Private international law (PIL) addresses overlaps and conflicts between legal systems by distributing cases between the authorities of such systems (jurisdiction) and establishing what rules these authorities have to apply to each case(choice of law). A modular argumentation tool, Arg-tuProlog, is here presented that enables reasoning with rules and interpretations of multiple legal systems.

This collection of essays is written in honour of Adrian Briggs, Professor of Private International Law at the University of Oxford. It recognises his outstanding contributions to the study and practice of the conflict of laws in England and internationally. The essays, written by experts from several legal systems, address topics ranging across the subject’s conventional lines of demarcation (jurisdiction, choice of law and the recognition and enforcement of judgments) and extending to its frontiers. Each of them engages with a particular aspect of the subject’s work. Separately, Professor Briggs’ close colleagues outline his many contributions to teaching and the wider academic community in Oxford and elsewhere.

This article examines the choice of law methods developed in four legal systems for problems relating to the substantial or essential validity of contracts. The complicated questions of formation and capacity have had to be left aside. The first two parts of this article discussed the choice of law methods used by courts in France, Germany, and the United States. This concluding part deals with the law in England and the common law jurisdictions in Canada, and also, by way of epilogue, with the recently completed European Communities Convention on the law applicable to contractual obligations. Finally, some general conclusions will be offered about the patterns of law that have emerged in the course of this survey.

AbstractThis article explores a solution to the choice-of-law issues concerning both voluntary and involuntary assignments arising in a domestic forum. The focus is on English private international law rules relating to cross-border assignments. A distinction is made between primary and extended parties as the foundation for choice-of-law analysis. Drawing on insights from the distinction of the use value and exchange value of debts found in economics, this article proposes a new analytical framework for choice-of-law based on a modified choice-of-law theory of interest-analysis.

This chapter examines the choice of law rules that determine the law applicable to international contracts in New Zealand, comparing them to the Hague Principles. Private international law in New Zealand is still largely a common law subject, and the choice of law rules on international commercial contracts are no exception. The general position, which has been inherited from English common law, is that parties may choose the law applicable to their contract, and that the law with the closest and most real connection applies in the absence of choice. There are currently no plans in New Zealand for legislative reform, so the task of interpreting and developing the choice of law rules continues to fall to the courts. When performing this task, New Zealand courts have traditionally turned to English case law for assistance. But they may be willing, in future, to widen their scope of inquiry, given that the English rules have long since been Europeanized. It is conceivable, in this context, that the Hague Principles may be treated as a source of persuasive authority, provided they are consistent with the general principles or policies underlying the New Zealand rules.

This chapter looks at Liechtenstein perspectives on the Hague Principles. Rules on choice of law, including international commercial contract law, have been codified by virtue of the Act on Private International Law 1996 (Liechtenstein PILA). The Liechtenstein PILA does not expressly state that conventions will take precedence over national laws. However, it has been held by the Liechtenstein Constitutional Court that international treaties are of at least equal status to regular national laws and that national law must be interpreted in line with public international law. Moreover, an international convention will often be considered to be a lex specialis and be given precedence over national rules on that ground. Liechtenstein courts will refer first of all to (old) Austrian case law and legal literature when dealing with matters pertaining to the parties’ choice of law. Whenever these sources leave ambiguity to a specific question, Liechtenstein courts may and most likely will consider other persuasive authorities. The Hague Principles may constitute such persuasive authority.

This chapter explores South Caucasian perspectives on the Hague Principles. The rules of private international law in all three South Caucasian countries—Armenia, Georgia, and Azerbaijan—are primarily contained in statutes: the Chapter of Private International Law in Armenia (1998) and separate statutes on Private International Law in Azerbaijan (2000) and Georgia (1998). Article 1253(1) of the Armenian Civil Code and Article 1(2) of the Azerbaijani Act provides that the courts may apply international customs in the area of private international law. In so far as the Hague Principles amount to or eventually crystallize into customary international law, the courts may give effect to the Hague Principles in that manner. Before that happens, there is nothing in the legal systems of either of the three jurisdictions preventing the courts from citing for explanatory and persuasive reasons soft law instruments, such as the Hague Principles. That said, stylistically the judgments of the South Caucasian jurisdictions are often drafted in a very concise and skeletal manner. Soft law instruments and commentary might influence the reasoning of the judges, but they would rarely refer to them in the text of the judgment.

This chapter reflects on Ethiopian perspectives on the Hague Principles. Ethiopia does not have a codified law regulating matters of private international law, nor is there detailed case law from which one could derive key principles of the subject. While the shortage of private international law in Ethiopia is evident, the problem is most severe in the area of applicable law. In relation to party autonomy in choice of law, the Federal Supreme Court’s Cassation Division has handed down some interesting decisions, and these indeed have the force of law in Ethiopia. Nevertheless, the approach of the Ethiopian courts in respect of party autonomy is not very developed and clear, including in the field of international commercial contracts. While it would be prudent for Ethiopian courts to refer to the Hague Principles as persuasive authority, this requires awareness of the existence of the Hague Principles. In the long term, the Hague Principles will surely find their way into Ethiopian law.
