This second edition of Claeys & Casteels' annual guide to European Energy Legislation and Case Law may prove to be a handy information tool when you need to be aware of precisely how the law currently stands, and the reasons that led to that state of the law. The Handbook is not limited to nal acts of legislation, but includes where appropriate proposals, debates, and guidance from the legislature. The conclusions of the Council and of the European Council in particular are helpful for understanding and predicting legislation. The second half of the Handbook is devoted to case law, as legislation often requires interpretation by judgements and judgements themselves may call for some comment. Most of this Handbook's explanations take up the remarks that were published in the European Energy Journal during the course of 2014. They are not limited to energy law, but refer also to other elds of legislation whenever their application and interpretation may inuence and aect energy law.
