The Postal Service has filed an appeal with U.S. Court of Appeals, District of Columbia, challenging a ruling by the Postal Regulatory Commission concerning the USPS request for a rate increase under the price cap.  The PRC has already approved most aspects of the request, but it held that “certain mail preparation requirements [i.e., barcoding] were governed by restrictions on rate increases set forth in 39 USC 3622(d).”  The Postal Service argues that changes in its policy about barcode requirements are excluded from price cap consideration and that the PRC has thus exceeded its authority.  To read more, the relevant documents are PRC Order 1890, the Postal Service’s response, and the court filing.
