The Companies Act 2014 makes the most far-reaching and fundamental changes to Irish company law in two generations, putting forward a radically different approach whereby the private company limited by shares will become the new model company. The structure of the fourth edition of this highly regarded title mirrors this new Act. The Act comprises over 1,448 Parts and represents the modern statement of the law applicable to the formation of companies, administration and management to their winding up and dissolution, incorporating the rights and duties of their officers, members and creditors. The Act commences on 1 June 2015 and introduces significant changes for companies operating in Ireland. This work has been expanded and revised to account for these legislative changes and important case law.
