Career Milestones

Kozolchyk’s Early Career: The Contextual Comparison: Positive Law and Living Law, Business and Legal Cultures and Archetypes of Commercial and Legal Behavior

His book Commercial Letters of Credit in the Americas, published in 1966, prompted Henry Harfield (then United States’ leading letter of credit practitioner and author) to refer to it as the best book (on letters of credit) in or out of the Americas. As noted by Harfield, this book was the first to compare United States’ and other representative nations’ letter of credit laws as well as everyday banking practices.  With time, this comparison deepened and Kozolchyk’s analysis of the written or “positive” and living law of commercial contracts included dominant features of business and legal cultures as apparent in values and attitudes, especially with regard to commerce and the protection of the rights of third parties.   His understanding of the socio-economic forces that shape contemporary commercial and banking law enabled his drafting of harmonized commercial and banking laws in more than a dozen common and civil law countries. It also facilitated his ability to compile and select those commercial and financial practices worthy of international customary law enactments such as the Uniform Customs and Practices for Documentary Credits (UCP 500, 1993).

In some of his comparisons, Kozolchyk noticed how some outstanding jurists such as Rome’s Ulpian used archetypal or model contractual behavior when determining how a contracting party’s discretionary powers were properly exercised.  One of the Roman jurist’s favorite archetypes was the “respectable man of affairs” (Bonus Vir).  Many centuries later the German Commercial Code of 1897 relied on the “honest and proper merchant” (Ordentlicher Kauffman) to discern how discretionary as well as unspecified contractual duties should have been performed.  Unlike the archetypal behavior of the French Code Civil’s “Good Father of Family” (Bon Pere de Famille) which was applied to merchants and non-merchants alike, the German archetype was distinctly commercial.  Aware of the need for a realistic banking archetype in the determination of when letter of credit documents had complied with the terms and conditions of the letter of credit, Kozolchyk proposed in his 1990 article Strict Compliance and the Reasonable Document Checker that banks and courts alike rely on the archetypal behavior of a knowledgeable, honest, and respected banker, acting as the checker of documents and paymaster of the letter of credit, the Reasonable Document Checker. This was not an arbitrary standard because the practices could be discerned in the manuals for the checking of letter of credit documents prepared by the most respected letter of credit bankers around the world.

The pre-existing method of the examination of documents was supposed to be one of strict compliance of the documents tendered by the beneficiary of the letter of credit with the letter of credit specifications.  And often strict compliance was interpreted by courts as requiring a mirror image consistency between the presented documents and the specifications in the letter of credit. In practice, this method was unrealistic, impractical and led to a constantly growing number of disputes and lawsuits in important financial centers.  On the other hand, the realistic and objective nature of the standard archetypal practice was assured by their provenance (widely observed manuals of checking practices) and the future availability of periodic revisions of these practices by document checkers throughout the banking world.

Kozolchyk showed that the most influential archetypal views on what is the reasonably expected contractual behavior usually take into account (1) the expectations of regular participants in the same transaction especially when these participants act interchangeably with the other regular participants. This was the case with the banks that issue, confirm, negotiate or pay on letters of credit. For it is inherent in the international letter of credit business that it can best be conducted by correspondent banks. Thus, the same banks that at times act on behalf of applicants for the credit at other times act on behalf of beneficiaries or of intermediary banks.  This interchangeability requires that when checking letter of credit documents, an issuing bank instinctively places itself in the shoes of its confirming, negotiating or paying bank, for it was only too likely that their next transaction would be as a confirming, negotiating or paying bank.   In addition, archetypal views also take into account (2) the expectations of those participants who find it necessary to entrust their assets to others acting as their fiduciaries and who possess a superior knowledge of the transaction or a stronger bargaining power.  Finally (3), the archetypal view also takes into account the manner in which the business interests of parties who are not regular participants in the transaction are affected by the transaction in question and then it reasonably tries to minimize these adverse effects.    When the practices are those of scenario (1), the expected archetypal behavior is of equal treatment.  The expectation with respect to the practices of scenario (2) is of a “brotherly” treatment. The entrusted fiduciary is expected to behave like an older and caring brother to the entrusting and dependent party.  The good faith and reasonableness expected from such a party is Justice Benjamin N. Cardozo’s “punctilio the most honorable” and his good faith must be the highest known to commercial man (Uberrima Fides).  In this analysis, the best practice differs from the standard practice because  it takes into account not only the expectations of equally situated regular participants in the transaction, but also of those who entrust their assets to others and of third parties whose interests are affected unfairly by standard practices, such as for example, broadly gauged disclaimers of liability.

Although renamed as the “International Standard Banking Practice,” Kozolchyk’s Reasonable Document Checker standard was adopted by UCP 500 in 1993.  It was also adopted by the United Nations Convention on Independent Guarantees and Standby Letters of Credit (1995),[5] by Article 5 of the Uniform Commercial Code of the United States (1995), by UCP 600 (2007) and by numerous national laws, regulations and court decisions.   The ICC facilitated the uniform application of this standard by undertaking  successive revisions of what is now a worldwide international standard banking practice for commercial letters of credit  (ICC No. 645 of  2007 and 2013) and for standby credits  (ISP98 and ICC 590 of 1999).   The international observance of this standard has avoided much costly and unnecessary litigation throughout the financial and trading world.

Kozolchyk’s Role in the Promotion of Comparative Commercial and Banking Law as a Tool for Economic Development

After four years of teaching and directing the comparative law program at the Southern Methodist University School of Law, Kozolchyk joined the RAND Corporation in 1964 as a resident consultant and researcher.   RAND’s renowned interdisciplinary approach to socio-economic and political analysis afforded him a unique opportunity to explore the use of commercial law as a tool for economic development.  His RAND study Law and the Credit Structure of Latin America (1966) identified legal and cultural obstacles to the availability of commercial and consumer credit at reasonable rates of interest in selected Latin American countries. It suggested the need for reform of the positive law as well as the adoption of commercial and legal practices more conducive to the facilitation of this credit.

This study was read by the late Dean Carlos Jose Gutierrez of the University of Costa Rica Law School who was also an influential member of the Costa Rican congress and a believer in the need to use the law, positive and living, as an essential tool in Costa Rica’s economic development. He had a sympathetic interlocutor in William Skidmore, the lawyer for the United States Agency for International Development (USAID) in charge of Central America law and economic development projects. Jointly, the University of Costa Rica and USAID (ROCAP) offered Kozolchyk the directorship of the Law Reform Project for Costa Rica and Central America (Proyecto de Reforma Juridica 1967-69).

This project involved interdisciplinary law and economic development studies. It also involved the writing of a commercial law textbook with Costa Rica’s highly respected Professor Octavio Torrealba as well as recommendations for future statutory, administrative and judicial reforms. The Proyecto’s three inter-disciplinary studies were on (1) Costa Rica’s industrialization Law and its reliance on import- substitution policies; (2) law and private corporate capital formation; and (3) law and access to commercial credit at reasonable rates of interest. All these studies yielded important data that was subsequently used in legislative and judicial reforms.

Among the important information yielded by the credit study was why a totally coercive version of legal certainty by incarcerating defaulting debtors (under the guise of their disobedience of contempt of court citations) failed to provide legal certainty and accessibility to commercial and consumer credit.  In fact, very few debtors were incarcerated because as stated by one of their supposed jailers:  in this country, everybody is overdrawn in his credit obligations, from the president to the judges who issue the contempt of court citations. Another important datum was the inappropriateness of the collateral as a source of repayment.  Creditors looked exclusively to real property and to the debtors’ personal liability as their source of repayment. Thus asset based lending did not exist and neither was there a functional system of notice that commercial creditors and third parties could rely on.

By identifying the reasons for the failure of the Costa Rican legal system to help with the most basic chores of economic development, the Proyecto planted the seeds of future reforms for Costa Rica and other developing nations.  When Kozolchyk returned to Costa Rica forty-five years later to help Costa Rican jurists draft Costa Rica’s law of secured transactions, some of his former students and research assistants who had become justices of the Supreme Court, high government officials, legislators, distinguished legal practitioners and law professors.  Contemporary Costa Rican law students continued to study with the Kozolchyk and Torrealba textbook and thus were constantly reminded of the need to conform Costa Rica’s positive law to the best commercial and financial living law practices. As noted in the recent dedication of Professor Victor Perez Vargas is the Editor in Chief of Costa Rica’s Supreme Court Law Review. In Professor Vargas’ book Case Law for the Study of Private Law (Jurisprudencia Para el Estudio del Derecho Privado) she gave the following dedication: “to Professor Kozolchyk: this book exists because you taught us how to study the living law of the courts” (Para el maestro don Boris Kozolchyk.  Este libro existe gracias a Usted que nos enseño a estudiar el Derecho viviente de los Tribunales).

Making Laws and Selecting Best Practices for the Implementation of NAFTA

In 1969, Kozolchyk joined the James E. Rogers College of Law of the University of Arizona as a law professor. After teaching courses on commercial and comparative law and on jurisprudence for 22 years, he took a two year leave of absence in 1991 to represent the USCIB at the ICC as one of the draftsmen of UCP 500.  He was also appointed as a member of the United States Delegation to the United Nations Commission on International Trade Law (UNCITRAL) where he participated in the drafting of the United Nations Convention on Independent Bank Guarantees and Standby Letters of Credit.  Meanwhile, the North American Free Trade Agreement (NAFTA) among Canada, Mexico and the United States was about to be ratified by the member countries.

Anticipating the need for harmonization of commercial laws and practices in the NAFTA region, Kozolchyk proposed the creation of three national research and drafting centers (one for each of the NAFTA countries); they would be responsible for the uniformity or harmonization of commercial laws and practices in the NAFTA region. The centers so designated were: The Faculte de Droit at the University of Ottawa, the Instituto de Investigaciones Juridicas of Mexico’s National University (UNAM) and the Kozolchyk National Law Center (NatLaw).

As large streams of payments started to flow across NAFTA’s national borders, the need for uniform or harmonized practices on the deposit and collection of checks became quickly apparent.  Accordingly, NatLaw jointly with the Canadian, Mexican and United States banking associations drafted guidelines for the deposit, endorsement, clearing and return of checks (1993).  It also drafted or coordinated the drafting of, among others: The NAFTA Truck Standard Transportation Practices (NASTRAPS) (1992-2000); The Standards for the Qualification of Real Estate brokers in Arizona and Sonora 1992-1996); and A Manual of Labor Laws and Practices of the Mexican Maquila (transformation industries) (1997). Also as part of this NAFTA implementation phase, the NatLaw coordinated and participated in the drafting of the Organization of American States’ Inter American Convention on the Law Applicable to International Contracts (1993).

Secured Transactions Laws as Tools for the Economic Development of the Americas and Beyond

Kozolchyk’s work with NatLaw on the uniformity or harmonization of everyday commercial and financial practices in the NAFTA region soon was absorbed by the larger task of encouraging economic development by increasing the availability of commercial secured credit at reasonable rates of interest in Mexico and subsequently in Latin America and other development regions of the world.  While Canada and the United States had access to such a credit, Mexico did not.  In the absence of such a credit, critical sectors of Mexico’s economy, such as its transformation industry (maquilas) or its agricultural sectors, were prevented from competing with entities that had access to such a credit. On a temporary basis, and until Mexico could enact the necessary changes to its laws and regulations on secured transactions,  NatLaw encouraged banks situated in United States border states to lend to Mexican maquila industries and exporters of agricultural products by relying on collateral located in the United States and subject to Article 9 of the UCC.

The following are two illustrations of how that financing worked.  A Mexican owner and operator of warehouses (O) he leased to United States manufacturers (M) applied to Mexican banks for a construction loan that would enable him to build two more warehouses needed by M and it had agreed to occupy once built.  M’s written commitment to lease the future premises was for a number of years and for rental fees that were demonstrably quite profitable to O.  O tried to obtain loans from Mexican banks and the lowest interest rate they had offered him was 35% per annum.  These banks did not accept the present or future leases as collateral, neither did they accept O’s contract rights or rights in receivables owed by M.  They only accepted real property mortgages as collateral on the existing warehouses and O’s personal liability as a principal obligor on the loan.  Kozolchyk and NatLaw suggested to O that he considered assigning his present and future leases, contract rights and accounts receivable to a Tucson, Arizona based subsidiary (O.1) and use it as collateral with United States banks located in Tucson, Arizona. Contrary to the Mexican construction loan, United States banks were willing to accept the lease obligations, contract rights and accounts receivable located in Arizona as collateral for a line of credit secured by Article 9 of the UCC and at a 7% per annum rate of interest.  Not surprisingly, such a line of credit enabled him to build a number of additional warehouses. Within three years following the new construction, the number of O’s employees had doubled from 7,000 to 14,000.

NatLaw also assisted in making similar lines of credit available to Mexican exporters of agricultural products, big and small.  As with the maquila’s leases and accounts receivable, the lines of credit to the Mexican and Sinaloan growers were made possible by storing the exported products in bonded warehouses located in Nogales, Arizona.  The collateral for these lines of credit relied on by United States banks were the negotiable warehouse receipts issued by these warehouses, which were also subject to Article 9 of the UCC.  This method of financing provided credit not only to large and medium sized Mexican exporters but also to small ones who typically entered into agreements with the larger ones to sub-lease their reserved spaces in the United States warehouses.

These experiences helped NatLaw convince the then Mexican Ministry of Commerce and Industrial Development  (SECOFI) of Mexico’s need to enact an up-to-date  law of secured transactions accompanied by an equally modern registry of security interests in business assets.  Hence, from 1996 to 2000, a drafting team comprised of Lic. Francisco Ciscomany, an attorney for SECOFI, John Wilson Molina, Esq. (a former student of Kozolchyk’s and subsequently a NatLaw staff attorney) and Kozolchyk prepared a draft for the consideration of SECOFI and of other Mexican government agencies. After several revisions, this draft became Mexico’s and Latin America’s first asset based, secured transactions law.

Meanwhile, in 2002, Kozolchyk as part of the United States delegation to the OAS acted as the chief drafter of what became the OAS Model Inter- American Law on Secured Transactions. It was adopted unanimously by the OAS and shortly thereafter, member nations started enacting their versions of the model law.  Accordingly, Peru, Guatemala, Honduras, Mexico, Chile, Costa Rica, El Salvador and Colombia enacted versions that varied in their closeness to the model law. Eventually, some of the most deviant versions such as those from Mexico, Peru, Chile and El Salvador underwent or are undergoing revisions intended to bring them closer to the OAS Model Law.

The overall success of the Model Law and its progeny has become apparent.  In a very poor country such as Honduras prior to the enactment of the law the number of filed secured loans in the registry of Tegucigalpa was of a few dozen per month and their collateral was mostly automobiles and trucks. Since the enactment of the law, the average of monthly filings in that registry has been five hundred and they include business vehicles, office and professional equipment,  contract rights, accounts receivable, and, most importantly for agricultural loans,  growing crops. Prior to the law only the owners of the land could pledge their crops as collateral. Presently, any legitimate possessor of the land can.

Meanwhile, Colombia and Mexico have continued to see their annual monthly filings grow and at least one tenth of Colombia’s  growth in its 2014 GDP of 5.1% (the most impressive in the Americas) according to a World Bank economist attributable to the eased access to commercial and consumer credit. In a recent report from Colombia’s ministry of economy, since the introduction of the collateral registry, some 960,000 filings had been completed.  While approximately 50% of these filings were related to converted filings from the prior system, 50% are new filings.  Of these filings only 45% are related to collateral that is classified as vehicles and the others are related to new types of loans.

Additionally, for the last five years, Kozolchyk and NatLaw, as part of its membership in the International Financial Corporation’s Global Alliance, has made considerable progress in introducing secured lending laws and registry regulations in African and Asian nations. Under the direction of its world renowned expert Dr. Marek Dubovec (a former Kozolchyk student), Ghana adopted its Registry Regulations in 2012 to support the newly created Collateral Registry – a first of its kind in Africa. In June 2014, Liberia launched its own Collateral Registry that is also supported by a set of regulations drafted with the assistance of Dr. Dubovec. NatLaw is currently working on a number of projects in Africa, including in Malawi, Nigeria, Sierra Leone, and Zambia that are making swift progress towards establishing their own registries.

Similarly, NatLaw has become a leader in the training of Latin American judges in “oral” or adversarial and fact oriented commercial and criminal trials which promise not only to improve the predictability of court decisions but also to make these trials transparent and thereby diminish the presence of corrupt practices. In Mexico alone, 3000 judges and clerks have been trained under the Oral Trial and Advocacy Skills Training Program of NatLaw.
