How Does the CISG Interact with Common Law in International Sales Contracts?

Question from Tom, How Does the CISG Interact with Common Law in International Sales Contracts?

Answer from AI:

The United Nations Convention on Contracts for the International Sale of Goods (CISG) is a treaty that provides a uniform framework for international sales contracts. It is designed to facilitate international trade by providing a set of rules that are widely accepted and understood. However, its interaction with common law, particularly in the context of the United Kingdom, can be complex.

Interaction of CISG with Common Law

The CISG is designed to be a standalone legal framework, but it does not entirely replace national laws. Instead, it interacts with them in several ways:

• Gap-filling: The CISG does not cover all possible issues that might arise in a sales contract. When a matter is not expressly settled in the CISG, it is resolved in conformity with the general principles on which the CISG is based or, in the absence of such principles, in conformity with the law applicable by virtue of the rules of private international law.
• Interpretation: The CISG is to be interpreted autonomously, without reference to national laws. However, courts often look to their own legal traditions when interpreting the CISG, which can lead to different interpretations in different jurisdictions.
• Opt-out: Parties to a contract can choose to exclude the application of the CISG, in whole or in part. This allows parties to rely on national laws, such as the common law, if they prefer.

Challenges of CISG in the Common Law Context

While the CISG has been widely adopted, it has not been without criticism, particularly from common law jurisdictions like the UK. Some of the challenges include:

• Different legal traditions: The CISG is a compromise between different legal traditions, including civil law and common law. This can lead to difficulties in interpretation, as some concepts in the CISG are unfamiliar to common law practitioners.
• Lack of case law: Unlike common law, the CISG does not have a formal system of precedent. This can make it difficult to predict how a court will interpret the CISG.
• Uncertainty: The CISG leaves some issues unresolved, which can lead to uncertainty. For example, it does not clearly define when a breach of contract is “fundamental”, leaving it up to individual courts to decide.

Seeking Legal Advice

Given the complexities of the CISG and its interaction with common law, it is advisable to seek legal advice when drafting or interpreting an international sales contract. A legal professional can help you understand the implications of the CISG and how it interacts with the common law in your jurisdiction.
