HARMONIZATION AND UNIFICATION OF INTERNATIONAL COMMERCIAL LAW, PART 1

  1. Introduction

Considering the large amount of instruments created artificially or spontaneously aiming to harmonize and unify international commercial law, it is important to analyze which are the main problems arising from the present reality in order to deal with such issues and try to surpass their difficulties.

This paper highlights the main problems applicators in general (judges, arbitrators, etc), States, and International Organizations, including UNCITRAL, face when dealing with harmonization and unification of international commercial law. Consequently, the intention is that such problems are taken into account in order to improve the effectiveness of harmonizing/unifying instruments and mechanisms.[1]

Therefore, the subject issue of this paper concerns which problems emerge when harmonization and unification of international commercial law are sought; i.e. which difficulties should be considered when looking for efficient results on granting better-shaped-to-reality international commercial instruments,[2] since their creation until their application.

In this sense, problems can be divided into two categories: (i) one including problems accruing from the relationship between instruments and States; and (ii) other including problems accruing from the relation among instruments themselves. In the first category are included problems related to the drafting (and creation) of harmonizing/unifying instruments; their use (choice); their application by different applicators (judges, arbitrators); and situations that jeopardize their complete application, such as public policy issues and mandatory rules. In the second category are placed problems related to creation and drafting of instruments and their application.

However, before entering the subject itself, it is important to clarify some aspects concerning the terminology used, especially the terms unification and harmonization.[3] Unification takes place when (i) there is only one instrument to be applied; and (ii) the result of such application worldwide is similar enough that it leads to the avoidance of practical differences that may result in a specific choice of the applicator.[4][5]

Harmonization, in turn, has two meanings. The first one is used when an instrument works as model or source of inspiration to the creation or the application of another instrument in order to bring them closer and facilitate commercial relations. The second concerns harmonization seen as the harmonic coexistence of instruments.[6]

Therefore, any instrument can be used as a means of harmonization or unification, regardless the aim it was created for. Generally speaking, any source of international commercial law can be seen as a kind of harmonizing/unifying instrument. [7]

Considering the definition brought above, problems on harmonization/unification of international commercial law are any factors jeopardizing the fulfillment of at least one of the requirements of harmonization/unification as defined above.

Once unification requires (i) the existence of only one instrument (ii) applied similarly enough that the result of such application avoids practical differences, one may conclude that unification is not achieved if, regarding requirement (i), there is no harmonizing/unifying instrument to be applied or available instruments are not applied, or, regarding requirement (ii), the same instrument is applied differently, being this a reason for choosing one applicator or another.

Further, once harmonization requires the use of an instrument as model or source of inspiration in order to get them closer and facilitate commercial relations, problems arise when no instrument is used as model or source of inspiration or if such use does not result in the facilitation of commercial relations. The same is true when instruments do not coexist harmonically.

In the following topics, every problem mentioned above will be dealt with individually.[8] However, before moving on to such analysis, it is important to highlight that the existence of harmonizing/unifying instruments does not mean diversity itself is a problem. The existence of multiple instruments available means applicators can choose the one that best fits their relation. In addition, propagation of such multiplicity of instruments will, at last instance, show which are better suited for each relation and which should not be kept. In other words, practice will show which critics to which instruments are correct and which are not. The most important is that the content of one instrument does not harm the existence of a multiplicity of possibilities and their application. The application of each instrument must be made consistently worldwide no matter the applicator chosen.[9] Further, it is important to bear in mind that harmonization and unification should be sought as a means for a further objective.[10]

  1. Problems accruing from the relation between instruments and States
  2. Drafting, creation (regarding only the relation with States) and incorporation of instruments

The first problem has its origins in the existence of different juridical systems.[11] Such differences usually lead to long discussions during the drafting of harmonizing/unifying instruments. Therefore, the careful choice of their characteristics can help facilitating their drafting process and the fulfillment of goals.[12] During such process, every state-representative tend to defend their States’ own interests, which may result in incompatibilities. When it comes to the drafting of soft law instruments, conversely, text incompatibilities are not that relevant because their binding force is given by the parties or States that can adapt the content if they want. Another difference regards drafters, who usually are not state representatives, but experts on the subject matter.[13]

The second problem relates to the decision of a state to become bound by an instrument or not. When it comes to bringing international and transnational instruments to state legal order, it is the state itself the one to take decisions, such as: to become part to treaties, to use model law texts when drafting domestic legislation, to allow arbitration procedures, etc.[14] Such decisions take into account multiple aspects that may impair the effectiveness of harmonizing/unifying instruments.

Some of them are: the existence of other priorities;[15] the reduced number of State-parties;[16] the reduced personnel available to represent the country in conferences or meetings where the drafting is made[17]; apprehension on the results of the application of instruments;[18] avoidance of costs (which arise from the training to apply a new instrument);[19] lack of foreseeability regarding results of application;[20] preference for domestic law;[21] and incompatibilities with domestic law (mandatory rules and public policy issues).[22]

Reservations[23] and differences resulting from some states being bound to a treaty and others not also lead to discrepancies in their application as the content made bound on each state changes.[24] However, if reservations were not allowed, it is likely treaty acceptance would be reduced.

Also, the way each State faces international and transnational instruments can be considered a problem, especially regarding the hierarchical level international law instruments are placed in each legal order.[25] When domestic law prevails over international instruments, international commercial relations may be given a legal treatment that is not consistent with best practices.

In order to encourage states to become bound to a certain instrument, a provision containing an authorization to opt-out the entire text or to modulate its content may be considered a good idea. An example of such kind of provision is article 6 CISG.[26] The counterpart of such flexibility however is the existence of multiple possibilities of variation, harming the achievement of wider unification.[27]

Applicators may also avail themselves of provisions such as article 6 CISG when taking into account the limited scope of application of harmonizing/unifying instruments. In order to avoid depegage, national law may be preferred for it reaching a wider scope of application, so the same legal order is applied to all subjects dealt within the contract, which reduces the use of harmonizing/unifying

instruments. [28]

It leads to the conclusion that harmonizing/unifying instruments, although having a limited scope of application, should be harmonized with the content of other harmonizing/unifying instruments, in order to encourage their choice. In this sense, the wider the scope of application of harmonizing/unifying instruments, the more parties feel encouraged to allow their application to their commercial relations.

Further, when bringing harmonizing/unifying instruments to the domestic legal order, their translation is an issue to care. The use of different translation methods may lead to text distortions and, consequently, to misunderstandings on their application.[29] Even if drafting techniques are different, efforts should be applied by domestic law drafters so harmonization is kept. [30]

Another delicate issue regards changes made to the original text due to update reasons.[31] The consent of all States may be required once more and, usually, enormous difficulty is faced to reach consensus again. Therefore, problems arising from outdated provisions should be resolved through interpretation techniques, either considering the current practice of international commercial law, or making use of most recent instruments containing provisions on the specific subject. Provisions on filling gaps may be used for this purpose too.[32] In this sense, the more harmonizing/unifying instruments are known around the world, the easier it will be to find a solution to update their text without having to change the original text. Formulating agencies play a very important role in disseminating such knowledge.[33]

In addition, undue influence of domestic law on the application of international instruments must be avoided because such influence may harm the attainment of the aim pursued.[34]

  1. Application of harmonizing/unifying instruments

The application of harmonizing/unifying instruments is a fundamental step to reach harmonization and unification. Therefore, every aspect in their reaching will be analyzed separately.

As it was explained before, unification is reached when there is one instrument being applied and its application is similar enough that it avoids practical differences harming such application. Reaching harmonization, instead, means one instrument is used as a model or source of inspiration to others either through interpretation or drafting in order to facilitate commercial relations, or their harmonic coexistence.

Bearing these definitions in mind, one concludes it is the way the instrument is applied that determines whether it was used to harmonize or unify international commercial law.

Therefore, when analyzing the application of harmonizing/unifying instruments, the following aspects will be taken into consideration: (1) who is applying the instrument; (2) which instruments the parties are allowed to choose and which instruments the applicator is allowed to apply; (3) the relation of such instruments with others (especially the ones of domestic legal order, mandatory rules and public policy issues); (4) stricto sensu application of instruments.

As aspect (1) influences aspects (2), (3) and (4), our analysis will focus on aspects (2), (3) and (4), considering the applicator being a judge or an arbitrator when necessary.

Which instruments the parties are allowed to choose and which instruments the applicator is allowed to apply

Generally speaking, conflict of laws rules are strictly related to which instruments the parties are allowed to choose and to which instruments the applicator is allowed to apply.

In this sense, harmonizing/unifying instruments may be related to conflict of laws rules in three different forms: being the subject matter of such instruments, being the rule determining the application of harmonizing/unifying instruments on material rules, and filling gaps left by harmonizing/unifying instruments.[35]

As said above, some harmonizing/unifying instruments have as subject matter conflict of law rules. However, when it comes to international commercial law, material rules instruments are usually given preference, but it does not mean conflict of law instruments are not welcome.[36] In fact, the purpose conflict of law rules are built for has changed a little. [37]

Further, conflict of laws rules can be used to regulate the application of harmonizing/unifying instruments. Such rules can be seen from two different perspectives: (1) rules contained in the instrument that deals with its own application and (2) national conflict of law rules allowing or not the application of harmonizing/unifying instruments.

From the first perspective, conflict of law rules could fit for self-applicable instruments when states are bound to them,[38] but should not be used as the first option rule determining their own application because it could lead to distortions on the application of the instrument. Anyway, such instruments are ready to be applied and will be applied if application criteria are met.[39]

Instruments that are not self-applicable or although self-applicable are not being used as such (in case the state is not bound to them) depend on party autonomy to become applicable. Non-binding instruments, in turn, usually contain parameters that indicate situations to which they could apply, but still depend on party autonomy to be applied.

When it comes to the application of non-binding instruments, also said non-self-applicable, conflict of law rules play an important role[40] and dispute settlement provisions too. The large majority of states allow only the application of laws (and not rules of law) through conflict of law rules.[41] Therefore, the main problem impairing unification/harmonization concerns the recognition of legislative competence of other authorities by states.[42]

The dispute settlement method chosen plays also an important role. When parties choose arbitration, their scope of choice regarding the applicable law is wider. The application of soft law instruments can be authorized as it depends on party autonomy and, therefore, parties’ choices.[43] If the controversy is submitted to domestic courts instead, state rules will set forth what is allowed or not.[44] [45]46 In sum, the main concerns are (i) whether parties should be authorized to widely and freely choose (regardless the dispute settlement method chosen) and (ii) whether domestic judges should be authorized to widely and freely apply harmonizing/unifying instruments which the state is not bound to.

When it comes to filling gaps resulting from the incompleteness of harmonizing/unifying instruments, three perspectives are considered. One is wider and the other two are stricter. The wider regards the subject-matter of instruments. Differently from domestic law, harmonizing/unifying instruments concern a specific subject matter.[46] Therefore, commercial relations involving various subjects must be given coherent treatment considering every aspect concerned. Harmonizing/unifying instruments individually may not be considered sufficient. In this case, a possible solution is using multiple harmonizing/unifying instruments (when possible) or conflict of laws instruments.[47]

The two stricter perspectives are: (1) issues explicitly left out of the scope of the instrument and (2) issues in the scope of the instrument but not explicitly dealt within its text. Therefore, if some subjects cannot be dealt with within a unifying/harmonizing instrument, although related to it, they may be subject to rules that present at least some coherence to it. A text containing conflict of law rules that indicate the best solution is an option. Issues contained in the subject matter of the instrument, but not receiving specific treatment, should be subject to a provision on filling gaps regarding this kind of situation.

Therefore, the main problem concerning the filling of gaps is granting coherence to the treatment of all issues concerned. Harmonic solutions are the aim to be sought and can be reached if harmonizing/unifying instruments present coherent contents and their use is allowed by the state.

  • The relation of harmonizing/unifying instruments with mandatory rules and public policy issues

The relation between harmonizing/unifying instruments and mandatory rules and public policy issues is considered a problem because the last two limit party autonomy and act preventing the complete application of instruments in order to grant protection to national legal orders.[48]

Theoretically, when it comes to self-applicable instruments given binding force by the state, mandatory rules and public policy issues do not show if the instrument is applied for such a reason. This is so, because such issues should have been raised when the instrument was incorporated to the domestic legal order. Further, party autonomy is not used but to exclude their application. Therefore, conflicts with mandatory rules and public policy issues arise when a non-self-applicable instrument is applied.[49]

Thus, excluding cases related to the paragraph above, four issues concerning the conflict between mandatory rules and/or public policy issues and harmonizing/unifying instruments are the most relevant ones and will be considered here: (1) harmonizing/unifying instruments (soft law) applied as applicable law; (2) foreign law applied in a state whose national law is based on the same instrument as the foreign law; (3) provisions on mandatory rules and public policy issues contained in harmonizing/unifying instruments; and (4) public policy issues faced during proceedings for recognition and enforcement of sentences and awards.

  • In case of conflict between soft law instruments and national mandatory rules or public policy issues, the latter ones prevail.[50] If the dispute settlement mechanism is arbitration, as

arbitrators should deliver an enforceable award, mandatory rules and public policy issues are to be taken into account on a case by case basis in order to avoid problems of enforcement.[51]

  • In case of application of foreign law, conflicts with mandatory rules and public policy issues may occur.[52] Therefore, the more the domestic law and the foreign law are harmonized, the less mandatory rules and public policy issues will show up.
  • Provisions regarding mandatory rules and public policy issues and their conflict with applicable instruments are usually drafted to restrict the most the application of exceptions. As restrictive as their application may be, such kind of provision is always present, so exceptions are allowed and states feel encouraged to accept the application of harmonizing/unifying instruments.[53] In sum, states can avail themselves of an escape valve in order to protect their fundamental values and rules; but such protection should only be used in extreme cases.
  • Countries with different levels of development may have different levels of protection and, consequently, more or less tight enforcement standards.[54] Treaties on recognition and enforcement of judicial sentences are rare.[55] Conversely, when it comes to arbitration, the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitration Awards plays a very important role, facilitating the global circulation of awards. Although its success, public policy issues are still responsible for discrepancies on its application.[56] Further, the rising idea of transnational public policy is also relevant.[57] On the one hand, difficulties arise regarding the definition of its content and the possibility of its application before state courts (as the concept was created in relation to arbitration). On the other, transnational public policy allows applicants to take into consideration largely protected interests, fostering harmonization.[58] Regional public policy is also an issue to care, as organizations might prefer considering regional standards instead of national ones.[59]
  • Stricto sensu application of instruments

[1] The word Mechanism is used for the purpose of this paper as the way all available instruments can be used in order to harmonize or unify international commercial law.

[2] The word Instrument is used for the purpose of this paper as rules containing any kind of command or guideline that can be used in order to harmonize or unify international commercial law. It means that the instrument may be used for a purpose different to the one it was created for.

[3] It is possible to notice some terminological differences concerning texts written in different languages. Especially in French and in Portuguese three words are used: harmonizagao/harmonization, unificagao/unification and uniformizagao/uniformization. In English, the large majority of authors, including International Organizations, use two words: harmonization and unification. In this sense, unificagao/unification and uniformizagao/uniformization are treated as unification in this paper, as criteria used to treat them separately do not prevent their union. Also, such choice avoids misunderstandings regarding texts written in English.

Such instrument allows the parties to choose rules of law as long as they are “generally accepted” and are considered a “neutral and balanced set of the rules”. This is so to try to keep parties’ power balanced, otherwise one party could use its bargain power and impose its set of rules to the other.
