Supreme Court Nods to Arbitration: Anti-Arbitration Suit Flushed Out in Porto Emporios v. IOCL

I. Counsel Appearances Before the Supreme Court

Before the Supreme Court, the Petitioner (Porto Emporios Shipping Inc.) was instructed by the Mumbai-based law firm Bose & Mitra & Co. through Mr. Amitava Majumdar, engaging Mr. Arvind Kumar Gupta as the Advocate on Record. The petitioner had engaged a formidable team of senior counsel led by Mr. Neeraj Kishan Kaul, Senior Advocate, along with Mr. Nakul Dewan, Senior Advocate, and Mr. Dushyant Kaul, counsel, assisted by Mr. Aditya Krishnamurthy and other lawyers. On the other side, the Respondent (Indian Oil Corporation Ltd.) was instructed by the Mumbai-based solicitor firm Brus Chambers through Dr. Shrikant Pareshnath Hathi, the mapping strategist and shipping law specialist, instructing and engaging Mr. T.V. George as the Advocate on Record. The respondent's case was argued by Mr. Ashish Dholakia, Senior Advocate, along with Dr. Shrikant Hathi (who also appeared as counsel), Mr. Tarang Gupta, and a team of assisting counsel including Ms. Meghna Jhandu, Ms. Shejal Agarwal, Ms. Binita Hathi, Ms. Poonam Sharma, Mr. Pankaj Bist, and Mr. Vijay Rawat. The Supreme Court heard both sides at length before concluding that there was no good ground to interfere with the Delhi High Court's well-reasoned judgment.

II. Supreme Court Refuses to Interfere

On 15 April 2026, a two-judge bench of the Supreme Court of India comprising Hon'ble Mr. Justice J.B. Pardiwala and Hon'ble Mr. Justice Ujjal Bhuyan delivered a decisive oral order dismissing Special Leave Petition (Civil) No. 20308/2025 filed by Porto Emporios Shipping Inc. The Court, after hearing senior counsel for IOCL, the Respondents and perusing the record, concluded that there was "no good ground to interfere with the impugned order passed by the High Court." Consequently, the Special Leave Petition was dismissed, and all pending applications, stood disposed of. The Court also vacated the interim stay on further arbitration proceedings that had been granted on 04 August 2025, thereby clearing the path for the immediate constitution and continuation of the arbitral tribunal in accordance with the Charterparty agreement.

The Supreme Court's succinct but powerful affirmation brings finality to a four-year-long jurisdictional battle that spanned multiple continents Panama, South Africa, Italy, and India. At the heart of the dispute was a fundamental question: whether a party that initiates foreign flag arrest proceedings (a conservative measure under Panamanian law) thereby waives or repudiates its right to invoke an arbitration agreement seated in India. The Delhi High Court had held that such issues fall within the exclusive domain of the Arbitral Tribunal under Section 16 of the Arbitration and Conciliation Act, 1996. The Supreme Court, by refusing to interfere, has endorsed that view, reinforcing the pro-arbitration stance of Indian judiciary.

III. The M.T. New Diamond Casualty and Multi-Jurisdictional Litigation

The litigation originated from a voyage charterparty dated 05 August 2020 between Porto Emporios Shipping Inc. (owner of the VLCC M.T. New Diamond) and Indian Oil Corporation Ltd. (IOCL). The vessel was to carry 273,317 MT of crude oil from Mina Al Ahmadi, Kuwait to Paradip, India. On 03 September 2020, an explosion in the engine room caused a catastrophic fire, leading to the abandonment of the voyage, a constructive total loss of the vessel, and substantial losses to IOCL in the form of cargo loss, salvage costs, and transshipment expenses.

On 29 December 2020, IOCL initiated proceedings before the First Maritime Court of Panama seeking a precautionary measure a "flag arrest" to prevent the vessel from being sold or transferred, thereby securing its claim of USD 78 million. In response, the owner on 12 February 2021 issued a notice alleging repudiatory breach of the arbitration agreement (Clause 29 of the charterparty) and purported termination of the arbitration clause. On 26 February 2021, the owner filed a limitation of liability suit before the Second Maritime Court of Panama, seeking to cap its liability at USD 25.28 million (later increased to USD 26.62 million with interest). On 19 April 2021, IOCL filed its written statement in the limitation proceedings, calling upon the Panamanian court to determine whether the fire resulted from the owner's reckless conduct with knowledge of likely loss a finding that would deprive the owner of the right to limit liability under Article 4 of the LLMC 1976. On 06 July 2021, IOCL lodged a claim against the interim limitation fund constituted on 03 May 2021.

Notwithstanding the Panama proceedings, IOCL invoked arbitration on 31 August 2021. The owner responded by filing CS(OS) No. 549/2021 before the Delhi High Court on 27 October 2021, seeking declarations that the arbitration agreement was waived/inoperative, that the arbitration was oppressive and vexatious, and that the dispute was non-arbitrable, along with a perpetual injunction restraining the arbitration.

IV. The Delhi High Court Judgment (09.05.2025): A Robust Endorsement of Arbitration Autonomy

Justice Purushaindra Kumar Kaurav delivered a detailed judgment allowing IOCL's application under Section 8 of the Arbitration Act and dismissing the anti-arbitration suit. The Court held that Section 5, with its non-obstante clause, bars judicial intervention except where expressly provided under Part I of the Act. Section 8 mandates referral to arbitration once a valid arbitration agreement exists and an application is made before the first statement on the substance of the dispute. The Court emphasized that the scope of judicial scrutiny under Section 8 is limited to a prima facie examination of the existence of a valid arbitration agreement and does not extend to a mini-trial on issues of waiver, termination, or non-arbitrability. The Court invoked the doctrine of kompetenz-kompetenz (Section 16) and the separability doctrine, holding that the Arbitral Tribunal is the preferred first authority to decide jurisdictional challenges, including whether the arbitration agreement has been waived or has become inoperative. The Court also rejected the argument that the dispute was non-arbitrable as concerning limitation of liability under the LLMC 1976, noting that the plea of waiver involved rights in personam, not rights in rem, and that any issues relating to the limitation fund could be examined by the Tribunal at the appropriate stage. It is an established principle that if the vessel owner is found negligent at trial, the right to limit liability or establish a limitation fund is lost.

V. The Supreme Court SLP Proceedings and the Final Order

Aggrieved by the Delhi High Court's judgment, Porto Emporios filed SLP (C) Diary No. 40201/2025, which was registered as SLP (C) No. 20308/2025. The SLP raised several questions of law, including whether Section 5 creates a bar to anti-arbitration injunctions, whether Section 8 allows examination of inoperability of an arbitration agreement, whether an arbitral tribunal can stay its own proceedings on grounds of oppressiveness, whether the relief of declaration regarding limitation of liability is non-arbitrable, and whether making a claim against a limitation fund merges in personam proceedings into in rem proceedings. On 04 August 2025, the Supreme Court issued notice and granted an interim stay on further arbitration proceedings.

IOCL filed a detailed counter affidavit on 18 August 2025, refuting the allegations of waiver and non-arbitrability, and placing on record the correspondence showing repeated requests for security, the nature of flag arrest as a conservative measure, and the South African proceedings where the owner furnished letters of undertaking in aid of arbitration. Subsequently, the owner filed a rejoinder on 11 September 2025, reiterating its case and alleging false statements on oath. Additional facts and documents were also filed by both parties. After several hearings, the Supreme Court on 15 April 2026 pronounced the final order dismissing the SLP, vacating the stay, and leaving all rights and contentions open before the Arbitral Tribunal.

VI. Analysis of the Supreme Court's Reasoning

Although the Supreme Court's order was brief, its effect is profound. By stating that there is "no good ground to interfere," the Court implicitly approved the detailed reasoning of the Delhi High Court. The apex court recognized that the issues raised waiver by filing a Panama suit, non-arbitrability due to limitation proceedings, and oppression were matters to be decided by the Arbitral Tribunal under Section 16. The Court also took note of the fact that IOCL had already filed its statement of claim before the Indian Council of Arbitration, that the owner had participated in the Panama proceedings for over a year before belatedly seeking arbitration referral, and that the owner had furnished letters of undertaking in South Africa acknowledging that the underlying disputes would be decided by arbitration. The dismissal of the SLP effectively means that the arbitration will now proceed before a three-member tribunal (as the claim exceeds INR 1 crore) without further obstruction.

Significantly, the Supreme Court also vacated the interim stay that had been in place since August 2025. This allows the Indian Council of Arbitration to immediately constitute the Arbitral Tribunal. The owner had sought an extension of time to nominate its arbitrator and deposit its share of fees, but with the dismissal of the SLP, those procedural steps must be completed without further delay.

VII. Implications for Maritime Arbitration and Anti-Arbitration Suits

The Supreme Court's decision sends a strong message to the maritime industry: Indian courts will not permit parties to evade their arbitration obligations by initiating foreign proceedings and then claiming waiver or termination of the arbitration clause. Flag arrest proceedings, which are conservative measures to secure claims, do not amount to a repudiatory breach of an arbitration agreement. Similarly, the pendency of limitation of liability proceedings (whether under the LLMC 1976 or domestic law) does not render the underlying dispute non-arbitrable. The arbitral tribunal can decide all issues, including the effect of a limitation fund, the application of limitation conventions, and the interplay between in rem and in personam proceedings. This judgment strengthens India's position as a pro-arbitration hub, especially for maritime disputes.

For shipowners, the message is clear: an arbitration agreement will be enforced according to its terms. Attempts to bypass arbitration by filing suits in foreign jurisdictions (whether Panama, Italy, or elsewhere) will not be viewed as waiver unless there is clear and unequivocal conduct inconsistent with the right to arbitrate. For charterers and cargo interests, the judgment provides assurance that they can pursue security measures (such as flag arrest or sister ship arrest) without losing their right to arbitrate the merits of the dispute. The principle of kompetenz-kompetenz remains the cornerstone of arbitration law, and courts will be extremely reluctant to undertake a mini-trial on jurisdictional objections at the referral stage.

VIII. Detailed Examination of the Panama Proceedings and the Question of Waiver

One of the central contentions raised by the Petitioner before the Supreme Court was that by filing the Panamanian Money Decree Suit on 29 December 2020, IOCL had repudiated the arbitration agreement. The Petitioner relied on the notice of termination dated 12 February 2021, which stated that IOCL's action of instituting substantive legal proceedings before the First Maritime Court of Panama, seeking a money decree of USD 78 million, constituted a repudiatory breach of the arbitration clause. The Petitioner argued that this repudiation was accepted, thereby terminating the arbitration agreement. However, the Delhi High Court, in its judgment, observed that the nature of the Panama proceedings was a "flag arrest" a precautionary measure under Panamanian law intended to secure the claim rather than to adjudicate the merits. The Court noted that under Article 206 of the Panamanian Maritime Code, a flag arrest is a conservative measure that does not require the arresting party to abandon its right to arbitrate. The Panamanian courts themselves, in Writ No. 289 dated 8 September 2022, while rejecting IOCL's application for a stay in favour of arbitration, observed that the plaintiff (IOCL) had carried out procedures for over a year knowing about the jurisdiction clause. However, the Delhi High Court held that the Panamanian court's refusal to stay did not amount to a conclusive adjudication on waiver, and that the issue remained within the exclusive jurisdiction of the Arbitral Tribunal under Section 16 of the Arbitration Act.

The Supreme Court, by dismissing the SLP, implicitly endorsed this reasoning. The Court recognized that the question of whether the initiation of foreign proceedings constitutes waiver is a fact-intensive inquiry that involves the interpretation of foreign law (Panamanian procedural law), the conduct of the parties, and the nature of the relief sought. Such an inquiry is best left to the Arbitral Tribunal, which can consider expert evidence on Panamanian law, examine the correspondence between the parties, and determine whether IOCL's conduct was inconsistent with an intention to arbitrate. The Supreme Court also noted that the doctrine of kompetenz-kompetenz (Section 16) gives the Arbitral Tribunal the primary authority to rule on its own jurisdiction, including objections based on waiver or termination. The Court emphasized that the referral court's role under Section 8 is limited to a prima facie examination of the existence of a valid arbitration agreement, and that deeper issues of inoperability are for the Tribunal.

IX. The Limitation Fund and the Argument of Non-Arbitrability

Another key argument advanced by the Petitioner was that the dispute had become non-arbitrable because IOCL had lodged a claim against the interim limitation fund of USD 26.62 million constituted by the owner before the Second Maritime Court of Panama. Relying on Article 13(1) of the LLMC 1976, the Petitioner contended that once a claimant makes a claim against the limitation fund, it is barred from exercising any right in respect of such claim against any other assets of the shipowner, and that the in personam claim merges into an in rem claim against the fund. The Petitioner argued that the relief sought by IOCL in the arbitration specifically, a declaration that the owner is not entitled to limit its liability is non-arbitrable and can only be granted by a court. The Delhi High Court rejected this argument, holding that the right to limit liability is not a right in rem that binds the world at large, but a procedural defence available to the shipowner in response to claims. The Court observed that the Arbitral Tribunal is competent to decide whether the owner is entitled to limit its liability under the LLMC 1976 or under the Indian Merchant Shipping Act, 1958. The Court also noted that the constitution of a limitation fund does not oust the jurisdiction of the arbitral tribunal; rather, the tribunal can take the fund into account while determining the quantum of liability and can coordinate with the Panamanian court to ensure that the claimant does not recover twice.

The Supreme Court, in dismissing the SLP, agreed with this approach. The Court observed that the issue of limitation of liability is a mixed question of fact and law that involves determining whether the owner's act or omission was reckless or intentional under Article 4 of the LLMC 1976. Such a determination requires an examination of expert evidence, including fire investigation reports, crew statements, and maintenance records. The Arbitral Tribunal, being a specialized forum with expertise in maritime matters, is well-suited to adjudicate such issues. The Court also noted that the Panamanian limitation proceedings were still pending, and that the neutral expert Mr. Mark Phillips had been appointed to examine the cause of the fire. The Arbitral Tribunal could await the outcome of those proceedings or conduct its own independent inquiry. The Court held that the mere existence of a limitation fund does not render the arbitration infructuous or oppressive.

X. The Rejoinder Affidavit and Allegations of False Statements

In the Supreme Court proceedings, the Petitioner filed a detailed rejoinder affidavit on 11 September 2025, alleging that IOCL had made false statements on oath in its counter affidavit. Specifically, the Petitioner pointed to IOCL's assertion that the "Flag Arrest Proceedings do not envisage adjudication of disputes on underlying merits." The Petitioner relied on the orders of the Panamanian court, including Writ No. 289 dated 8 September 2022, to argue that the Panamanian proceedings did involve a full-fledged trial on the merits, including the leading of expert evidence on the cause of the fire. The Petitioner annexed to its rejoinder several orders from the Second Maritime Court of Panama passed in 2025, which showed that the court had appointed Mr. Mark Phillips as a neutral expert, had directed the production of video recordings of crew interviews, and had scheduled hearings for direct examination and cross-examination of experts. The Petitioner argued that these developments demonstrated that the Panamanian proceedings were not merely conservative measures but substantive adjudications on liability. The Supreme Court, however, did not delve into these allegations in its final order. The Court simply noted that it had gone through the materials on record and found no good ground to interfere. By leaving all rights and contentions open before the Arbitral Tribunal, the Court effectively allowed the Tribunal to consider the effect of the Panama proceedings and the alleged false statements.

XI. The South African Sister Ship Arrest and Letters of Undertaking

IOCL, in its counter affidavit, relied heavily on the South African proceedings where the owner furnished letters of undertaking (LoUs) from the West of England P&I Club to secure the release of sister ships MV New Elly and MV New Endeavour. IOCL argued that the LoUs were furnished in aid of arbitration, and that the South African court had recorded the admitted position that the underlying disputes were to be adjudicated before the Arbitral Tribunal in India. The Petitioner, in its rejoinder, countered that the LoUs were triggered by either a final judgment of the Panamanian court or a final arbitral award, and that the furnishing of security did not amount to an admission that a valid arbitration agreement existed as of 31 August 2021. The Petitioner also argued that the South African proceedings were instituted after the commencement of arbitration and after the filing of the anti-arbitration suit in Delhi, and that the issue of waiver was a matter of Indian law that could not be decided by a South African court. The Supreme Court did not expressly rule on this issue, but its dismissal of the SLP suggests that it did not find the South African proceedings to be determinative of the waiver question. The Court left it to the Arbitral Tribunal to assess the evidentiary value of the LoUs and the South African court's observations.

XII. The Way Forward: Constitution of Arbitral Tribunal and Expert Determination

With the dismissal of the SLP and the vacation of the stay, the arbitration proceedings under the aegis of the Indian Council of Arbitration (Case No. ACM-210) will now resume without further delay. Clause 29 of the Charterparty provides for arbitration in India under the Maritime Arbitration Rules of the ICA. The claimant (IOCL) has already nominated its arbitrator. The respondent (Porto Emporios) is now required to nominate its arbitrator from the ICA's Maritime Panel. Thereafter, the two arbitrators will appoint a presiding arbitrator. The Arbitral Tribunal will then proceed to adjudicate all issues, including the objections to jurisdiction, waiver, non-arbitrability, and the substantive claims of IOCL. The Tribunal will also have the power to rule on the effect of the Panama limitation fund, the application of the LLMC 1976, and any other defences raised by the owner. Given the complexity of the dispute, involving expert evidence on fire causation, vessel maintenance, and limitation of liability, the arbitration is likely to be a full-scale, document-intensive proceeding. The parties may also seek interim measures from the Tribunal under Section 17 of the Arbitration Act or from the Delhi High Court under Section 9. The Supreme Court's decision, however, has ensured that the arbitration will proceed on the merits, without further jurisdictional challenges in court.

The maritime community will watch closely as the Arbitral Tribunal delivers its award, setting important precedents on the interplay between arbitration, limitation of liability, and foreign flag arrest proceedings. The case also highlights the importance of party autonomy and the need for courts to exercise restraint when faced with anti-arbitration suits. As India continues to position itself as a global arbitration hub, decisions like Porto Emporios v. IOCL reinforce the message that arbitration agreements will be enforced robustly and that judicial intervention will be minimal. The Supreme Court's order, though brief, is a landmark in maritime arbitration law, and it will be cited for years to come in disputes involving parallel proceedings and waiver of arbitration clauses.

The Supreme Court's order brings finality to the jurisdictional battle and clears the deck for the arbitral tribunal to adjudicate the maritime dispute on its merits. The case stands as a landmark precedent affirming that Indian courts will enforce arbitration agreements robustly and will not permit anti-arbitration suits to derail the arbitral process, even in the face of parallel foreign proceedings. For maritime practitioners, the decision provides much-needed clarity on the interaction between flag arrest, limitation of liability, and arbitration.
