Hungary: Enforcing Arbitration Agreements by Applying Foreign Law
17 February 2022
Conflict of laws issues can have a pivotal effect on the effectiveness of arbitration when state courts are asked to enforce arbitration agreements. Has the approach of Hungarian courts crystalized in the last years in this respect? Can the contemporary Hungarian judicial practice and the new domestic legislation be characterized as arbitration friendly? This post provides the answers to these questions.
1. The Importance of Law Governing the Arbitration Agreement
The law applicable to the arbitration agreement is an evergreen topic of international arbitration: the governing law has decisive effect on the effectiveness of the arbitration agreement. It impacts not only the gateway to arbitration, but its existence and validity also comes up in various phases of arbitral proceedings.
However the dual nature of arbitration agreements, namely their debated classification as substantive or procedural contracts, complicates the search for the proper law.
Since the issue of governing law emerges mostly in front of state courts, which decide on their own jurisdiction when enforcing arbitration agreements, the old principle of “forum regit processum” calls for the application of the lex fori to this issue.
At the same time, the classification of arbitration agreements as substantive contracts and the principle of separability supports the application of other law, as lex causae, to assess the existence and validity of arbitration clauses.
When it comes to legal sources, except for Article VI (2) of the European Arbitration Convention, the leading international legal instruments of contemporary arbitration (like the New York Convention or the UNCITRAL Model Law) remain silent on conflict of laws issues in relation to arbitration clauses. It is also relatively rare that national laws expressly regulate the law governing the arbitration agreement.
In Hungary, the issue of applicable law to arbitration agreements has not been regulated until recently. Although this situation has changed with the adoption of the new Private International Law Code (“PIL”), effective from 2018, there is no yet case law under the new regime.
For this reason, before summarizing the provisions of the new law, we examine the Hungarian case law. Specifically, we analyse two appellate court decisions and trace the evolution of the domestic approach in relation to the law governing the arbitration agreement in the pre-award phase.
2. Traditional Approach – Lex Fori
Since the law governing the arbitration agreement had not been regulated previously in Hungary, state courts traditionally applied the lex fori approach to arbitration agreements.
A good example of this approach is the judgment of the Appellate Court of Budapest from 2011, rendered in a dispute involving a share purchase contract in relation to the business shares of a Hungarian limited liability company (target company).
The contract had been entered into by a Cyprian company as seller and a Swiss company as a buyer in Budapest, and it contained an arbitration clause in favour of the Arbitration Court of the Russian Chamber of Commerce and Industry.
The seller sued the buyer in front of the Hungarian courts, by challenging the existence of the share purchase contract and the arbitration clause by arguing that it was concluded on its behalf by a false representative, who acted based on a power of attorney, given by him in Cyprus 5 (five) years before the sales transaction.
The buyer disputed the jurisdiction of Hungarian courts based on the arbitration clause. However, in the opinion of the Hungarian courts, the power of attorney issued in Cyprus and the share purchase contract concluded 5 years later in Budapest had to be examined as one transaction. According to the courts, this transaction had the closest connection with Hungary, so they applied Hungarian law in the case.
Since the sale of the target company did not fall into the subject matter scope of the power of attorney, the Hungarian courts ruled that the false representative could not enter into a binding arbitration agreement on behalf of the seller.
The above decision can be criticized mainly for ignoring the principle of separability of the arbitration agreement, which prevented the court to examine the issue of representation, and the existence of the arbitration clause in the light of any other law than the lex fori.
3. A More Sophisticated View – Lex Causae
In a recent case from 2020, the Appellate Court of Győr has taken a more sophisticated approach. This case involved a legal dispute between an Austrian seller and a Hungarian buyer in relation to a supply contract for gas engines, and a subsequent service contract concluded between the same parties through representatives, to repair one of the engines, broken down in the post-warranty period.
The seller’s general terms and conditions (“GTC”) stipulated Austrian law as the governing law of the contract, and an ICC arbitration clause with a seat of arbitration in Innsbruck (Austria).
The buyer sued the seller for damage, arising out of the unsuccessful repair and subsequent forced sale of the engine, while the seller raised an exceptio arbitri, relying on the arbitration clause in the GTC.
While the GTC had been duly incorporated in the supply contract, the buyer argued that, despite the seller sending the GTC to him together with the service contract, he had not expressly accepted it. The buyer went on to argue that given the damage claim has arisen from the service contract, the Hungarian courts had jurisdiction.
The court of first instance, taking the traditional lex fori approach, applied Hungarian law to the arbitration agreement, according to which in the absence of express acceptance of a “surprise clause” in the GTC, like the arbitration agreement, the latter does not become part of the parties’ agreement. Consequently, the first instance court ruled that no valid arbitration agreement had been entered into by the parties.
However, the Appellate Court of Győr, acting as court of second instance, modified the first instance decision and applied Austrian law to the arbitration clause, according to which in case the parties do business in the same sector, or they have a continuous business relation, the provisions of the GTC become part of the contract if one of the parties intends to use it, and the other party is aware of this fact.
Based on the above, the second instance court ruled that the GTC and the arbitration clause had become part of the works contract, by tacit acceptance of the buyer, and therefore it terminated the litigation in that part that fell under the arbitration agreement.
4. Analysis and the New Hungarian PIL
The two above decisions showcase a paradigm shift in the approach of Hungarian courts in finding and applying the proper law of the arbitration agreement.
In the first case the courts took the traditional lex fori approach, and they applied domestic law to the contract and to the arbitration agreement, despite the apparent international dimensions of the case.
The second judgment indicates a departure from the strict lex fori approach towards the examination of the proper law of the arbitration agreement, which, as a so-called lex causae, can be distinct from the law of the state court, or from the law of the main contract, as well.
When it comes to the linking factor, the appellate court in the second case tacitly applied the lex loci arbitri principle, according to which, in the absence of choice of law by the parties, the arbitration agreement shall be governed by the law of the seat of the arbitration, reflecting the majority view of scholars. 
Even if the new Hungarian PIL was not yet applicable in the second case, because the facts arose before 2018, it seems that the second instance court was inspired by this new piece of domestic legislation.
This new law introduced arbitration-friendly provisions regarding the law applicable to the arbitration agreement with effect from 1st January 2018.
According to Section 52 of the Hungarian PIL, in the absence of law chosen by the parties, the substantive validity of the arbitration agreement shall be governed by the law governing the main contract, or by the law of the seat of arbitration, provided that the latter is in closer connection with the contract than the former.
When it comes to formal validity, the PIL sets forth a provision, based on which the arbitration agreement shall be valid, if it complies with any of the abovementioned laws or with the lex fori.
The above provisions clarify that instead of lex fori, the existence and substantive validity of an arbitration agreement can be evaluated based on separate law , as lex causae which reflects the principle of separability on the conflict of laws level.
In addition, the provisions in respect of formal validity can be interpreted as statutory expressions of the so-called validation principle.
Hopefully, when applying the provisions of the PIL in the future, Hungarian state courts will follow the pro-arbitration approach taken by the Appellate Court in the second case, and they will give effect to international arbitration agreements under the new arbitration friendly domestic conflict-of-law rules, too.

TIME IS MONEY! - PART IV – FLEXIBLE WORKING ARRANGEMENT AND FLEXITIME – DO WE HAVE TO PAY OVERTIME?
In the latest part of our series, we discussed the rules of irregular work scheduling, i.e. working time banking and payroll period in Hungary. In this article, we discuss the cases when employer transfers the right to schedule working time to the employee in whole or in part. In view of the COVID-19 pandemic situation and the widespread Home Office working arrangement, this type of working time schedule is becoming more and more popular, so we consider important to examine this institution.Read more »
HUNGARY: WHAT CLAIMS CAN THE ASSIGNEE LITIGATE AGAINST THE DEBTOR?
The assignment of claims is a common practice in business, yet under Hungarian law it has not been clear what rights are transferred to the new owner of the claim, and what claims can be litigated by the assignee. It has been also unclear whether the assignor and assignee can determine the extent of the rights transferred by assignment. Due to the recent decision of the Hungarian Supreme Court, that we analyse in this article, the picture has become clearer.Read more »
HOW TO SUE US RESIDENTS IN HUNGARIAN COURTS THROUGH ANCHOR-DEFENDANTS?
Based on the basic principle of international civil litigation, a person can usually be sued only in the courts of his or her own country. However, this makes it very difficult for a claimant who wants to enforce his rights against several defendants living in different countries. Can the jurisdiction of Hungarian courts existing in respect of a domestic defendant (the so-called anchor defendant) be extended to other, foreign defendants as well? In this article, we analyse the practical application of the new rules entered into force in 2018, based on a recent decision of the Hungarian Supreme Court.Read more »
