UNCITRAL Model Law and International Arbitration Institutions

Updated 11 October 2026 · Fact-checked

The UNCITRAL Model Law is a template arbitration statute that countries can adopt. India's Arbitration and Conciliation Act, 1996 is based on it. Institutions such as ICC, LCIA, SIAC and ICA administer arbitrations under their own rules. In exams, link the Model Law to the Act's sections and explain each institution's role.

Understand UNCITRAL Model Law and International Arbitration Institutions

UNCITRAL is the United Nations Commission on International Trade Law. It prepares model texts to harmonise trade law across countries. A model law is not a treaty. No country is bound to it. A country picks it up and enacts it, with changes, as its own statute.

The UNCITRAL Model Law on International Commercial Arbitration (1985) is one such text. It gives a ready, balanced framework: the arbitration agreement, appointment and challenge of arbitrators, tribunal jurisdiction, conduct of proceedings, the award, and limited grounds to set it aside. India drew on it when it enacted the Arbitration and Conciliation Act, 1996, which also draws on the UNCITRAL Conciliation Rules. Part I of the Act is the domestic and general part. Part II deals with enforcement of foreign awards.

The UNCITRAL Arbitration Rules are different. They are procedural rules that parties can choose for an ad hoc arbitration, where no institution runs the case. The Model Law is a statute for states. The Rules are a contract-level choice for parties. Do not mix them up.

An arbitral institution administers arbitrations. It does not decide the dispute. It supplies rules, helps appoint arbitrators, decides challenges, fixes fees and often scrutinises awards. Well-known ones are the ICC (International Chamber of Commerce, Paris), the LCIA (London Court of International Arbitration), the SIAC (Singapore International Arbitration Centre) and the ICA (Indian Council of Arbitration). ICA is India's institution, set up to promote arbitration in trade disputes.

The Act respects party choice. Under section 2(8), an agreement of the parties includes any arbitration rules referred to in that agreement. So if the clause names ICC or SIAC rules, those rules form part of the parties' agreement. Section 2(6) also lets parties authorise an institution to decide an issue they are free to settle, except under section 28.

Key rules to remember

Model Law influence: UNCITRAL Model Law (template) → enacted with changes → Arbitration and Conciliation Act, 1996; The Model Law is not binding. The Act is the law that applies in India.
Institutional rules form part of the agreement: Section 2(8): agreement of parties includes any arbitration rules referred to in that agreement; A clause choosing ICC, LCIA, SIAC or ICA rules brings those rules in.
Party freedom to authorise an institution: Section 2(6): freedom to determine an issue includes the right to authorise any person, including an institution, to determine it (except section 28); Substance of the dispute under section 28 cannot be handed to an institution this way.
Applicability of Part I: Section 2(2): Part I applies where the place of arbitration is in India; Sections 9, 27 and 37(1)(a), 37(3) also apply to international commercial arbitration seated abroad, unless parties agree otherwise.
Law applicable to substance, seat in India: Section 28(1)(a): not international commercial arbitration → substantive law in force in India; 28(1)(b): international commercial arbitration → rules of law designated by parties; If parties designate no law, the tribunal applies the rules of law it considers appropriate.
Model Law vs Rules: Model Law = statute for states; UNCITRAL Rules = procedural rules chosen by parties; Useful for a one-line distinction in answers.

How to solve UNCITRAL Model Law and International Arbitration Institutions questions

Use this method for any written question on the Model Law, the Act or the institutions.

1Identify what is asked: the Model Law, the UNCITRAL Rules, an institution, or the link to the Act.
2State what the instrument is and its legal nature: a model statute, a set of rules, or an administering body.
3Link it to the Act. Name the relevant provision, such as section 2(8), 2(6), 2(2) or 28, only where you are sure of it.
4Apply the facts: check the seat, whether the arbitration is international commercial, and what rules the clause names.
5Explain the institution's role: appointing arbitrators, administering the case, fixing fees, scrutinising the award.
6Conclude clearly: which law or rules govern and what the parties or the institution may do.

Quickest way: Three-question check

When to use it: Use when time is short and the question gives a clause naming an institution or the Model Law.

Where is the seat? If India, Part I applies (section 2(2)).
Is it international commercial arbitration under section 2(1)(f)? This decides how section 28 operates.
What rules does the clause name? Under section 2(8) they become part of the agreement. Then write the institution's role in two lines.

Common mistakes in UNCITRAL Model Law and International Arbitration Institutions

Saying the Model Law is binding on India or is itself Indian law.
Students hear that the Act is 'based on' it and assume it applies directly.
Fix: Write that the Model Law is only a template. The Act is the binding statute.
Confusing the Model Law with the UNCITRAL Arbitration Rules.
Both carry the UNCITRAL name.
Fix: Model Law is for legislators. The Rules are chosen by parties, often for ad hoc cases.
Saying an arbitral institution decides the dispute.
Institution names such as 'Court of Arbitration' suggest a court.
Fix: The tribunal decides. The institution administers, appoints, and applies its rules.
Treating institutional rules as separate from the arbitration agreement.
Students forget section 2(8).
Fix: Cite section 2(8): the agreement includes any rules it refers to.
Applying domestic substantive law to every arbitration seated in India.
Students skip the split in section 28(1).
Fix: Only non-international arbitrations seated in India follow Indian substantive law. International commercial arbitrations follow the parties' designated rules of law.

Worked examples

Example 1

Explain how the UNCITRAL Model Law relates to the Arbitration and Conciliation Act, 1996, and distinguish it from the UNCITRAL Arbitration Rules.

Show the solution

State the nature: the Model Law (1985) is a template statute prepared by UNCITRAL. No country is bound to adopt it.
Link to India: the Act, 1996 draws on it, with Indian modifications. Part I covers arbitration generally and Part II covers enforcement of foreign awards.
State the Rules: the UNCITRAL Arbitration Rules are procedural rules that parties may choose by agreement, usually for ad hoc arbitration.
Show the legal route for the Rules: under section 2(8), an agreement of the parties includes any arbitration rules referred to in it.
Conclude the distinction: the Model Law guides legislators, while the Rules operate by party choice.

Answer: The Model Law is a non-binding template on which the 1996 Act is based. The UNCITRAL Rules are party-chosen procedural rules that become part of the agreement under section 2(8).

Example 2

Alpha Ltd (Mumbai) and Beta Pte Ltd (Singapore) have a supply contract. The clause says: 'Disputes shall be settled by arbitration under SIAC rules, seat Mumbai. Governing law of the contract is the law of Singapore.' Advise on the role of SIAC and the law applicable to the substance of the dispute.

Show the solution

Classify: Beta is a body corporate incorporated outside India, so under section 2(1)(f)(ii) the arbitration is an international commercial arbitration, assuming the relationship is commercial.
Seat: the place of arbitration is Mumbai, so under section 2(2) Part I applies.
Institution: SIAC rules are referred to in the agreement, so under section 2(8) they form part of the agreement. SIAC administers the case and applies its rules, including on appointment of arbitrators. It does not decide the merits.
Substance: under section 28(1)(b)(i), the tribunal decides in accordance with the rules of law designated by the parties.
Designation of Singapore law: under section 28(1)(b)(ii), unless otherwise expressed, this refers to Singapore's substantive law and not its conflict of laws rules.
Add: under section 28(3), the tribunal must take into account the contract terms and applicable trade usages.

Answer: SIAC administers the arbitration under its rules, which form part of the agreement. Part I of the Act applies as the seat is Mumbai. The tribunal applies Singapore's substantive law to the dispute, taking contract terms and trade usages into account.

Exam tips

Write one clear line on the Model Law's non-binding nature. Examiners look for it.
In case-based questions, always classify the arbitration first: seat, then international commercial or not.
For institutions, give a role list: rules, appointment, administration, fees, award scrutiny. Avoid claiming details of fee schedules or case counts.
Cite sections 2(2), 2(6), 2(8) and 28 where they fit, and quote them accurately.
Close with a one-sentence conclusion that answers the facts.

Practice questions from International Law of Arbitration

UNCITRAL Model Law and International Arbitration Institutions: frequently asked questions

What is the difference between the Model Law and UNCITRAL Rules?

The Model Law is a template statute for countries to adopt. The UNCITRAL Arbitration Rules are procedural rules that parties choose by agreement, often for ad hoc arbitration.

Can parties choose ICC, LCIA or SIAC rules for an arbitration seated in India?

Yes. Under section 2(8), an agreement of the parties includes any arbitration rules referred to in it. Part I still applies because the place of arbitration is in India.

Does an arbitral institution decide the dispute?

No. The arbitral tribunal decides. The institution administers the proceedings under its rules, for example by helping with appointments and fixing fees.
