Emergency arbitration is a mechanism which "allows a disputing party to apply for urgent interim relief before an arbitration tribunal has been formally constituted".¹

Although several arbitral institutions have adopted specific rules for emergency arbitration in the field of international commercial arbitration, - see e.g. the ICC Rules (2017 and 2021),² the LCIA Rules (2014 and 2020),³ and the HKIAC Rules (2018)⁴ - the spread of such mechanism to the field of investment arbitration remains quite confidential to date. For instance, neither the ICSID Arbitration Rules, nor the UNCITRAL Arbitration Rules contain provisions for the appointment of an emergency arbitrator.

This being said, the SCC Rules (2017),⁵ the SIAC Investment Rules (2017),⁶ and the CIETAC International Investment Arbitration Rules (2017),⁷ all contain provisions for the appointment of an emergency arbitrator that apply to investment arbitration proceedings.

The provisions on emergency arbitration in the SCC Rules (2017) do not distinguish between commercial and investment arbitration, and parties choosing to arbitrate under the SCC Rules are deemed to have agreed on the SCC Rules in force on the date of the filing of an application for the appointment of an emergency arbitrator.⁸

The corresponding provisions in the SIAC Investment Rules (2017) require the express consent of both parties to apply.⁹ Although worded differently, the same also seems to be true for the CIETAC International Investment Arbitration Rules (2017).¹⁰

The procedure to be followed under these three sets of rules is broadly similar. The appointment of an emergency arbitrator follows the filing, by the requesting party, of a written request to that end to the arbitral institution.¹¹

Once appointed, the emergency arbitrator enjoys broad powers to conduct the proceedings,¹² and is expected to render its decision in a matter of days,¹³ or weeks at the latest.¹⁴ The lex arbitri can also be considered to determine the scope of the emergency arbitrator’s powers.¹⁵

To date, five decisions by emergency arbitrators appointed under the SCC Rules in investment arbitration cases have been published.¹⁶ Other unpublished decisions rendered under the SCC Rules have been reported,¹⁷ as well as a decision rendered under the ICC rules,¹⁸ while no decision under the SIAC or CIETAC Rules have been reported.

In assessing whether the emergency relief sought should be granted, emergency arbitrators appointed under the SCC Rules have referred to various criteria,¹⁹ which include:

• Prima facie jurisdiction of the tribunal;²⁰
• Prima facie case on the merits;²¹
• Risk of irreparable/imminent harm;²²
• Urgency;²³
• Proportionality of the measures sought.²⁴

Some tribunals have also discussed the necessity of the measures sought.²⁵

The standard for awarding interim relief is raised when the emergency arbitrator is asked to deal with host State’s actions linked to its sovereign power, such as when taking tax measures.²⁶ (See also Taxes and Provisional Measures)  

Emergency arbitrators appointed under the SCC Rules have had to determine whether the State-parties to the applicable International Investment Agreement (IIA) could be found to have given their consent to the application of emergency arbitration provisions, although the version of the SCC rules applicable at the time of the conclusion of these instruments did not contain such provisions.²⁷

So far, emergency arbitrators, upon interpretation of the SCC Rules, have found in the affirmative.²⁸

Emergency arbitrators appointed under the SCC Rules have also had to determine whether they had jurisdiction to grant emergency measures, although the cooling-off period prescribed by the applicable IIA had not elapsed.²⁹

There again, emergency arbitrators have so far held that this does not prevent an application for emergency relief from being made.³⁰

The question whether the emergency arbitrator can allocate costs for the emergency proceedings is debated.³¹

The decision of an emergency decision is binding on the parties,³² but may be amended or revoked at the request of a party by the emergency arbitrator itself,³³ or by the arbitral tribunal once appointed.³⁴

Although the decision of the emergency arbitrator may take the form of an order or an award,³⁵ it remains uncertain whether it can, in the latter case, be enforced as such under the New-York Convention.³⁶
