In informal vs. formal rulemaking/adjudication, what triggers the formal requirements under A.P.A.?

Question

Quizplus · Accepted Answer

The A.P.A. requires formal rulemaking and adjudication when the authorizing statute requires the rule/decision to be made on the record after an agency hearing. This means that if the statute requiring the agency action explicitly states that there must be a hearing and that the decision must be made on the record, then the agency must go through the more formal process of rulemaking or adjudication.
