Abstract: The subject of this research is the role of good faith in relational contracts and the key aspects of the theory of relation contracts adopted in common law countries. The research relies on the case law of England, United States, Canada, Australia and New Zealand. On the example of case law, the author attempts to elucidate the content of requirements of good faith in relational contracts, as well as bring forth a hypothesis of recognition of requirements of good faith conduct as an implied obligation for relational contracts. Moreover, this work demonstrates court rulings of English courts rejecting the connection with requirement of good faith in relational contracts and expresses the opinion that the process of search for place and role of requirements of good faith conduct in relational contracts is still ongoing. The main conclusion of the conducted research is the determination of the role and content of good faith in relational contracts, as well as description of the key concepts of the theory of relational contracts. The author presents demonstrative examples of court rulings of the common law countries, which establish a connection between good faith and relational contract, and set requirements for good faith conduct as an implied condition for long-term relational contracts.

Abstract: The subject of the research is the development and content of the concept of good faith in English law. The role of this legal principle has always been ambiguous and was largely determined by the content that English lawyers put into it at a certain stage in the development of the common law system. Formation of ideas about good faith included periods of its complete denial and periods of unconditional recognition at the level of doctrine and during law enforcement practice. Nowadays, the ideas of good faith in the law enforcement practice in England have become more widely applied in relational contracts and contracts that contain the obligation of contractors to adhere to this principle. The purpose of the article is to show the process of perception and development of the content of the idea of good faith in English law. The methodological basis of the research is the historical method and comparative law method, in particular, analysis of the relationship between theory and law-enforcement practice as well as features and stages of development of the object of study. The main conclusion of the study is that the doctrine of good faith has a long history in English law and its place and importance for the common law system have always been considered ambiguously. The author considers the main stages of the development of the concept of good faith from the period of its borrowing from the early canon law and Roman law up to the era of modernity. The differences in the content of good faith are indicated depending on the historical development of the law of England. The role of the idea of good faith for modern English law is highlighted and conceptual contradictions in the interpretation of the content of this principle in modern English law enforcement practice are revealed.
