Adjudicative proceedings are those formal proceedings conducted under one or more of the statutes administered by the Commission which are required by statute to be determined on the record after opportunity for an agency hearing. The term includes hearings upon objections to orders relating to the promulgation, amendment, or repeal of rules under sections 4, 5 and 6 of the Fair Packaging and Labeling Act, but does not include rulemaking proceedings up to the time when the Commission determines under § 1.26(g) of this chapter that objections sufficient to warrant the holding of a public hearing have been filed. The term also includes proceedings for the assessment of civil penalties pursuant to § 1.94 of this chapter. The term does not include other proceedings such as negotiations for and Commission consideration of the entry of consent orders; investigational hearings as distinguished from proceedings after the issuance of a complaint; requests for extensions of time to comply with final orders or other proceedings involving compliance with final orders; proceedings for the promulgation of industry guides or trade regulation rules; or the promulgation of substantive rules and regulations.
