As previously stated, the discussion of a European civil code has had a primary focus on the development of a unified European contract code. Proponents of a European code of contract law have largely been divided into two groups. One group favours the use of the acquis communautaire (the body of European Union law) as the basis of a unified European contract law. The other has preferred a foundation in the field of comparative law and analysis of the domestic contract law of member states of the EU. The latter view was the initially dominant opinion in the field, but more recently the Acquis position has come to the fore.
