Since World War II, international trade has grown exponentially and with it the importance of international law.  With the increased business between companies in different nations, the need for increased harmonization of commercial laws has become apparent.  Knowledge of international commercial law has become important for the transactional lawyer, even those outside major metropolitan areas.  Several years ago, LexisNexis and the International Bar Association jointly sponsored a survey of attorneys in eight countries, including the United States. The results of the survey reveal that while the practice of law is still largely domestic, the convergence of laws in certain areas, particularly trade and investment, is occurring.  The vast majority of the attorneys surveyed then believed that the international standardization of trade and investment law would be beneficial.


This guide collects sources for these harmonized commercial laws and leads the legal researcher to Internet sources on this complicated area of international law.  The guide begins with a discussion of the intergovernmental organizations (in some cases supranational) whose purpose is to harmonize commercial laws.  The guide then identifies the important treaties that have harmonized commercial law, particularly the law of the sale of goods, and finally identifies research institutes that support the harmonization of commercial law.  I have purposefully excluded conventions dealing with the transport of goods, the taking of evidence, insolvency, arbitration and procedural matters from this article.  Documents of GATT and the World Trade Organization are also excluded.  An excellent guide to international trade sources -- International Trade Law Sources on the Internet -- is available here.



European Union

One of the overarching goals of the European Union is the harmonization of private law as part of the development of the internal market.  The acquis communautaire refers to the body of European Union (“EU”) law that must be adopted by each Member State upon joining the European Union.  A significant part of the acquis includes uniform commercial law, which is a tool in developing the internal market.  The harmonization of contract law among EU member states has occurred thus far by the passage of directives and regulations, two types of EU legislation. 


The EU has made strides in this area and the European Commission in 2003 set forth an action plan on the harmonization of contract law within the EU [A More Coherent European Contract Law: An Action Plan, COM (2003) 68 (12 February 2003), 2003 O.J. (C 63) (March 15, 2003)].  Updated COM (2005) 456 (Sept. 23, 2005).  The Action Plan is a joint effort of the Internal Market, Enterprise and Health Protection and Consumer Affairs Directorates General of the European Commission.  In 2010, the European Commission issued a green paper dealing with European Contract Law [Policy Options for Progress Towards a European Contract Law for Consumers and Businesses, COM (2010) 348 (1 July 2010)].


Further information on this action plan is available at the Commission’s Health Protection and Consumer Affairs web site.


Comments on the Action Plan, both negative and positive, are available at the web site of the Directorate General for Health Protection and Consumer Affairs.


In 1989, the European Parliament first proposed the adoption of a European Civil Code.  1989 O.J. (C 158); 1994 O.J. (C 205); 2000 O.J. (C 377).  The European Commission responded to the Parliament’s call in a Commission document, COM (2001) 398, 2001 O.J. (C255) (Sept. 9, 2001).  Annex I of this document summarizes the acquis communautaire that deals with private law, in particular, the law of contract.   Annex II summarizes relevant international treaties dealing with substantive contract law issues.  Annex III analyzes the structure of the then existing EU directives on contract law and relevant international treaties.  Documents published in the Official Journal of the European Union (or O.J.) after January 1, 1998, are available in full-text online.

Common Frame of Reference Network- CFR Net

The European Commission organized this network of experts who aid in the development of the “common frame of reference” called for in the Action Plan.  Members include attorneys and consumer groups among other stakeholders in the development of European contract law.


European Judicial Network in Civil and Commercial matters

Sponsored by the European Commission, this network aims to “outline various national systems of civil and commercial law.”  It does not intend to provide legal advice. The site includes a useful page on "applicable law" or choice of law, and a separate page on applicable law discussing the relationship between the 1980 Rome Convention on the Law Applicable to Contractual Obligations and the Brussels I Regulation discussed in the Treaties section below.


Project Group- Restatement of European Insurance Contract Law

Sponsored by the European Commission, this group of academics, based at the University of Innsbruck in Austria, is developing a restatement of insurance contract law in Europe with the goal of creating a model law to be adopted by national legislatures.  A draft Common Frame of Reference for Insurance Contract Law is available on their web site under “Draft CFR.”  The English version is the authorized version with private translations available in sixteen other European languages.


The EU has harmonized selected national laws of Member States in the process of creating a unified internal market.  A detailed discussion of European Union law, types of EU legislation, the legislative process and EU institutions is beyond the scope of this article.  However, several useful research guides on EU law are available including:


International Jurisdiction in European Union E-commerce Contracts


European Union Law: An Integrated Guide to Electronic and Print Research

Organization for the Harmonization of Business Law in Africa (OHADA)

This intergovernmental organization was created pursuant to the Treaty on the Harmonization of Business Law in Africa among Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Comoros, Congo, Cote d’Ivoire, Gabon, Equatorial Guinea, Mali, Niger, Senegal and Togo.  Oct. 17, 1993, 1997 Journal Officiel de l’OHADA, No. 4,   (Official Journal of the Organization for the Harmonization of Business Law in Africa (OHADA)), November 1, 1997, available online  .  The Treaty was revised Oct. 17, 2008.  Membership has now expanded to sixteen with the addition of Guinea and Guinea-Bissau.


The treaty creates the institutions and structure for the harmonization of the law of contract, business organizations, securities, bankruptcy and arbitration in the member states, principally Francophone nations in Africa.  A Common Court of Justice and Arbitrage based in Abidjan, Cote d’Ivoire, is available to hear disputes.


OHADA has drafted and the member nations have adopted several uniform acts, including a uniform act relating to general commercial law adopted in 1997.  The texts of these acts are available online. Unidroit (described below) is assisting OHADA in drafting a Uniform Act on Contracts.


Union of South American Nations (UNASUR/UNASUL)

Originally created in 2001 as the South American Community of Nations (SACN).  UNASUR’s primary goal is to achieve economic integration in South America.  UNASUR’s 12 members include all members of the Andean Community of Nations and MERCOSUR, two regional trading blocs described below.  It should be noted that the UNASUR website is entirely in Spanish. 




Begun in 1991 as the Common Southern Market between Argentina and Brazil, MERCOSUR solidified that trade relationship while incorporating Paraguay and Uruguay.  Venezuela was just recently admitted as a full member to MERCOSUR. Venezuela’s admittance may be a serious blow to the legitimacy of the organization as Paraguay is protesting Venezuela’s admittance as violation of due process.  MERCOSUR’s goals include creating a common market for all member nations through harmonization of metrics, trade law, and economic policies.  MERCOSUR is dependent upon each country enacting domestic laws enforcing the decisions of the organization.  As a result, some policies are not enacted and others are not uniformly adopted.  It should be noted that the MERCOSUR website is entirely in Spanish and Portuguese.


Andean Community of Nations

Bolivia, Columbia, Chile, Ecuador, and Peru created the Andean Group in 1969 with the signing of the Cartagena Agreement. In 1996, the Andean Group became the Andean Community of Nations and Chile withdrew as a member.  The Andean Community of Nations has more effective supranational governance than MERCOSUR.  The Andean Community of Nations is using a variety of efforts, including harmonization of law, in an effort to create a common market.


African Economic Community (AEC)

Begun in 1994, the African Economic Community is intended to create a single African market with a common currency and central bank to help improve economic development in member nations.  With over 50 member nations, the AEC is organized through the seven regional economic communities known as the “seven pillars.”  The pillars include:


Community of Sahel-Saharan States (CEN-SAD)  –comprised of 18 member nations.


Common Market for Eastern and Southern Africa (COMESA)–comprised of 19 member nations.


East African Community (EAC) –comprised of 5 member nations.


Economic Community of Central African States (ECCAS/CEEAC) –comprised of 10 member states. 


Economic Community of West African States (ECOWAS) – comprised of 15 member states.


Intergovernmental Authority on Development (IGAD) – comprised of 6 member states.


Southern African Development Community (SADC)  – comprised of 14 member states.


Some nations are members of more than one pillar. 



The harmonization of commercial law has frequently been brought about by the adoption and ratification of treaties (primarily multilateral) that govern selected areas of commercial law.  This section describes the primary treaties dealing with commercial contracts.  A discussion of treaty research is beyond the scope of this article.  Useful guides on treaty research include: 


Researching Non-U.S. Treaties


Researching U.S. Treaties and Agreements


ASIL Guide to Treaties


UN Convention on Contracts for the International Sale of Goods

UN Convention on Contracts for the International Sale of Goods, 1489 U.N.T.S. 3, 19 I.L.M. 671 (April 10, 1980) (UN Treaty Registration No. 25567).

Protocol Amending the Convention of the Limitation Period in the International Sale of Goods, 1511 U.N.T.S. 77, 19 I.L.M. 696 (1980).

Arguably, the most successful of the international contract treaties, over 75 nations have adopted the UN Convention, including the United States and most Western European nations.  Notable exceptions are the United Kingdom and India. This treaty is frequently referred to as CISG or UN CISG.

Because of the relatively wide acceptance of the UN CISG, several excellent web resources on the treaty and court decisions interpreting the treaty provisions are available.  Some of the better resources include:


Claire Germain, United Nations Convention on Contracts for the International Sale of Goods: Guide to Research and Literature

A digest of cases interpreting the UN Convention, organized by treaty article.  Provides links to PDF versions of the digest and includes the United Nations document number for each analysis.


In addition, to UNCITRAL, there are a number of other UN committees that deal with the development of many aspects of international law, both public and private, and not merely international commercial law.  A useful page listing the more important UN committees dealing with the codification and progressive development of international law is here.


International Institute for the Unification of Private Law (UNIDROIT)

This international organization began as part of the League of Nations and became an official international governmental organization in 1940.  Unidroit currently has 63 members and has produced ten formal conventions, most recently the UNIDROIT Convention on International Interests in Mobile Equipment discussed further below, and numerous drafts and studies on international private law.


Unilaw Database

This database, available in both English and French, provides access to the Unidroit conventions, cases interpreting each convention and secondary sources discussing the convention.  The database begins with the 1956 Convention on the Contract for International Carriage of Goods by Road, 399 U.N.T.S. 189.


Unidroit Conventions - Full text versions are available online.


UNIDROIT Convention on International Interests in Mobile Equipment (November 2001), also known as the Cape Town Convention, this treaty entered into force on April 1, 2004 and harmonizes the laws of secured transactions where the collateral consists of mobile equipment.  Twenty eight (28) nations signed the treaty, including the United States, France, Germany and the United Kingdom.

Lugano Convention (Oct. 24, 1998), 1998 O.J.  (L 319) 9, 28 I.L.M. 620 (1998).  This convention adopts the same principles as the 1968 Brussels Convention above but applies to the Member States of the EU and the European Free Trade Association (Iceland, Norway, and Switzerland).


Organization of American States (OAS)

Originally founded as the Pan-American Union, this international organization with headquarters in Washington, D.C., has worked in many fields dealing with the Americas, with varying degrees of success.  Beginning in 1975, the OAS has sponsored quadrennial conferences on private international law that have resulted in the drafting of several conventions.  More information on these conferences known as the Inter-American Specialized Conferences on Private International Law (CIDIP) is available on the OAS web site.


InterAmerican Convention on the General Rules of Private International Law, Montevideo 1979, OAS Treaty Series No. 54, 1457 U.N.T.S. 6, 18 I.L.M. 1236 (1979) (CIDIP II).  Also available at the OAS Treaties database.

Treaties adopted during earlier Inter-American Conferences are available on the OAS web site.  A more extensive collection of documents from the Sixth and Seventh Inter-American Conferences on Private International Law (CIDIP-VI and CIDIP-VII) is available on the OAS website.  Though there has been no CIDIP-VIII   yet, OAS has listed a selection of possible topics for an Eighth conference.


United Nations Commission on International Trade Law (UNCITRAL)

UNCITRAL consists of delegations from 60 nations appointed by the U.N. General Assembly on a rotating basis.  The Commission acts through expert working groups, and has drafted conventions dealing with commercial law and been markedly more productive since the end of the Cold War in the late 1980s.


Case Law on UNCITRAL Texts (CLOUT)

Database on court decisions and arbitral awards related to UNCITRAL texts, including both conventions and model laws.

African Commission on International Law (AUCIL)

The African Union has sponsored a commission on the study and harmonization of international law.  While there is a website, it has not been updated frequently and features a sparse collection of materials.



The previous section describes the more important treaties dealing with contract law and the intergovernmental organizations that either drafted or sponsored such treaties.  Other organizations have issued standards, principles or best practices related to commercial law.  While these types of documents do not rise to the level of an enforceable treaty, they have been influential in the practice of international commercial law and have been cited by courts and arbitrators as sources of authority.


Unidroit Principles on International Commercial Contracts

These principles, available currently in English and French, were originally developed in 1994 by an international working group of academic attorneys representing all major legal systems of the world.  In April 2004, the Unidroit Governing Council adopted this revised version of the Principles.  Documents of the working groups that drafted the 2010 Principles are also available at the Unidroit web site.  The 2010 Principles are available in five official languages as well as three other foreign languages.

Study Group on European Civil Code (SGECC)

In 1989, SGECC was organized to study comparative law in Europe with a goal to create a model for a European Civil Code and a fully integrated common market.


SGECC has published the Principles of European Law (PEL), which provides common principles of international private law with regards to a functioning common market in Europe.  SGECC wants these common principles to be the framework for a European civil code.


The SGECC is comprised of nearly fifty law professors from across the EU who meet every other year to review developments made by the day-to-day working groups.  Each working group targets a particular area of international private law particularly uniform laws for contracts and moveable property.


Accademia dei Giusprivatisti Europei (The Academy of European Private Lawyers)

Formed in Pavia, Italy, in 1992, the Academy’s goal is to aid in the harmonization of European private law through scientific research.  The Academy publishes a European Contract Code, a model law for harmonization of contract law in civil law countries.


International Chamber of Commerce

This industry group based in Paris has been influential in harmonizing international contract terms as well as arbitration practices.



International Commercial Terms defines certain terms used in international trade that are frequently incorporated into international sales contracts.  The latest version of Incoterms was published in 2010 with the previous edition published in 2000.  The ICC began publishing these definitions in 1936 with subsequent revisions.  The preambles of the thirteen terms are available on the web site. 


The ICC has also published the definitions of terms and guidelines for their use in documentary credits frequently encountered in international trade -- Uniform Customs and Practice for Documentary Credits -- UCP 500 (Table of contents only; full-text is not available free online)

Meritas Law Firms Worldwide

Zimmerman’s Legal Research Guide

This guide has entries on nearly every international organization mentioned in this article.


American Journal of Comparative Law

This quarterly journal dealing with comparative law is published by The American Society of Comparative Law, Inc. (ASCL).  Founded in 1951, the journal publishes articles, essays, and book reviews dealing with comparative law and international private law.  Since 2009, every spring edition has included a “Private Law Bibliography” which includes recent important legal publications related to harmonizing international law.  The journal has also irregularly published a “Conflict of Law Bibliography.”


The International Lawyer

The Spring issue of this quarterly journal, an official publication of the Section of International Law of the ABA, is especially helpful, providing an extensive review of the international legal development of the previous year.  Quality varies from entry to entry, but overall it is well organized and thorough.  The spring issue is organized by area of law and by geographic region.  A review of sections on regional developments can identify harmonization of law efforts from the previous year.



Ius Commune Casebooks for the Common Law of Europe

This joint initiative of the University of Maastricht and the Catholic University of Leuven endeavors to develop casebooks on various aspects of European law.  The casebooks emphasize the effect of EU law and the law of the European Court of Human Rights on the harmonization of European law. 

A list of published casebooks  (including tables of contents, citations to book reviews, and order information) and a list of casebooks in progress with a provisional table of contents are both available online.

This guide focuses on free Internet sites that are sources of information on the harmonization of international commercial law, particularly contract law.  Due to its relatively short length, I necessarily limited my discussion to the more prominent treaties and international organizations.  The related topics of European Union law, treaty research, and international trade law are beyond the scope of this guide.  Detailed guides on these related topics (many of which were referred to above) are available on Globalex /, LLRX and other web sites.
