It was also mentioned that the European Commission maintained a central database of alternative dispute resolution bodies for consumer complaints , which were considered to be in conformity with the European Commission 's Recommendations on Dispute Resolution . According to a study prepared by the European Consumer Centres Network ( ECC-Net ) , published in December 2009 , approximately 12,000 cross-border complaints have been filed each year for the past three years within ECC-NET structure , out of which less than 500 resulted in alternative dispute settlement .
