Principles of International Commercial Contracts
# Principles of International Commercial Contracts

The Principles of International Commercial Contracts 2016 (most frequently referred to as UNIDROIT Principles and often also referred to as PICC) is a set of 211 rules for international contracts. They have been drawn up since 1984 by an international working group of the inter-governmental organization UNIDROIT, and they were ratified by its Council representing 64 governments of member states.

As soft law, these principles help harmonize international commercial contract law by providing rules supplementing international instruments like the CISG and even national laws. Most importantly in private practice, they offer a neutral contractual regime which the parties can choose, either by incorporation into their contracts (in whole or in parts), or by a straightforward choice of the UNIDROIT Principles (e.g. “This contract is governed by the UNIDROIT Principles of International Commercial Contracts 2016”; in practice such a clause is often combined with an arbitration clause).

The UNIDROIT Principles were first released in 1994, with enlarged editions published in 2004, 2010, and most recently in 2016 (including issues related to long-term contracts). Established with an international mind-set, they address many issues on which national legislators do not concentrate, such as foreign-currency set-off or hardship. Practitioners who use the principles describe them as a state-of-the art tool which is particularly useful when parties from different legal systems desire to agree on a neutral contractual regime. International law firm networks have an increasing number of committees concentrating on promoting the use of the UNIDROIT Principles in practice (e.g. the International Bar Association; Primerus Society of Law Firms).
