The case was begun in 2004. The USA complained that the EC system of customs administration failed to ensure uniform administration by the customs authorities of the 25 member States. The USA also claimed that the review of administrative decisions on customs matters by the courts of 25 member States failed to comply with the EC’s obligation of “prompt review and correction of administrative action”.
The WTO issued a first report on June 16th, 2006. That report rejected most of the complaintsbut found a violation of GATT rules in three instances of application of classification and valuation rules.
The USA then appealed that first report. Now the Appellate Body actually reverses two out of the three specific violation findings made by the panel but finds that the classification of LCD monitors was incompatible. It also confirms that the EC customs system generally complies with the WTO rules.
That's nice! Both sides claim victory.
