Fieldfisher dispute resolution specialists Simon Sloane and Emily Wyse Jackson examine the issues of due process and procedural irregularities in the context of arbitration.
 
A version of this article was first published by Global Arbitration Review in its Guide to Challenging and Enforcing Arbitration Awards (Second Edition).

Introduction

The integrity of any dispute resolution mechanism depends on the observance of due process or procedural fairness.[1] Less obvious, particularly in the context of international arbitration, is what that concept entails and where its boundaries lie.

At what point does an unfavourable procedural decision become a violation of a party’s procedural rights?

The answer to this question is not just of theoretical interest. Two key characteristics of international arbitration are the flexibility afforded to parties (marshalled by the tribunal) to tailor the procedure and the robust framework that exists for the enforcement of awards rendered.

The concept of due process affects both of them: a tribunal’s procedural discretion is largely unfettered save for the requirement to observe due process, and a failure to do so is one of only a few widely recognised grounds for setting aside an award or refusing to enforce it.

Legal basis for due process

There is no single definition of ‘due process’ in international arbitration and the term itself is not used in the leading arbitral instruments. Rather, ‘due process’ encapsulates a number of key principles of procedural fairness recognised both in international rules and conventions and in the domestic law of developed legal systems.

A good starting point is the UNCITRAL Model Law[2] (the Model Law), which provides (at Article 18) that ‘the parties shall be treated with equality and each party shall be given a full opportunity of presenting its case’.

The Model Law forms the basis of the domestic arbitration law of more than 115 jurisdictions,[3] including Australia, Canada, the Dubai International Financial Centre and Singapore, and has been described as ‘representative of the mandatory requirements of procedural fairness which apply to international arbitrations in most jurisdictions’.[4]

Some Model Law jurisdictions, such as New Zealand, have also cited the rules of natural justice as providing a legal basis for due process.

For example, as was set out in the first edition of this chapter, the New Zealand High Court has affirmed that ‘[a]rbitrators must observe the requirements of natural justice’ and provided a comprehensive summary on what those rules require in the arbitration context.[5]

The various leading arbitration jurisdictions that have not based their domestic arbitration framework on the Model Law have adopted similar requirements.[6]

For example, the English Arbitration Act 1996 (AA) mandates that a tribunal shall ‘act fairly and impartially as between the parties, giving each party a reasonable opportunity of putting his case and dealing with that of his opponent’ (Section 33); while the French Code of Civil Procedure states that ‘[i]rrespective of the procedure adopted, the arbitral tribunal shall ensure that the parties are treated equally and shall uphold the principle of due process’ (Article 1510).[7]

In addition, the duty for arbitrators to act fairly and even-handedly finds expression in most major institutional rules: see Article 22(4) of the 2021 ICC Rules;[8] Article 14.1 of the 2020 LCIA Rules[9] and Article 17.1 of the 2013 UNCITRAL Rules.[10]

Content and requirements of arbitral due process

Although the precise articulation of the requirement of due process varies in different institutional rules and domestic arbitration statutes, at its core is a party’s right to be treated fairly and to have a reasonable opportunity to present its case and to deal with that of its opponent.

What constitutes ‘fair’ and ‘equal’ treatment and a ‘reasonable opportunity’ to present one’s case will depend on the circumstances.[11] In particular, ‘equal treatment’ does not necessarily mean treating the parties identically.[12]

Without attempting an exhaustive exposition of the requirements of due process, we have identified below a few recurrent themes in due process-based challenges.

Right to a hearing

In Model Law jurisdictions, tribunals are required to conduct a hearing if requested by a party (Model Law, Article 24(1)). A refusal in such cases can deprive a party of its right to be heard.

However, the lack of an oral hearing will not always result in a due process breach. Even when the Model Law provisions apply, a tribunal is not necessarily required to conduct an oral hearing if neither party has requested one.[13]

Section 34(2)(h) of the English AA grants discretion to a tribunal to determine ‘whether and to what extent there should be oral or written evidence or submissions’.

A topical issue in the light of the Covid-19 pandemic is whether due process is breached by a tribunal’s order, against the wishes of a party, that a hearing take place remotely rather than in person.

In most circumstances, a remote hearing will offer in all material respects, the same opportunity to be heard as a physical one.[14] Due process challenges on this basis have typically failed, therefore.

For example, in July 2020, the Austrian Supreme Court dismissed an annulment application based on a tribunal’s decision not to postpone a scheduled hearing in the light of the Covid-19 outbreak (as had been requested by the respondent) but to proceed remotely instead.[15]

The Court noted that videoconferencing technology, which is now widely endorsed by state courts, can ensure effective access to justice and enable the parties to exercise their right to be heard, whereas insisting on an in-person hearing during the pandemic would stall the proceedings.[16]

Similarly, in December 2020, the ICSID Administrative Council refused an application by Spain to disqualify a tribunal on the basis that its decision to hold a virtual hearing in the midst of the pandemic lacked impartiality and the ‘high moral character’ required under the ICSID Convention.

The Council observed that ‘[t]he Tribunal itself is best placed to assess and balance these risks and considerations [of ensuring due process and the expediency of the proceedings]’.[17]

Denial of opportunity to present argument or evidence

If a party is barred without good reason from putting forward evidence or making arguments on a relevant issue, this is likely to cause a due process violation.

However, examples of successful challenges based on evidentiary rulings are rare.[18] Issues such as extensions of time, the ability to introduce additional evidence and document disclosure ‘typically and almost inevitably are matters that fall within the discretion of the tribunal, which, after all, is primarily charged with deciding the matter fairly’.[19]

Tribunals have considerable discretion to determine whether evidence is necessary and admissible,[20] having regard to the relevant laws of the seat and rules of the institution, as applicable.

In China Machine v. Jaguar Energy, the Singapore Court of Appeal rejected an argument that the imposition of an ‘attorneys’ eyes only’ regime for document disclosure breached natural justice by limiting a party’s ability to inspect documents produced by the other side.[21]

The Court noted that the tribunal was ‘clearly conscious of the need to strike a balance between the competing interests of the parties’ and had deliberately built a safeguard into the process by allowing the affected party to apply to the tribunal for direct access to certain documents where necessary.[22]

By contrast, in its 2021 decision in CBS v. CBP, the same Court held that an arbitrator’s refusal to hear any witness evidence, despite one party contending that witness evidence was necessary in relation to a key issue in the case, breached the requirements of natural justice.

Significantly in that case, the applicable arbitration rules obliged a tribunal to hold a hearing for oral witness evidence at a party’s request (subject to certain limits).[23]

Due process does not entitle parties to unlimited rounds of submissions[24] or to ignore the timetable prescribed by the tribunal. As articulated by the Swiss Federal Tribunal, ‘[a]n entitlement to evidence exists only to the extent that the evidential submission took place timely and in compliance with formal requirements’.[25]

It may constitute a breach of due process if a tribunal ignores evidence or arguments that have been duly submitted, or makes its decision on arguments or evidence that have not been ventilated in the proceedings. In other words, a party’s right to be heard includes a right:

to have reasonable and fair notice: (A) from the opposing party of the case it must meet on each issue of fact or law [that forms] an essential link in the chain of reasoning leading to the relief it seeks . . .; and (B) from the tribunal of any other issue which the tribunal adopts as an essential link in the chain of reasoning leading to its decision on the matters before it

and

to have the tribunal make some attempt bona fide to understand, engage with and apply its mind to its case on [each of those issues].[26]

For example, in Fleetwood Wanderers Limited v. AFC Fylde Limited, the English High Court found that an arbitrator breached due process by failing to notify the parties of, or allow them to make submissions on, communications he had with a third party on a relevant issue.[27]

In Kazakhstan v. World Wide Minerals Ltd, a breach of due process was found where damages were awarded without either party having advanced submissions as to quantum on the basis (which ultimately transpired) that the claimant was only partially successful on liability.[28]

However, this type of argument will not succeed if the relevant argument or evidence was ‘in play’ but the party elected not to deal with it.[29]

Relatedly, the taking of witness evidence is not a uniform process across the international arbitration landscape, with different practices permitted in different jurisdictions.

The ICC Commission Report (published in November 2020) on the accuracy of fact witness memory in international arbitration[30] raises valid concerns regarding witness statement preparation and how this process should be considered by practitioners.

It rightly does not seek to prescribe how tribunals should deal with the matter. However, by proposing possible approaches tribunals might take, the ICC may have signposted another door into Alice’s Wonderland through which ‘due process’ challenges can be dragged by proverbial ‘white rabbits’.

Failure to act impartially

It has been said that, as well as the right to be heard, the right to ‘a disinterested and unbiased tribunal’ forms one of the ‘two pillars of natural justice’.[31]

It follows that an award may be challenged if an arbitrator fails to act fairly and impartially as between the parties.

However, the standard of proof for such an allegation is high and courts will be slow to conclude that an unfavourable procedural decision is indicative of bias against a party.[32]

For example, in BSG v. Vale, the applicant argued before the English High Court that an LCIA tribunal’s decision not to allow into evidence the 2,000-page transcript of parallel ICSID proceedings, three months after the hearing in the LCIA proceedings had closed, amounted to apparent bias.

This argument was given short shrift by the Court, which found that it was ‘plainly within the discretion of the Tribunal’ to decide whether to admit the evidence and that ‘new and dramatic evidence was needed to be put before the Arbitrators in order for them to be persuaded to take the exceptional step of admitting further evidence and opening up the arbitration’.

On the facts, the Court was ‘satisfied that there was no apparent bias, no procedural irregularity under s. 68 and, in any event, no substantial injustice’.[33]

Conclusion

As is apparent from the case law examples above, not every procedural decision made by a tribunal involves issues of due process and not every procedural irregularity by a tribunal will be a breach of due process; on the contrary, most will not.

The right to due process is a protection from egregious and injudicious conduct by an arbitral tribunal.
It is not intended to protect a party from its own failures and strategic choices,[34] nor to confer an entitlement to have every aspect of the procedure determined according to its preference.

Notably, some commentators have observed a move over time to narrow the language in which this right is expressed, with the intention not of diminishing parties’ rights but of minimising tactical abuse of more open language, as discussed above.

For example, although Article 15(1) of the 1976 UNCITRAL Rules stated that parties should be afforded ‘a full opportunity’ to present their case ‘at any stage of the proceedings’, Article 17(1) of the 2013 revision provides for ‘a reasonable opportunity’ to present one’s case at ‘an appropriate stage of the proceedings’.[35]

If due process has been breached, a party may (1) apply to the courts of the jurisdiction where the arbitration was seated to have the award set aside or annulled, or (2) challenge the award in the courts of a jurisdiction in which enforcement is sought.

However, as discussed in the following sections, the threshold for succeeding on such challenges is generally high and they should be treated with great caution.

Setting aside an award for breach of due process

Lack of due process is typically one of the limited grounds specified in domestic arbitration legislation as a basis for setting aside an award. However, as confirmed by a 2018 report on the practice of 13 major arbitration jurisdictions,[36] courts are largely supportive of arbitration and will be reluctant to set aside an award for purely procedural reasons.[37]

In England and Wales, for example, in the court years 2015–2017 and 2017 to March 2018, only one of 112 challenges on this basis was successful,[38] and in 2018–2019 again ‘very few’ such challenges succeeded.[39]

Interestingly, the number of these challenges brought in 2018–2019 in England and Wales dropped by nearly 75 per cent, causing one judge to express his ‘hope that parties were hearing the message that the hurdle for these applications is high’.[40]

In France, the proportion of successful challenges is higher than in England but still low: between 2016 and 2018, only one in four annulment claims succeeded.[41]

In Model Law jurisdictions, an award may be set aside if ‘the party making the application was not given proper notice of the appointment of an arbitrator or of the arbitral proceedings or was otherwise unable to present his case’.[42]

Some Model Law jurisdictions provide for additional due process-related grounds for setting aside an award.
For example, the Singapore International Arbitration Act also allows an award to be set aside when ‘a breach of the rules of natural justice occurred in connection with the making of the award by which the rights of any party have been prejudiced’.[43]

In England and Wales, Section 68 of the AA provides that an award may be set aside on the ground of ‘serious irregularity affecting the tribunal, the proceedings or the award’ that ‘has caused or will cause substantial injustice to the applicant’.

A 1996 report on the (then) Arbitration Bill explained that this provision was ‘designed as a long stop, only available in extreme cases where the tribunal has gone so wrong in its conduct of the arbitration that justice calls out for it to be corrected’.[44]

If this high threshold is met, the court may (1) remit the award back to the tribunal for reconsideration, (2) set aside the award or (3) declare the award ineffective in each case in whole or in part.

The primary remedy is remission, which must be ordered unless the court considers it would be inappropriate to do so (e.g., in cases of tribunal bias). An interesting issue in this regard is whether it is appropriate for the parties to incur further costs – and the tribunal to be further compensated – for time spent by the tribunal remedying its own breach.[45]

Section 68 of the AA sets out a ‘closed list’[46] of qualifying ‘irregularities’, including failure by the tribunal to comply with its duty under Section 33 to act fairly and impartially and to allow each party a reasonable opportunity to present its case, as well as failure by the tribunal to deal with all the issues that were put to it.

The term ‘substantial injustice’ is not defined in the AA but this element of the test was ‘designed to eliminate technical and unmeritorious challenges’.[47]

Although an applicant does not need to show that the outcome of the proceedings ‘would necessarily or even probably have been different’,[48] it must show that, had the breach not occurred, ‘the Tribunal might well have reached a different conclusion from that which it reached’.[49]

Other jurisdictions, such as Switzerland,[50] require an applicant to prove that the breach of process identified was outcome-determinative.

In Singapore, the test is whether the ‘rights of any party have been prejudiced’, which the courts have interpreted as requiring that the breach denied the applicant the benefit of arguments or evidence that had ‘a real as opposed to a fanciful chance of making a difference to [the arbitrator’s] deliberations’.[51]

An important requirement in many jurisdictions is that any breach of due process is raised promptly by the wronged party and, where possible, the tribunal is given the opportunity to cure the breach.

In England and Wales, this principle is reflected in Section 70 (which obliges a party first to exhaust any arbitral processes of review or appeal or any powers of the tribunal to amend or supplement the award) and Section 73 (which provides that a right to challenge may be lost if the wronged party does not make an objection on first becoming aware of the irregularity) of the AA.

The rationale behind these requirements is to ensure parties do not hold back their objections to the post-award stage, to try to obtain a tactical advantage if the award turns out not to be favourable.[52]

As the Singapore Court of Appeal has observed, ‘to countenance such hedging would be fundamentally unfair to the process itself, to the tribunal and to the other party’.[53]

Challenging enforcement for breach of due process

The New York Convention (the Convention),[54] which provides a framework for the recognition and enforcement of foreign arbitral awards in the 166 contracting states (at the time of writing), allows for a due process challenge to be brought at the enforcement stage.

It provides (at Article V(1)(b)) that ‘[r]ecognition or enforcement of the award may be refused’ if the award debtor ‘was not given proper notice of the appointment of the arbitrator or of the arbitration proceedings or was otherwise unable to present his case’. An equivalent provision is found in Article 36(1)(a)(ii) of the Model Law.

In most cases, a party with a due process complaint will be able to seek to set aside the award in the courts of the seat (and then resist enforcement under Article V(1)(e) of the Convention). However, the Convention drafters acknowledged that this would not always be the case (e.g., if the jurisdiction of the seat has no mechanism for annulment), and it was for that reason that Article V(1)(b) was necessary.[55]

In the England and Wales High Court decision in Malicorp v. Egypt, enforcement was refused on both grounds: not only had the award been set aside at the seat, but the tribunal’s decision to award damages on a basis for which the claimant had never argued ‘must have been a complete surprise to Egypt’ and constituted a ‘serious breach of natural justice’.[56]

Domestic courts applying Article V(1)(b) of the Convention have observed that the use of the word ‘may’ in its text confers a discretion as to whether or not to refuse recognition and enforcement on this basis, thus allowing for the application of tests similar to those applied in the set-aside context.

For example, the Supreme Court of Hong Kong has noted that one ‘could envisage circumstances where the court might exercise its discretion [to enforce the award], having found the ground established, if the Court were to conclude, having seen the new material which the defendant wished to put forward, that it would not affect the outcome of the dispute’.[57]

One example of a successful challenge to enforcement based on due process is the December 2020 decision of the Paris Court of Appeal in Al Misnad v. SEGQ.[58]

The Court refused under Article 1520 of the French Civil Procedure Code to enforce a US$26 million award on the basis that the tribunal’s decision to determine the seat of the arbitration outside Qatar and to substitute ad hoc for institutional proceedings without consulting the parties or allowing them to make submissions on the issue was a breach of due process, including on the basis of impartiality.

A striking feature of the case was the conviction of the three-member tribunal by a criminal court in Doha for participating in a scheme to cause intentional harm to the respondent (an uncle of the Emir of Qatar), a move that has been described as ‘unprecedented’[59] and widely condemned by the inter­ national arbitration community.

As discussed in relation to the set-aside stage, courts are generally alive to the distinction between a merely unwelcome procedural decision and a due process violation.

For example, in Gold Reserve Inc v. Bolivarian Republic of Venezuela,[60] the England and Wales High Court dismissed Venezuela’s attempt to resist enforcement on the basis that it had been unable to present its case in an ICSID Additional Facility proceeding because the division of hearing time was unequal, in circumstances where Venezuela had itself requested a condensed hearing and chosen not to cross-examine the claimant’s witnesses.

Conclusion

As was noted in the first edition of this chapter, an unfortunate trend in arbitration practice has seen parties attempting to use (or abuse) the essential safeguard of due process for tactical reasons.

The spectre of annulment or non-enforcement of an award for want of due process is raised by parties hoping to influence tribunals’ procedural decision-making in their favour (by triggering what is often referred to as ‘due process paranoia’), to delay or disrupt the proceedings or even to frustrate enforcement of the award.

If this type of manoeuvring is permitted to succeed, the costs of proceedings soar, timelines extend and confidence in the system is diminished.

Encouragingly, however, courts have generally proved unwilling to indulge such tactics. In most major arbitration jurisdictions, courts are respectful of tribunals’ procedural discretion and step in to police its exercise only when a true threat to the integrity of the process is detected.[61]

As one leading commentator has observed: ‘The courts have this (mostly) under control. If some tribunals still risk mismanaging proceedings because of “due process paranoia”, they are ignoring the ample reassurance and practical advice to be had.’[62]

Of particular current relevance, it is now clear that remote evidential hearings are an acceptable procedural option and, in many cases, can provide significant savings in both time and cost (not to mention reduced environmental impact) without any obvious effect on a tribunal’s ability properly to assess the evidence or arguments presented.

It is to be hoped that the appetite for virtual hearings does not dwindle as the covid-19 pandemic recedes.

Thus, some authorities refer to “due process” – a term which is often used, with particular legal meanings, in domestic legal systems – in international arbitration. The better approach is to avoid phrases which coincide with domestic procedural rules, instead referring neutrally to “procedural fairness”. ’
