(5)In the absence of uniform rules at Community level, obstacles to the free movement of services and goods across borders or the freedom of establishment could be justified in the light of the case-law of the Court of Justice of the European Communities as long as they seek to protect recognised public interest objectives and are proportionate to those objectives. In view of the Community's objectives, as set out in the provisions of the Treaty and in secondary Community law relating to freedom of movement, and in accordance with the Commission's policy on commercial communications as indicated in the Communication from the Commission entitled ‘The follow-up to the Green Paper on Commercial Communications in the Internal Market’, such obstacles should be eliminated. These obstacles can only be eliminated by establishing uniform rules at Community level which establish a high level of consumer protection and by clarifying certain legal concepts at Community level to the extent necessary for the proper functioning of the internal market and to meet the requirement of legal certainty.
