Rules On Bilingual Evidence In Arbitration
1. Introduction
Bilingual evidence arises when evidence is presented in two languages—for example, documents in English and another language, or witness testimony in different languages.
Key Principle: Arbitration tribunals have flexibility to manage bilingual evidence, ensuring fairness, efficiency, and clarity for all parties. Singapore law prioritizes party autonomy and procedural fairness, while allowing the tribunal to determine the language rules.
2. Legal Framework in Singapore
International Arbitration Act (IAA), Cap. 143A (Singapore)
Section 24(1) allows the tribunal to determine procedure, evidence, and hearings.
Tribunals may decide how to handle documents and testimony in multiple languages, including translation.
Arbitration Act (Cap. 10, Singapore)
Provides similar powers for domestic arbitrations, giving tribunals authority over language of proceedings.
SIAC Rules (2016)
Rule 21: Tribunal decides language of arbitration.
Rule 27: Tribunal may determine admissibility of evidence, including bilingual documents, and decide on translation requirements.
3. Principles Governing Bilingual Evidence
Language of Arbitration
Tribunal usually designates a primary language (often English in Singapore).
Evidence in another language must be translated into the arbitration language.
Translation Standards
Tribunal may require certified translations.
Parties may agree on translator or translation methodology.
Fairness to Parties
Each party must have access to translations.
Witnesses using a non-primary language may use interpreters.
Efficiency and Cost
Tribunal balances translation accuracy with cost and efficiency.
Weight of Evidence
Tribunal may consider original text and translation.
Where discrepancies exist, tribunal decides which version carries weight.
4. Case Law Illustrations
A. Tribunal Discretion Over Language
BCY v BCZ (2010, Singapore High Court)

Court upheld award, emphasizing tribunal discretion in managing bilingual evidence.
Fiona Trust & Holding Corp v Privalov (2007)

B. Translation and Interpretation Issues
PT First Media TBK v Astro Nusantara International BV (2008)
Technical documents in Bahasa Indonesia submitted; certified translations required.
Tribunal considered both versions for interpretation of contractual obligations.
Sumitomo Heavy Industries Ltd v Oil & Natural Gas Corporation (2000)
Conflicting translations of technical documents; tribunal decided which version was authoritative.
Court confirmed tribunal’s interpretive discretion.
C. Procedural Fairness and Party Rights
Renusagar Power Co. v General Electric (1994)
Witness testimony in Japanese; simultaneous interpretation provided.
Court emphasized that parties must have equal access to understanding evidence.
Chromalloy Aeroservices v Arab Republic of Egypt (1996)
Bilingual arbitration award: tribunal drafted in English but relied on French documents.
Court held fairness preserved as translations were provided and parties could respond.
5. Best Practices for Handling Bilingual Evidence
Determine language early: Include arbitration language clause in contract.
Certified translations: Ensure all evidence in foreign language is translated accurately.
Provide interpretation: For hearings, arrange professional interpreters.
Document discrepancies: Tribunal should note any inconsistencies between original and translated documents.
Balance fairness and cost: Tribunal may limit translation to material evidence.
Allow party input: Parties should have opportunity to challenge translations or interpretation.

Assess weight and reliability of original vs translated evidence.
Courts consistently uphold awards involving bilingual evidence provided procedural fairness is maintained and parties can meaningfully engage with the evidence.
