3002.2—Statutory functions.
(a) Areas of jurisdiction.
The Commission has jurisdiction over changes in postal rates and fees under 39 U.S.C. 3622, and over mail classifications under 39 U.S.C. 3623. It issues recommended decisions to the Governors of the Postal Service on these matters. It also acts on postal patrons' appeals from Postal Service decisions to close or consolidate post offices under 39 U.S.C. 404(b). Further, the Commission investigates complaints of substantial national scope concerning postal rates, fees, mail classifications or services under 39 U.S.C. 3662. It also responds to requests of the Postal Service for advisory opinions on changes in the nature of postal services under 39 U.S.C. 3661. Because of the Commission's expertise, Congress occasionally asks it to undertake special studies on postal issues.
(b) Public participation.
Interested persons may elect to participate in Commission rate and mail classification proceedings as formal intervenors ( § 3001.20 ), limited participators ( § 3001.20a ), or commenters ( § 3001.20b ). Interested parties who believe the Postal Service is charging rates which do not conform with the policies of the Postal Reorganization Act, or who believe that they are not receiving postal service in accordance with the policies of title 39, may lodge a complaint with the Commission under section 3001.82. Persons served by post offices that the Postal Service decides to close or consolidate with other post offices may appeal such determinations under § 3001.111.
