The financial crisis has brought about a revival of state protectionism across the globe. Most Western leaders have made a virtue of big government and state intervention; bail-outs and Sovereign Wealth Funds have been among the first responses to the economic contraction. Company law rules are one of the instruments frequently used to restrict or to discourage integration or to deter foreign investment. Examples for the new protectionism can be seen in a wide range of legislative and regulatory measures, for instance state measures preventing foreign takeovers, 'golden shares' or laws on foreign direct investment targeting Sovereign Wealth Funds, mainly from Asia.This book presents timely research by a number of company law and EU law experts into this field of law. The chapters cover a broad range of topics, spanning from takeovers/mergers over the one share-one vote debate through to the foreclosure of markets against Sovereign Wealth Funds.
