In this case the defendant, a kitchen manufacturer, was subject to the rules as set forth in a code of conduct, the so-called "CBW-code of conduct". As a result, the obligation was imposed upon the defendant to use towards its own customers the general terms and conditions as set forth in this code of conduct.
However, the defendant did not comply with its obligations under the code of conduct and the general terms this code sets forth. Accordingly, defendant demanded its customers to pay the full price before delivery of the kitchen although the general terms and conditions of the code of conduct state that a maximum advance of 15% of the full price applies.
