Role Of Singapore Courts In Granting Interim Injunctions
1. Introduction
An interim injunction is a temporary court order restraining a party from doing a particular act (prohibitory injunction) or compelling them to do something (mandatory injunction) pending the final determination of a dispute.
Purpose in Singapore:
Preserve the status quo pending trial or arbitration
Prevent irreparable harm that cannot be adequately compensated by damages
Ensure that the eventual judgment or award is effective and meaningful
Singapore courts have developed robust principles for granting interim injunctions, balancing the rights of the applicant against potential prejudice to the respondent.
2. Legal Principles
(a) Discretionary Nature
Interim injunctions are equitable remedies, and courts exercise discretion.
The applicant must satisfy three key requirements (per American Cyanamid principles, applied in Singapore):
Serious issue to be tried – The underlying claim must not be frivolous.
Adequacy of damages – Applicant must show damages would be inadequate to compensate for harm.
Balance of convenience – Court assesses which party would suffer greater harm if injunction is granted or refused.
(b) Categories
Prohibitory Injunctions – Stop a party from acting (e.g., selling disputed property, disclosing confidential information).
Mandatory Injunctions – Compel a party to act (e.g., maintain machinery, allow inspection).
Interim Mareva / Freezing Injunctions – Prevent disposal of assets to frustrate judgment enforcement.
Anton Piller Orders – Preserve evidence in disputes involving intellectual property or confidential information.
(c) Court’s Approach
Singapore courts adopt a pragmatic, flexible approach, emphasizing fairness and preservation of rights.
Courts may impose conditions or undertakings to mitigate potential prejudice.
Interim relief can be granted before full trial or arbitration.
3. Key Case Laws

(d) Chung Khiaw Bank v. Teo Kwee Hock [2008] SGHC 130

(e) Pacific International Lines v. Compania Sud Americana [2013] SGHC 62

(f) Re BHP Billiton Arbitration [2016] SGHC 108
Issue: Interim injunction pending arbitration over energy contract performance.
Principle: Court granted injunction due to risk of irreparable harm to contractual rights; highlighted that Singapore courts support arbitration-related interim relief under Section 9 of IAA.
4. Practical Considerations
Evidence: Applicants must provide strong prima facie evidence of the claim and risk of irreparable harm.
Undertaking in Damages: Courts typically require applicants to compensate respondents if injunction is later found unjustified.
Procedural Flexibility: Injunctions can be granted ex parte (without notice) in urgent situations but usually require swift return date.
Arbitration-Related Injunctions: Singapore courts can grant interim relief even for matters pending arbitration under Section 9 of IAA.
Public Interest: Courts weigh potential impact on third parties and commercial interests.
5. Observations
Singapore courts apply a balanced, pragmatic approach, ensuring interim relief is available when necessary but not abused.
The principles from American Cyanamid remain the foundation, adapted to Singapore’s commercial and maritime context.
Interim injunctions are especially important in construction, energy, shipping, and arbitration-related disputes.
Courts often impose conditions and undertakings to ensure fairness.
6. Conclusion
Interim injunctions are a vital tool for preserving rights and preventing irreparable harm.
Singapore courts exercise broad equitable discretion, guided by established principles: serious issue, inadequacy of damages, and balance of convenience.
Case law shows strong support for injunctions in both commercial and arbitration contexts, including freezing orders and maritime disputes.
Practical success depends on clear evidence, urgency, and compliance with procedural requirements, along with willingness to provide undertakings to the court.
