This chapter offers an introduction to Austrian arbitration law. It provides a chronological overview of the individual chapters of the Austrian Arbitration Act, with the most important provisions in each chapter being discussed in more detail. This chapter provides an overview of the most recent arbitration decisions of the Austrian Supreme Court as well as a short description of the legal framework regarding investments in Austria. It aims to familiarise the reader with the fundamental principles of Austrian arbitration law and emphasises the advantages of Austria as a neutral and arbitration-friendly seat for any kind of arbitral proceedings.

Austria has successfully defended its position as one of the leading hubs of international arbitration in Europe over the past few years. Its strong reputation is based on a reliable legal framework dating back to the codification of the Austrian Code of Civil Procedure (ACCP) in the late 19th century. To meet the requirements of modern arbitration and the needs and demands of legal practice as well as to stay one step ahead of its competitors, Austria has amended its arbitration law twice since 2006. Prior to these major reforms, only a few minor changes had been introduced since 1895. Together with its arbitration-friendly jurisprudence, this modern legal framework has contributed to the high popularity of Austria as a place of arbitration. The strength and steady growth of Austria’s reputation are supported by its leading arbitration practitioners, who enjoy an excellent reputation not only as party representatives and arbitrators, but also at the academic level. The legal education in the field of arbitration and the training of thousands of students having an interest in international arbitration becomes obvious every year when the Willem C Vis International Commercial Arbitration Moot takes place in Vienna. The University of Vienna in particular has gained recognition as a leading academic centre in the field of investment and commercial arbitration. Moreover, Danube University offers a certified programme on international dispute resolution, with a focus on international arbitration. These efforts at the academic level will help to foster the strength and expand the international recognition of Austrian arbitration practitioners.
Aside from the legal framework and its background, the prominence of Austria as an arbitral seat is founded on its geographical location and stable political conditions, and Vienna and the other major cities in particular are easily accessible and provide a perfect infrastructure for accommodating the needs of users of international arbitration. Vienna, as the home of various international organisations, has maintained a significant position as a top venue for international arbitration for decades, which is attributable to the Vienna International Arbitral Centre, one of the world-leading arbitral institutions fostering the use of arbitration. Therefore, Vienna is one of the preferred places for arbitration, particularly for parties from central, east and southeast Europe.
Austrian arbitration law
The first codification on arbitration law was enacted as part of the ACCP in the 19th century. At that time, the legal environment was already arbitration-friendly. The former arbitration law provided for arbitral awards having the effect of a final and binding court judgment. Furthermore, the Austrian Enforcement Act already provided (and still provides) for an avoidance of exequatur proceedings for domestic awards. The law proved to be a well-functioning framework, and – together with the neutral status of Austria – served to attract a large number of East–West disputes and to maintain Austria’s reputation as an arbitration-friendly jurisdiction long after the fall of the Iron Curtain.
In 2006, the 1985 version of the UNCITRAL Model Law (the Model Law) was largely incorporated into the Austrian Arbitration Amendment Act 2006 to meet the recognised international standards of arbitration. These provisions apply to arbitration agreements and arbitral proceedings concluded or initiated on or after 1 July 2006. Therefore, provisions of the old law that provide for formal requirements may still be applicable today. Yet, according to section 583(3) ACCP, formal defects of an arbitration agreement are cured if they are not invoked by a party before entering into an argument on the substance of the dispute.
On 1 January 2014, the Austrian Arbitration Act 2013 came into force, providing for new proceedings for the challenge of an arbitral award, claims regarding the declaration of the existence and non-existence of an arbitral award, and for proceedings concerning the constitution of an arbitral tribunal. Since this latest revision, the Austrian Supreme Court is the first and final instance in relation to these proceedings in most cases. Austria is therefore one of the few countries where arbitral awards are subject to only a single instance of set-aside proceedings.
The current arbitration law is embedded in Part 4 ACCP and closely follows the structure of the Model Law, with Chapters 1 to 10 including provisions on:
- the law’s scope of application;
- arbitration agreements;
- constitution of arbitral tribunals and the challenge of arbitrators;
- jurisdiction of arbitral tribunals (including jurisdiction for interim measures);
- conduct of arbitral proceedings;
- the making of awards (including the applicable law) and termination of the proceedings;
- proceedings on setting aside an award;
- recognition and declaration of enforceability of foreign awards;
- applicable procedural rules on state court proceedings relating to arbitration; and
- special provisions on consumer and labour law disputes.
Unlike the Model Law, the Austrian Arbitration Act does not distinguish between domestic and international arbitration and applies to all proceedings, irrespective of whether the dispute is of a commercial character. Pursuant to section 577(1) ACCP, the Austrian provisions on arbitration apply to all proceedings having their seat in Austria. Furthermore, according to section 577(2) ACCP, a number of provisions are applicable even if the place of arbitration is abroad or has not yet been determined. These provisions mainly govern topics concerning court assistance and court intervention in support of arbitration. According to section 577(3) ACCP, certain provisions also apply where the place of arbitration has not yet been agreed and at least one of the parties has its seat, domicile or ordinary residence in Austria. This set of provisions concerns court assistance on issues relating to the constitution of the arbitral tribunal (and challenges of arbitrators).
Austria is a party to the New York Convention on the Recognition and Enforcement of Arbitral Awards of 1958 (the New York Convention) and the European Convention on International Commercial Arbitration. It is a member state of the International Centre for Settlement of Investment Disputes (ICSID) Convention, which entered into force for Austria in 1971, and of the Energy Charter Treaty and its subsequent documents, namely the Trade Amendment and Protocol on Energy Efficiency and related Environmental Aspects. In 2015, Austria signed the International Energy Charter. So far, the country has signed more than 60 bilateral investment agreements, mostly with capital importing states. Typically, they provide for investor–state arbitration under the UNCITRAL Rules, the ICSID or the International Chamber of Commerce Rules. However, with the entry into force of the Lisbon Treaty, the competence to negotiate and conclude agreements on investment protection has been shifted to the European Union.
Austrian arbitration law provides for a very broad scope of the notion of arbitrability. According to section 582(1) ACCP, any claim involving an economic interest – and therefore all pecuniary claims – that falls within the jurisdiction of the courts of law is arbitrable. Claims that do not involve such economic interest can only be subject to arbitration as far as they may be subjected to a settlement agreement between the parties. According to section 582(2) ACCP, claims in family law matters, claims based on contracts subject to the Tenancy Act or the Non-Profit Housing Act, and all claims relating to condominium property are non-arbitrable. However, section 582(2) ACCP does not contain an exhaustive list, and other statutes provide for further cases of non-arbitrability. For example, disputes arising out of collective labour agreements and matters of social security law are non-arbitrable according to section 9(2) of the Labour and Social Courts Act.
Content and form requirements of the arbitration agreement
Section 581(1) ACCP defines the term ‘arbitration agreement’ as an agreement by the parties to submit to arbitration all or certain disputes that have arisen or may arise between them in respect of a defined legal relationship, whether contractual or not. The arbitration agreement may be concluded in the form of a separate agreement or a clause within a contract. In other words, section 581(1) ACCP refers to minimum content requirements of a valid arbitration agreement. According to these minimum requirements, the parties must be defined or at least definable in the context of the contractual relationship, the arbitration agreement must refer to a defined legal relationship and the parties’ will to have their dispute resolved by an arbitral tribunal must be expressed in the arbitration agreement.
Section 583 ACCP regulates the relevant form requirements and provides that an arbitration agreement must be contained either in a written document signed by the parties or in an exchange of letters, telefax letters, emails or other communication between the parties that provides proof of the existence of the agreement. In addition, when a contract that fulfils these form requirements refers to a document that contains an arbitration agreement, it shall also constitute an arbitration agreement, provided that the reference is such that it makes the arbitration agreement part of the contract (ie, the arbitration agreement referred to does not need to be attached to the signed document). Furthermore, a defect of form of the arbitration agreement is cured in the arbitration proceedings by entering into an argument on the merits of the dispute, unless an objection is raised no later than together with the first argument on the merits. Once the formal defect has been cured, the respective party is barred from relying on it in the course of the arbitral proceedings, as well as in pertaining proceedings before state courts.
Consumer and labour law disputes
Disputes where at least one party is a consumer are, in principle, arbitrable. However, Austrian arbitration law stipulates in section 617 ACCP numerous preconditions for the validity of respective arbitration agreements.
Such arbitration agreements have to be contained in a separate document, distinct from the main contract. This distinct document must be signed separately by the parties. Thus, incorporation by means of reference would not constitute a valid agreement (ie, in general terms and conditions, or conclusion by any other means of telecommunication, such as email). Furthermore, the arbitration agreement with a consumer is only valid if it is concluded after the dispute has already arisen, and the place of arbitration must be expressly stipulated. The arbitral tribunal may only meet for an oral hearing and the taking of evidence at another place if the consumer has consented thereto, or if significant difficulties hinder the taking of evidence at the place of arbitration. In addition, if the arbitration agreement is concluded between an entrepreneur and a consumer, the consumer must, prior to submitting to arbitration, be provided with a written legal advice notice regarding the differences between arbitration and court proceedings. Moreover, if the arbitration agreement was concluded between an entrepreneur and a consumer, and where, either at the time of concluding the arbitration agreement or at the time the arbitral proceedings are commenced, the consumer did not have his or her domicile, ordinary residence or place of work in the country where the arbitral tribunal has its place of arbitration, the arbitration agreement is only binding if the consumer invokes it. Section 617(6) and (7) ACCP provides for additional grounds for the setting aside of an award if one party to the arbitration was a consumer. As such, arbitration proceedings involving consumers rarely ever occur in Austria.
The same limitations apply to labour law disputes, with an exception for disputes involving the management board members of stock corporations and managing directors of limited liability companies.
The Austrian Supreme Court held that the notion of a consumer under section 617 ACCP corresponds with the definition under the Consumer Protection Act, and that section 617 ACCP applies to corporate transactions. Whether a party may be qualified as a consumer has to be determined from an economic point of view (degree of influence on the management of the corporation). Therefore, in the particular constellation where minority shareholders are involved and where Austrian law is applicable, corporate disputes may be considered consumer disputes and the arbitration clause may be invalid if it is incorporated in the articles of association.
Appointment of arbitrators
In a deviation from the Model Law, Austrian arbitration law requires an uneven number of arbitrators pursuant to section 586(1) ACCP. Where the parties agree on an even number of arbitrators, the arbitrators appointed have to appoint another arbitrator to serve as chairperson of the tribunal. In the event that the parties have not agreed on the number of arbitrators, Austrian law stipulates that the tribunal shall consist of three arbitrators.
In addition, Austrian law provides for a default appointment procedure in multiparty proceedings, which is not covered by the Model Law. When several parties on one side of the proceedings fail to jointly appoint an arbitrator within the period of four weeks, any party to the arbitral proceedings is allowed to request the state court to appoint an arbitrator for this group of parties (section 587(5) ACCP). However, this does not lead to the opposing party losing its right to appoint an arbitrator of its own choosing. This provision lacks an equivalent in the Model Law.
Mandatory provisions, party autonomy and the discretionary power of the tribunal
Arbitration proceedings under Austrian arbitration law are characterised by significant party autonomy and, in matters not governed by party agreement, broad discretionary power of the arbitral tribunal regarding the conduct of the proceedings. This party autonomy and the discretion of the arbitral tribunal are naturally limited by mandatory rules. Among such mandatory rules are the parties’ right to equal treatment, the right to be heard, objective arbitrability and the rules on challenging an arbitrator, applications for interim measures and setting aside an arbitral award. However, Austrian law does not contain an exhaustive list of mandatory provisions. Whether a provision is of mandatory nature or not has to be derived from its purpose.
In accordance with the Model Law, the Austrian Arbitration Act does not bar a party from applying for interim measures before a state court, even if the dispute is subject to an arbitration agreement. However, the competence to issue interim measures does not lie primarily with the state courts. The arbitral tribunal may render interim or protective measures in accordance with section 593 ACCP.
This said, ex parte interim measures can only be granted by Austrian state courts as section 593 ACCP provides that a tribunal may issue interim measures only after hearing the other party.
The arbitral tribunal has the authority to render such interim measures as it deems necessary and even if such measures are unknown to Austrian law. Interim measures issued by an arbitral tribunal are enforceable before Austrian state courts and only subject to scrutiny on grounds similar to the grounds for refusal of enforcement of an arbitral award. Furthermore, Austrian courts enforce interim measures issued by arbitral tribunals having their seat outside Austria or in the event the seat of arbitration has not yet been determined without separate exequatur proceedings. Where the interim measure is of a type unknown to Austrian law, the courts may – after hearing the opposing party – transform it to a type of interim measure known under Austrian law that most closely reflects the measure as issued by the tribunal.
Challenge of arbitral awards
Section 611 ACCP sets forth the grounds for the setting aside of an award as well as the applicable time limits. Accordingly, an award is to be set aside in the following circumstances:
- a valid arbitration agreement does not exist, or the arbitral tribunal has denied its jurisdiction despite the existence of a valid arbitration agreement, or a party was under an incapacity to conclude a valid arbitration agreement under the law governing its personal status;
- a party was not given proper notice of the appointment of an arbitrator or of the arbitral proceedings or was, for other reasons, unable to adequately present its case;
- the award deals with a dispute not covered by the arbitration agreement or contains decisions on matters beyond the scope of the arbitration agreement or the plea of the parties for legal protection – if the default concerns only a part of the award that can be separated, only that part of the award shall be set aside;
- the composition or constitution of the arbitral tribunal was not in accordance with a provision of this chapter (of the ACCP) or with an admissible agreement of the parties;
- the arbitral proceedings were conducted in a manner that conflicts with the fundamental values of the Austrian legal system (public policy) – this provision is much narrower than the parallel provision contained in the UNCITRAL Model Law and many other jurisdictions, as violations of the agreed procedure constitute grounds for the setting aside of an award only if such violation is severe enough to constitute a violation of procedural public policy;
- certain requirements according to which a court judgment can be appealed by an action for reopening of the proceedings (certain criminal actions);
- the subject matter of the dispute is not arbitrable under Austrian law; or
- the arbitral award conflicts with the fundamental values of the Austrian legal system (public policy).
The grounds for setting aside based on non-arbitrability of the matter in dispute, and relating to the award conflicting with the fundamental values of the Austrian legal system (public policy), have to be considered ex officio. In general, an action for setting aside an award has to be brought within three months after the award has been received by the claimant. Importantly, the setting aside of an arbitral award does not affect the validity of the underlying arbitration agreement.
The most important amendment of the Austrian Arbitration Act 2013, which came into force on 1 January 2014, mainly concerns challenge proceedings – for almost all claims for the setting aside of an arbitral award, the Austrian Supreme Court is now the first and final instance (and also for claims regarding the declaration on the existence or non-existence of an arbitral award and state court assistance concerning the constitution of the arbitral tribunal). Only in disputes involving consumers and in matters of labour law do the former procedural rules of the Austrian Arbitration Act remain in force. Therefore, in these two matters, three instances are available, in principle, for the proceedings seeking the setting aside of the award.
Recognition and enforcement
Awards rendered by an arbitral tribunal having its seat in Austria are executory titles eo ipso under the Austrian Enforcement Act and do not require a declaration of enforceability of a domestic court. It is sufficient to enclose with the application for enforcement a copy of the award containing a confirmation of its final and binding nature and enforceability issued by the chairperson or, if the chairperson is unable to do so, by another arbitrator. The recognition and enforcement of foreign arbitral awards is governed mainly by the New York Convention. Austrian courts widely recognise the necessity for an internationally uniform application of the New York Convention.
Notably, where an arbitral award covered by the European Convention on International Commercial Arbitration of 1961 has been successfully challenged in the country of origin due to a violation of public policy, this does not by itself constitute a ground for refusal of enforcement in Austria, provided that the award is not incompatible with the Austrian legal order.
Recent decisions and cases
Remote hearings and the right to a fair trial
In a recent and widely discussed decision, the Supreme Court had to decide whether the conduct of a hearing exclusively via videoconference, ordered by the arbitral tribunal in the absence of an agreement between the parties, constitutes a violation of the right to a fair trial or the right to be heard. While the holding of a hearing and the taking of evidence by way of a videoconference is considered permissible under Austrian law if the parties agree, there was little clarity on this issue in the case of absence of an agreement between the parties.
However, the Supreme Court’s decision has now confirmed that, even in the absence of an agreement between the parties, an arbitral tribunal may order the hearing to be held by way of a videoconference without thereby violating the right to a fair trial or a party’s right to be heard. According to the Supreme Court, it is precisely when the administration of justice is threatened with gridlock in times of a pandemic that videoconferencing technology is an appropriate way to reconcile the demands of effective law enforcement and the right to be heard, and therefore does not constitute a violation of due process. Likewise, the conduct of an arbitration hearing by way of videoconferencing did not constitute a ground for challenge of the arbitrators.
Reasoning of arbitral awards
Austrian arbitration law expressly provides that an arbitral award must state the reasons on which it is based. In 2016, the Austrian Supreme Court ruled that insufficient reasoning of an arbitral award can constitute a breach of procedural public policy and renders the award susceptible to challenge.
However, in 2018, the Court ruled that this does not apply if the reasoning relates to circumstances that the court must in any case examine in fact and law in set-aside proceedings, without being bound by the arbitral tribunal’s decision. As examples of such circumstances, the Court cited in particular the validity of the arbitration agreement and the composition of the arbitral tribunal.
In a decision issued in 2019, the Austrian Supreme Court confirmed that insufficient reasoning of an arbitral award could, in principle, constitute a violation of the Austrian procedural public policy, which leads to the setting aside of the award. The assertion of this ground for setting aside, however, is precluded, if a request for an interpretation of the award would be possible and the claimant has failed to submit such a request for interpretation. Accordingly, if a request for interpretation of the arbitral award would have been possible, insufficient reasoning can be successfully invoked only if the request was made without this leading to the elimination of the deficiency in the reasoning of the award.
In 2018, the Austrian Supreme Court addressed the question of whether the arbitral tribunal’s decision not to take certain evidence constitutes a breach of procedural public policy. The Court discussed that the failure to take certain evidence with respect to an issue that is also deemed relevant by the arbitral tribunal may constitute a violation of procedural public policy if this suggests that the arbitral tribunal acted arbitrarily.
However, it shall not constitute a violation of procedural public policy if the arbitral tribunal formally justifies the non-taking of evidence or the failure to make a determination on the basis of the legal irrelevance of the evidence concerned.
In a separate decision, the Austrian Supreme Court held that the failure to serve an interim arbitral award to a party was in casu not a violation of the Austrian procedural public policy since, due to the non-service, the interim award did not become final and binding and hence was of no relevance in the set-aside proceedings with respect to the final award.
Likewise, the court held that non-transmission of a hearing protocol does not, in principle, justify annulment of the award on public policy grounds. This would only be conceivable, if at all, if the plaintiff had not received the protocol, although service was requested, and therefore was prevented from contesting the arbitral award.
Decision on costs
In a decision on the award of costs, the Austrian Supreme Court considered, inter alia, whether the amount awarded in an arbitral tribunal’s cost decision constituted a breach of public policy.
The court found that an exorbitantly high amount of costs may indeed constitute a breach of public policy and thus, justify the setting aside of the award. However, it compared the amount granted by the tribunal with the costs the award debtor had indicated in its own cost submission and established that they were comparable.
Finally, the Austrian Supreme Court confirmed that there is no general principle under Austrian law prescribing that the costs of arbitral proceedings should not be higher than the costs of comparable state court proceedings.
Declaration that a document represents a non-award
Austrian arbitration law expressly provides that a party may request a declaration of the existence or non-existence of an arbitral award, provided it has a legal interest in doing so. In one of its decisions, the Supreme Court has stated in this regard that the very existence of a dispute on this issue is sufficient to establish such a legal interest. The court also stated that this applies regardless of whether the applicant may raise objections against the document as executory title in potential enforcement proceedings.
Procedure for setting aside arbitral awards
The ACCP provides that appeals against court decisions must be subjected to a preliminary examination in which the respective court of appeal examines whether the motion is based on any of the statutory grounds for appeal and whether it was filed within the applicable time limit. If the appeal does not meet these conditions, the court must reject it. In August 2018, the Austrian Supreme Court confirmed that this applies by analogy to applications for setting aside an arbitral award.
Conflict of interest
In a recent decision, the Supreme Court once again had to evaluate contacts between arbitrators as grounds for challenge. As in previous decisions, the Supreme Court did not consider the fact that the arbitrator had several professional links with lawyers acting as counsel in the proceedings to be grounds for annulment. The Supreme Court thus followed a widely discussed decision from 2019. In this decision, the Austrian Supreme Court discussed the significance of an arbitrator’s law firm’s relationship with one of the parties’ counsel. In particular, the Court had to decide whether the fact that both law firms serve as co-counsel in an unrelated arbitration represents a conflict of interest.
According to the Court, when examining the impartiality of an arbitrator, the grounds for disqualification of state judges must continue to be used as guidelines and a strict standard must be applied. Further, the Court confirmed that while the IBA Guidelines are not normatively binding, they can provide guidance in assessing the grounds for bias. On this basis, the court found that the simultaneous cooperation between an arbitrator and a representative of one of the parties as joint legal representatives constitutes a circumstance that raises legitimate doubts as to the impartiality and independence of an arbitrator within the meaning of point 3.3.9 of the IBA Guidelines and granted the challenge of the arbitrator.
Austria is a party to 60 bilateral investment treaties (BITs), five of which have been terminated. They will, however, continue to apply (until 2023, 2027, 2029 and 2034 respectively) to investments made prior to their termination.
The Lisbon Treaty transferred the competence to conclude investment treaties with third countries from the individual member states to the EU. With respect to ‘extra-EU BITs’ that were concluded before the Lisbon Treaty, EU Regulation No. 1219/2012 stipulates that they shall remain effective until they are replaced with new EU investment agreements.
With respect to intra-EU BITs, on 5 May 2020, the majority of EU member states signed an agreement to terminate all BITs concluded between EU member states. in which it declared the investor–state arbitration clause in a BIT between the Netherlands and Slovakia to be incompatible with EU law. Austria, however, has not signed the agreement; it is therefore not applicable to intra-EU BITs between Austria and other European member states. Whether or not these intra-EU BITs will remain in force in the long term is unclear.The agreement is a direct consequence of the Court of Justice of the European Union (CJEU) decision in Achmea,
Despite the large number of Austrian BITs, so far there has only been one investment treaty claim brought against the Republic of Austria.Austrian investors, however, have made more frequent use of Austria’s BITs with other countries. Currently, 12 investment arbitration proceedings involving Austrian investors are pending before investment tribunals. In addition, 13 proceedings initiated by Austrian investors have already been concluded.
Austria is a very arbitration-friendly jurisdiction with highly efficient law on civil procedure, modern arbitration provisions, sophisticated case law and an arbitration centre (the Vienna International Arbitral Centre) with an excellent reputation, which introduced the new Vienna Rules in 2021.
Austrian courts are generally reluctant to intervene in arbitral proceedings. Owing to the latest amendments of the Austrian Arbitration Act, which provide for the sole and direct competence of the Supreme Court, arbitral matters are almost exclusively in the hands of some of the best judges in the jurisdiction. The expertise and experience of Austrian arbitration practitioners range from commercial arbitration through investment protection to the particularities of dispute resolution in practically any specific economic sector. Certainly, not only the Austrian arbitration experts, but also Austria’s arbitration-friendly arbitration law together with the recently revised version of the Vienna Rules will continue to attract parties to choose Austria as their arbitral seat.

 One minor reform was that of 1983 updating the form requirements for arbitration agreements and incorporation of one provision concerning the challenge of an award on the grounds of the violation of public policy.
 Section 577(2) ACCP enumerates the following provisions: section 578 (court intervention only in matters governed by the chapter on arbitration); section 580 (receipt of written communication); section 583 (form of arbitration agreement); section 584 (arbitration agreement and action before court); section 585 (arbitration agreement and interim measure by court); section 593(3) to (6) (power of state courts to enforce interim or protective measures rendered by an arbitral tribunal); section 602 (judicial assistance in the taking of evidence); section 612 (declaration of existence or non-existence of an arbitral award); and section 614 (recognition and declaration of enforceability of foreign arbitral awards).

 However, the mere fact that a shareholder sits on the board of directors does not automatically mean that his or her influence is significant: see Austrian Supreme Court, 25 August 2014, 8 Ob 72/14t.
 Special time limits exist with regard to the grounds for the setting aside of an award based on criminal actions.
 Where an arbitral award on the same subject matter has been finally set aside twice and if a further arbitral award regarding that subject matter is to be set aside, the court shall, upon request of a party, concurrently declare the arbitration agreement to be invalid with respect to that subject matter.
