This book provides fair and acceptable solutions to hardship issues in long-term relational supply contracts. This book uses an approach to strike a balance between the traditional approach underlying classical contract law which emphasises the almost absolute prevalence of the principle of pacta sunt servanda and a flexible approach that is based on the principle of clausula rebus sic stantibus. This book argues for an emerging principle of pacta sunt servanda bona fide on the basis of the relational contract theory. Additionally, this book demonstrates how good faith can serve as a foundation for imposing a duty to renegotiate on the parties. The aim of this book is rather to propose how relational contract theory can be applied to the analysis of specific legal rules in general. Lastly, this boos highlights how the duty to renegotiate and the power to adapt a contract can be further developed upon the occurrence of hardship, based on good faith and the relational nature and characteristics of a long-term relational supply contract. This book explores and enriches the existing research on relational contract theory concentrates primarily on its application in domestic contract laws, particularly in the regulation of long-term contracts in American contract law. As an outcome this book provides a more feasible and satisfactory approach for courts or arbitral tribunals to undertake when facing hardship issues in international contract disputes. Overall, hardship themes, long-term relational supply contracts and good faith are examined extensively.

The unification of international commercial law has been a common course for every country of the world. The U.N. Convention on Contracts for International Sale of Goods (CISG) is a milestone in creating a uniform law in the field of the international sale of goods. The CISG coordinated divergent political, economic, and legal systems combined different contract laws and set up a comprehensive and independent legal framework for the international sale of goods. This book examines the basic requirements and criteria of the CISG’s interpretation and investigates how to achieve the uniform interpretation of the CISG based on interpretation rules in the CISG and through appropriate legal interpretation approaches. As a comprehensive and uniform legal framework for the international sale of goods, the CISG still has gaps to fill. Therefore, a uniform interpretation in gap-filling is equally important for the CISG. This book discusses gap-filling in the CISG, explains why and how to fill its gaps, clarifies gap-filling approaches, their order of application, and eventually concentrates on general principles and the uniform interpretation of the CISG. Another feature of the book is to discuss the supplementary materials that could be used to assist in the uniform interpretation of the CISG. PICC, foreign cases, UNCITRAL Digest, and the CISG Advisory Council opinions will be examined in detail to see whether and how they can fill the gaps in the CISG and promote its uniform interpretation. Only by clarifying the basic requirements and principles relating to the CISG’s uniform interpretation, can courts and arbitral tribunals correct their attitude toward and practices in the interpretation of the CISG. Only by following the autonomous interpretation approach, can the CISG achieve its goal to unify the sale of goods laws and promote the development of international commerce.

International commercial gas sale agreements are often characterised by a duration of twenty years or more. Consequently, when unforeseen events alter market conditions the contractual equilibrium originally found by the parties is disrupted, giving rise to the necessity to renegotiate and adapt the agreement. If negotiation fails, the parties in most cases submit the matter to arbitration. This comprehensive analysis of what can happen under such circumstances proceeds from an in-depth consideration of the power of arbitrators to intervene on the agreement in the light of arbitrability and procedural law. The author fully explains the complex special nature of gas pricing and contract clauses, and takes into account such features as the following, especially in the wake of the 2009 crisis as it affected the gas sector: - take or pay clauses; - mechanisms for gas price calculation; - price review and price re-opener clauses; - hardship provisions; - problems arising from the absence of a specific clause providing for adaptation/adjustment; - effect on contracts of the emergence and development of spot or traded gas markets; and - trend toward introducing spot-market elements into an oil-indexed price formula. The analysis draws on interviews with lawyers and arbitrators who have been involved in recent proceedings regarding gas sale contract adaptations, and also considers court decisions issued in setting aside or enforcing arbitration awards handed down in energy disputes. A central discussion throughout this book is the possible responses to the question of whether it is possible to determine a principle of law justifying the arbitrator’s power to intervene in contract adaptation. All professionals involved in the production, wholesaling, or distribution of gas will find this book indispensable. It will also be of special value to practitioners, policymakers, and regulators in the fields of energy law and environmental law.

Supply relations are often governed by so-called relational contracts. These are informal agreements sustained by the value of future cooperation. Although relational contracts persist in practice, research on these types of contract is only emerging in Operations and Supply Chain Management. This book studies a two-firm supply chain, where repeated transactions via well-established supply contracts and continued quality-improvement efforts are governed by a relational contract. We are able to characterize an optimal relational contract, i.e., to develop policies for supplier and buyer that structure investments in quality and flexibility in a way that no other self-enforcing contract generates higher expected joint surplus. A second goal is to compare the performance of different returns mechanisms in the context of relational contracting (quantity flexibility and buy-back contracts). Industry studies motivate the presented model.
