The aim of this thesis is to identify some of the obstacles to trade, that occurs on the common market, and to analyse the errors that still occurs in the national authorities application of the principle of mutual recognition. Is the principle of mutual recognition sufficient for the creation of a common market, or is there a need for additional measures to cope with the obstacles to trade that still exists on the common market? The problems related to the incorrect procedures of the national authorities and the fact that undertakings prefer to bring their products in to line with the rules of every single member state must be solved, if the principle of mutual recognition is to become trustworthy. On some areas, harmonisation ought to be chosen above the principle of mutual recognition, but in other cases an increased administrative collaboration, mandatory training for the national authorities or information campaigns intended mainly for undertakings could be the answer. The possibility to help undertakings to sue member states for damages should also be investigated. If these problems are solved, the principle of mutual recognition, in addition to harmonisation, could become an excellent tool for the upholding of the free movement of goods in the common market.
