The Full Harmonisation of Standard Contract Terms – a Utopia? Die Vollharmonisierung des Rechts der Allgemeinen Geschäftsbedingungen – eine Utopie?

The article discusses the proposal for a consumer rights directive of October 2008, in which the European Commission suggests to move from minimum to full harmonisation of specific areas of consumer contract law. The article specifically examines whether full harmonisation of the law relating to the judicial control of unfair contract terms, even if politically desirable, will be feasible in the context of non-harmonised national contract law. Examples are presented for cases which were decided differently by national courts on the basis of divergent rules of general contract law. The article discusses whether the Draft Common Frame of Reference (DCFR) can be used by the European Court of Justice (ECJ) and the national courts as a common yardstick to measure the unfairness of a contractual term. Two problems present themselves: one is the question of legitimacy because, until now, the DCFR is no more than a scientific endeavour which in part rests on the autonomous decisions of its drafters and does not merely present a comparative restatement of Member States' laws; second, the DCFR makes excessive use of the term »reasonableness« so that, in many instances, its ability to give guidance in the assessment of the unfairness of a specific contract term is considerably reduced. The question of legitimacy could be solved by an optional instrument which could be chosen by the parties as the applicable law.
