This updating supplement brings the Main Work The Rome II Regulation up to date and incorporates substantive developments since publication of the book in December 2008. In particular it draws attention to legislation implementing the Regulation in the United Kingdom, to recent ECJ cases concerning other EC private international law instruments, to new decisions of the English courts concerning the pre-Regulation rules of applicable law, and to recent books and journal articles providing further colour to the picture surrounding the Regulation since its adoption in January 2009. It is an essential purchase for all who already own the Main Work, and maintains its currency.
