Ecuador v Occidental Exploration and Production Company

Factual and Procedural Background

This application concerns the English law doctrine of "non-justiciability," which holds that municipal courts of England and Wales lack competence to adjudicate rights arising from transactions between independent sovereign states under international law. The issue arises from an arbitration award dated 1 July 2004, made by a tribunal of three arbitrators following arbitration between Company A and State A under UNCITRAL rules with the seat in London.

State A challenged the award under section 67(1) of the Arbitration Act 1996, alleging that the arbitrators exceeded their jurisdiction and seeking to set aside the award. Company A contended that the non-justiciability doctrine prevents the English court from determining this challenge, as the arbitration and award arose from a Bilateral Investment Treaty ("BIT") between the USA and State A dated 27 August 1993.

Company A filed an application seeking dismissal of State A's challenge on the ground of non-justiciability. This was the first time an arbitration award pursuant to a BIT was brought before the English courts.

Company A is a Californian corporation engaged in oil exploration in State A since 1985. Under a 1999 contract with a state-owned corporation of State A, Company A obtained exclusive rights to explore and exploit oil in a specified region. Company A bore exploration costs and received a percentage of oil produced, determined by a formula known as "Factor X."

Company A paid VAT on local and imported purchases related to oil production and sought refunds from State A's tax authority, which were initially granted but later denied by resolutions in 2001-2003. State A argued VAT refunds were unavailable as the exported crude oil was not a "manufactured" product under its tax law.

Company A filed lawsuits in State A's tax courts challenging the denial of VAT refunds as unlawful under State A's tax law. After abandoning further refund claims, Company A initiated arbitration under the BIT, alleging breaches of State A's obligations under the BIT and international law.

The BIT is a treaty between two states designed to encourage investment by granting investors standing to pursue disputes directly against a state through arbitration. It includes provisions for fair and equitable treatment, protection against expropriation, and access to binding international arbitration without first resorting to domestic courts.

Company A invoked arbitration procedures under the BIT in 2002, nominating arbitrators, with the arbitration seat ultimately fixed in London. State A raised jurisdictional objections, which the tribunal joined with the merits. The award was issued in July 2004.

The tribunal rejected State A's jurisdictional objections, holding that Company A had preserved its rights in domestic courts on non-contractual issues while pursuing treaty-based claims in arbitration, that the dispute fell within the BIT's scope including tax matters related to the investment agreement, and that the expropriation claim was inadmissible.

On the merits, the tribunal found that VAT refunds were not included in Factor X, that Company A was entitled to VAT refunds under State A's law and regional law, and that State A breached its BIT obligations by denying refunds and failing to accord fair and equitable treatment. Damages and interest exceeding US$75 million were awarded to Company A.

State A challenged the award on grounds including excess jurisdiction and procedural irregularities. The non-justiciability argument was raised only in relation to the jurisdictional challenge.

Legal Issues Presented

1. Whether the English court has jurisdiction to entertain State A's challenge to the arbitral tribunal's substantive jurisdiction under section 67 of the Arbitration Act 1996, given the doctrine of non-justiciability.
2. Whether the doctrine of non-justiciability prevents the English court from interpreting and applying provisions of an international treaty (the BIT) between two foreign states that has not been incorporated into English municipal law.

Arguments of the Parties

Company A's Arguments

• The court would need to rehear jurisdictional issues afresh, interpreting the BIT, its negotiating history, and related international materials without the presence of the USA, a party to the BIT, which raises concerns about judicial competence and fairness.
• The English courts are reluctant to adjudicate on rights and obligations of foreign states not party to the proceedings and lack judicial or manageable standards for such matters, invoking the doctrine of non-justiciability as enunciated by Lord Wilberforce and Lord Oliver in leading cases.
• English courts should not interpret treaties not incorporated into domestic law, as per the Tin Council case, and the Arbitration Act 1996 is subject to the common law principle of non-justiciability.
• Interpreting the BIT would require ruling on international law transactions between sovereign states, which is non-justiciable.
• The arbitration agreement and substantive rights arise under international law, not municipal law, so the court should decline jurisdiction.

State A's Arguments

• The BIT is a treaty governed by public international law but is not incorporated into UK municipal law; nonetheless, this does not render the matter non-justiciable before the English court.
• The BIT expressly provides for disputes between investors and state parties to be resolved by arbitration in states party to the New York Convention, with the English court supervising the arbitral process as the seat is London.
• The arbitration agreement is a "standing offer" by the state party that an investor may accept, creating a relationship subject to municipal law procedural rules, namely the Arbitration Act 1996.
• English courts have precedent for interpreting unincorporated treaties when necessary to determine domestic rights, citing cases such as Dallal v Bank Mellat and CND v The Prime Minister.
• The rights asserted by Company A are private law rights enforceable in municipal courts, not rights exercised on behalf of a foreign state, and the court must consider jurisdictional challenges to ensure enforceability of awards under the New York Convention.
• Refusing jurisdiction would conflict with the statutory rights under the Arbitration Act 1996 and the enforcement regime of the New York Convention.

Court's Reasoning and Analysis

The court recognised that the BIT is an international treaty between sovereign states creating rights and obligations under public international law. However, the BIT also grants investors, who are municipal law entities, rights to pursue binding arbitration against a state party, with the arbitration procedure subject to municipal law (the Arbitration Act 1996) because the seat is London.

The court analysed whether the non-justiciability doctrine prevents it from adjudicating on State A's challenge to the tribunal's jurisdiction under section 67. It noted that while the court would need to interpret an unincorporated treaty, the challenge arises from a domestic statutory right to review arbitral jurisdiction, which creates a "foothold" in municipal law.

The court distinguished this case from the Tin Council case, where the claimants had no municipal rights against the states. Here, Company A has rights enforceable under municipal law through arbitration and the court's supervisory jurisdiction. The arbitration agreement itself is governed by public international law but is exercised through a municipal law procedural framework.

The court considered precedents allowing courts to interpret international treaties when necessary to determine domestic rights, such as Dallal v Bank Mellat and CND v The Prime Minister, confirming that non-justiciability is not an absolute bar.

The court rejected Company A's argument that the non-justiciability principle should prevent the court from exercising jurisdiction under section 67, noting that such an interpretation would undermine the statutory scheme for arbitration supervision and enforcement of awards under the New York Convention.

Practical difficulties of interpreting the BIT without the USA as a party were acknowledged but deemed not decisive, as the dispute resolution mechanism contemplated such circumstances. The court also noted that the BIT provides other mechanisms for resolving disputes between the states themselves.

Accordingly, the court held that the doctrine of non-justiciability does not prevent it from entertaining State A's challenge to the tribunal's jurisdiction under section 67 of the Arbitration Act 1996.

Holding and Implications

The court's final decision is to DISMISS Company A's application seeking to strike out State A's challenge to the tribunal's jurisdiction under section 67 of the Arbitration Act 1996.

This means the English court confirms its jurisdiction to consider challenges to arbitral tribunal jurisdiction arising from BIT arbitrations seated in England, notwithstanding the doctrine of non-justiciability concerning unincorporated treaties between sovereign states. The decision affirms the supervisory role of English courts under the Arbitration Act 1996 and supports enforcement and review mechanisms for international arbitration awards under the New York Convention.

No new precedent altering the doctrine of non-justiciability was established beyond its application in the context of BIT arbitration and municipal law procedural rights.
