Citation: [2023] EWHC 3135 (Comm)
Judgment on


The High Court’s decision in The Shell Petroleum Development Company of Nigeria Limited v Sunlink Energies and Resources Limited [2023] EWHC 3135 (Comm) illuminates several pertinent legal principles pertaining to anti-suit injunctions, arbitration agreements, and costs in the context of international commercial law. This article offers an analysis of the court’s judgment, underlining the legal reasoning behind the ruling.

Key Facts

The claim by The Shell Petroleum Development Company of Nigeria Limited (the Claimant) centered around an anti-suit injunction against Sunlink Energies and Resources Limited (the Defendant), following the latter’s initiation of proceedings in Nigerian court notwithstanding an extant arbitration agreement stipulating London as the arbitration venue. The Defendant had challenged the court’s jurisdiction and contested the anti-suit injunction but subsequently withdrew the challenge, advancing no opposition to the Claimant’s assertions.

Anti-Suit Injunctions and Arbitration Agreements

The judgment reasserts the English court’s authority to enforce arbitration agreements through anti-suit injunctions, as outlined in the Supreme Court’s decision in Enka v Chubb [2021] WLR 4117. The court expressed no hesitation in recognizing that the parties were subject to a binding obligation to arbitrate disputes as per their contract, irrespective of the Defendant’s unfounded justifications to avoid arbitration.

The principle that governs is the respect for the parties’ agreement as to the dispute resolution mechanism chosen - arbitration in this case, with London specifically designated as the seat of arbitration by the ICC, underpinning that the parties’ commercial intent should be honored absent a compelling and legitimate reason to litigate.

Jurisdiction and Service of Proceedings

In assessing the court’s jurisdiction, the judgment confirms that proper service had been executed under the previously authorized methods, and with the Defendant not pursuing its challenge under CPR Part 11, the court deemed itself “duly seised of the matter.” This underscores the court’s deference to established procedural compliance in determining jurisdiction.

Awarding of Costs

The judgment provides for the assessment of costs, leaning on indemnity principles for their basis. Indicative to the commercial significance of the arbitrated dispute, the court demonstrated flexibility paralleled with circumspection in the summarily assessment of costs, citing SM Production Corp v Gaz du Cameroun SA [2023] EWHC 2820 (Comm).

Mandatory Relief

The mandatory nature of relief granted by the court, requiring the Defendant to discontinue the Nigerian proceedings, reflects an approach to ensure both compliance with the arbitration agreement and cessation of the Defendant’s breach of such agreement, underscoring the assertive role courts may take in enforcing arbitration clauses.


The court granted a final anti-suit injunction against the Defendant, obligating it to cease legal action in Nigeria and comply with the arbitration proceedings as originally agreed. The Defendant was ordered to bear the costs of the proceedings, awarded on an indemnity basis, and the Claimant’s success in costs was quantified summarily at $490,000, reflective of the urgency and complexity of the proceedings.


The Shell Petroleum Development Company of Nigeria Limited v Sunlink Energies and Resources Limited echoes the judiciary’s intention to faithfully uphold commercial arbitration agreements and highlights the constraints on national courts when international arbitration is a contractual obligation. The recognition of jurisdiction, effective service of proceedings, and pragmatic approach to costs together affirm the court’s role in international commercial disputes, underlying its support for efficient and effective dispute resolution avenues as chosen by the parties themselves.
