Book excerpt: This new book offers a substantial framework for examining the competence or powers of the EC in the field of company law, and the requirements for the lawful exercise of these powers (the principle of subsidiarity and the observance of Article 43 EC in particular). In order to provide a clear understanding of the practical relevance of this framework, the author tests the provisions of specific EC company law instruments for compatibility with the EC Treaty. Although the substantial body of EC company law that has been built up over the years is covered, the focus is on EC company law instruments which have been adopted in implementation of the 2003 Action Plan. The book includes a survey of the various company law instruments (both pre-and post-Action Plan) which together make up EC company law, and discusses the objectives of EC company law policy. --
