Are certain formalities required for formal, hybrid, and informal rulemaking under the APA?

The correct understanding of the requirements for formal, hybrid, and informal rulemaking under the Administrative Procedure Act (APA) indicates that there are indeed no formalities required for informal rulemaking. Informal rulemaking typically follows a more flexible and less formal process compared to formal rulemaking. It generally involves a notice-and-comment procedure where agencies may publish proposed rules in the Federal Register and allow for public comments, but this doesn't require strict adherence to all of the procedural requirements associated with formal rulemaking, such as full hearings or the submission of official transcripts.

Formal rulemaking, on the other hand, is characterized by a requirement for a more structured process, including hearings that often involve the presentation of evidence and the opportunity for cross-examination, similar to court proceedings. Hybrid rulemaking may incorporate elements from both formal and informal processes depending on the nature of the rule being issued and the statutory requirements.

Since B states that there are never formalities required specifically for informal rulemaking, it captures the essence of the informal process as designed under the APA. Understanding this distinction helps clarify the nature of the different types of rulemaking and the varying procedural requirements that apply.
