Volume one of this set of two texts presents a detailed exposition of the relevant EC rules in contract law that are applicable throughout the European Union, regardless of the national law of the contract. No commentary has been added to the text, which should be regarded as an account of the present state of the law. The use of EC regulations and directives in private law is a relatively novel concept. A growing body of EC legislation has been adopted with a view to determining various contractual obligations which must be complied with.
