial review of informal legislative rules is less rigorous than judicial review of adjudication. The major issues in rulemaking will include the adequacy of the notice, whether the rule was within the statutory delegation of authority given to the agency, whether the basis and purpose statement is adequate, if one is required, and whether the minimal procedural steps were followed.
notice
Before an agency promulgates a legislative rule, notice and an informal hearing process may be required.  The notice can later be used to test whether the promulgated rule is within the terms identified in the notice.  If the notice and the final rule diverge too greatly, the rule may be upset for failure to follow statutory procedures.  The requirement of a hearing is frequently interpreted to mean that the agency must disclose the basis of the proposed rule with sufficient detail so that participants in the hearing can address the real concerns of the agency.
petition for rulemaking
The APA might provide that persons can petition the agency for rulemaking.  This would be used where no rules exist or where an amendment to existing rules is sought.  The agency has the discretion not to grant the petition.
promulgation, nonpromulgation, and recision
Rulemaking activities come in at least three forms.  The most common is the promulgation of rules following the statutory requirements.  Related to this is the recision of rules which generally must follow the same procedures as the promulgation.  An agency may begin a rule making procedure and then decide not to finally promulgate a rule.  In this nonpromulgation situation, the agency is not required to follow any particular procedures.
regulatory analysis
Regulatory analysis is a general way of describing legislation that requires that various studies be run prior to the promulgation of a rule, particularly at the federal level.  The analysis may cover such matters as the impact of the rule on small business, the impact of the rule on record keeping requirements, and similar matters that seek to limit the bureaucratic superstructure that seems to result from many rules.  The statutes often require that elaborate studies be run and conclusions be reached, but they also usually provide that failures to fully meet the statutory requirement will not be subject to judicial review.  In Oregon, the notice requirements may have to contain much of this analysis information.
types of rules
Rules come in various types.  Under the federal APA, in rare instances, formal rulemaking may be required.  This requires about the same procedures as would be used in an adjudication. The more common rulemaking procedure is notice and comment rulemaking, also called informal rulemaking.  In this procedure, notice is followed by an opportunity to comment, which may or may not involve an oral hearing.  Where an oral hearing is held, there is no statutory requirement for a closed record or for cross examination.  Statutes may provide for many variations off the general theme of notice and comment rulemaking.  The variations may relate to proof of facts or to cross examination.  These variations are sometimes referred to as hybrid rulemaking.  While congress can provide for hybrid methods, the courts cannot alter the hearing requirements that are identified in the statute.  Interpretative rulemaking is the issuance of rules, often in the form of a handbook, that explain the agency working interpretation of the statute. Interpretative rules are not binding on courts.  The authority to issue interpretative rules is usually implied in the agency and is not the product of a delegation of authority to the agency. Usually there are no procedural requirements for the announcement of procedural rules.
