Effect Of Unilateral Option Clauses
1. Nature of Unilateral Option Clauses
A typical clause may state:
“All disputes shall be referred to arbitration, except that Party A may elect to bring proceedings before courts.”
Thus:
One party (usually lender/investor) → multiple options
Other party → restricted to arbitration
2. Legal Issues Involved
(a) Equality of Parties
Arbitration is based on procedural equality, raising concerns when one party has superior rights.
(b) Mutuality of Obligation
Some jurisdictions require reciprocity in dispute resolution agreements.
(c) Certainty of Agreement
Courts examine whether such clauses create uncertainty or ambiguity.
(d) Public Policy Concerns
Clauses may be challenged as:
Unfair
Oppressive
Contrary to justice
3. Validity Across Jurisdictions
(a) Generally Enforced (Pro-Arbitration Jurisdictions)
England
Singapore
India (increasingly pro-enforcement)
(b) Restricted or Invalidated
France (earlier approach)
Some civil law jurisdictions
4. Key Case Laws (At Least 6)
(1) Pittalis v Sherefettin
Principle: Validity of unilateral arbitration clauses.
Court upheld a clause allowing one party to choose arbitration.
Confirmed that lack of mutuality does not invalidate arbitration agreement.
(2) NB Three Shipping Ltd v Harebell Shipping Ltd
Principle: Enforceability of asymmetric clauses.
Court enforced a unilateral option clause in commercial shipping context.
Emphasized commercial practicality and party autonomy.
(3) Mauritius Commercial Bank Ltd v Hestia Holdings Ltd
Principle: One-sided clauses are valid if clearly drafted.
Upheld lender’s exclusive option to litigate.
Reinforced importance of certainty and clarity.
(4) Bharat Aluminium Co v Kaiser Aluminium Technical Services Inc
Principle: Party autonomy in arbitration.
Though not directly on unilateral clauses, it strongly supports freedom of parties to structure arbitration agreements, indirectly supporting such clauses.
(5) Emirates Trading Agency LLC v Prime Mineral Exports Pvt Ltd
Principle: Enforcement of contractual dispute mechanisms.
Court upheld contractual dispute clauses emphasizing party intent, which extends to asymmetric clauses.
(6) Rusoro Mining Ltd v Venezuela
Principle: Investor protection and dispute choice flexibility.
Highlighted legitimacy of giving investors flexible dispute resolution options.
(7) Rothschild & Co Bank AG v Comité de Défense des Obligataires
Principle: Invalidity in French law (earlier approach).
Court struck down unilateral jurisdiction clause as potestative (dependent solely on one party’s will).
Reflected civil law skepticism toward asymmetry.
5. Indian Position
Indian courts generally:
Favor party autonomy
Enforce arbitration agreements unless:
They are unconscionable
They violate public policy
Although no direct Supreme Court ruling squarely on unilateral clauses, trends suggest:
Increasing acceptance
Alignment with international practice
6. Advantages of Unilateral Option Clauses
(a) Commercial Flexibility
Lenders/investors can choose favorable forum
(b) Risk Management
Allows stronger party to secure enforcement-friendly jurisdiction
(c) Efficiency
Avoids rigid dispute resolution mechanisms
7. Criticisms and Risks
(a) Inequality
One party enjoys procedural advantage
(b) Enforcement Risks
May be invalid in some jurisdictions
(c) Jurisdictional Challenges
Disputes over validity delay proceedings
8. Drafting Considerations
To enhance enforceability:
Use clear and precise language
Avoid ambiguity in:
Scope of option
Timing of exercise
Ensure clause does not appear:
Arbitrary
Oppressive
Align with:
Governing law
Seat of arbitration
9. Interaction with Enforcement Regime
Awards based on unilateral clauses are generally enforceable under the
New York Convention, unless:
Clause is invalid under governing law
It violates public policy of enforcement forum
10. Conclusion
Unilateral option clauses reflect a tension between party autonomy and procedural fairness. While widely upheld in pro-arbitration jurisdictions like the UK and increasingly India, they remain controversial in certain civil law systems. The modern trend favors enforcement, provided the clause is clearly drafted, commercially justified, and not unconscionable.
