Breakdown of the text by blocks.

Jurisdiction and introduction

The first articles set out the scope, definitions, rules on notification and computation of time limits. They then describe the request (articles 8 to 12) and the answer (articles 13 to 16), the content of which is detailed.

Article 6 specifies that the tribunal rules on its own jurisdiction, including on the existence or validity of the arbitration agreement. This competence-competence rule is essential: it prevents a party from blocking the procedure by challenging the clause.

Tribunal, procedure and evidence

Articles 17 to 28 organise the appointment of arbitrators, their independence and their challenge. Articles 29 to 42 deal with the conduct of the procedure: first meeting, timetable, briefs, interim measures, hearing, taking of evidence, experts.

Article 36 allows the tribunal to appoint an independent expert, after hearing the parties, and article 38 organises the production of documents according to rules inspired by international rules of evidence.

Award, costs and final provisions

Articles 43 to 52 concern the award: form, reasoning, sixty-day time limit, partial awards, consent awards, correction, finality. Articles 53 to 58 set the costs, the advance and the allocation.

The final provisions recall confidentiality, the limitation of liability of the arbitrators and the tribunal, and the rules for amending the Rules.

Annexes to the Rules

Annex I contains the scale of fees, Annex II the expedited procedure, Annex III the code of ethics, Annex IV the mediation rules and Annex V the urgent measures. They form an integral part of the Rules and apply on the same terms.

Each annex can be downloaded separately. A concordance table makes it quick to find the rule applicable to a given situation.
