Now in a fully updated seventh edition, this book remains an established treatise in the field of civil jurisdiction and judgments. It aims to make a full and complete statement of English law on civil jurisdiction and the effect of foreign judgments against the backdrop of significant uncertainty about the consequence of Brexit on the law of civil jurisdiction and judgments. The book looks in detail at: the law after the Brussels Regulation has ceased to operate as part of English law; the substance of the Lugano Convention, which the government hopes to join; the incorporation of the 2005 Hague Convention on Choice of Court Agreements into English law, and developments in the common law rules of jurisdiction, injunctions, and foreign judgments. This text aims to be an authoritative and comprehensive reference for all legal practitioners working in commercial law across jurisdictions as well as the judiciary.
