Opinion of AG de la Tour in C-713/23, Trojan: A step forward in the cross-border recognition of same-sex marriages in the EU?
Dr. Carlos Santaló Goris, Postdoctoral researcher at the University of Luxembourg, offers an analysis of the Opinion of Advocate General de la Tour in CJEU, Case C-713/23, Trojan
From Coman to Trojan
On 5 June 2018, the Court of Justice of the European Union (‘CJEU’) rendered its judgment in the case C-673/16, Coman. In this landmark ruling, the CJEU decided that Member States are required to recognize same-sex marriage contracted in another Member Stated to grant a residence permit to the non-EU citizen spouse of an EU citizen under the EU Citizens’ Rights Directive. The pending case C-713/23, Trojan goes a step further than C-673/16, Coman. On this occasion, the CJEU was asked whether EU law requires a civil registry of Poland, a Member State that does not provide any form of recognition to same-sex couples, to transcribe the certificate of same-sex marriage validly contracted in another Member State. A positive answer would imply that the same-sex marriage established under German law would be able to deploy the same effects as a validly contracted marriage under Polish law. While the CJEU has not yet rendered a judgment, on 3 April 2025, Advocate General de la Tour issued his Opinion on the case. While the CJEU might decide differently from AG de la Tour, the Opinion already gives an idea of the solution that might potentially be reached by the CJEU. This post aims to analyse the case and explore its implications should the CJEU side with AG de la Tour. Read more
A New Precedent in Contract Conflicts: Decoding the Tyson v. GIC Ruling on Hierarchy Clauses
By Ryan Joseph, final-year BBA LLB (Hons) student, Jindal Global Law School, India.
Introduction
The recent decision of the UK High Court (“Court”) in Tyson International Company Limited (“Tyson”) v. General Insurance Corporation of India (“GIC”) sets a critical precedent for cases that lie at the intersection of arbitration, contractual hierarchy, and judicial intervention through anti-suit injunctions. The principal issue in the case revolved around the harmonious application of two conflicting dispute resolution clauses contained in two separate agreements pertaining to the same transaction. While one provided for dispute settlement through arbitration seated in New York, the other was an exclusive jurisdiction clause that provided for dispute settlement by England and Wales courts. To resolve this apparent conflict between the two clauses, the Court relied on a confusion clause (also known as a hierarchy clause) in the parties’ agreement to rule that the exclusive jurisdiction clause, in favour of England and Wales courts, prevails over the arbitration clause. Based on this conclusion, the Court issued an anti-suit injunction against GIC from arbitrating the dispute in New York. Read more
Australian Federal Court Backs India on Sovereign Immunity: Another Twist in the Devas v. India Saga
by Shantanu Kanade, Assistant Professor, Dispute Resolution, Jindal Global Law School, India
The Federal Court of Australia (“Federal Court”), in its recent judgement in the Republic of India v. CCDM Holdings, LLC[1] (“Judgement”), held that the Republic of India (“India”) was entitled to jurisdictional immunity from Australian Courts in proceedings seeking recognition and enforcement of foreign arbitral awards dealing with disputes arising from ‘non-commercial’ legal relationships. The Court’s judgment was rendered with respect to an appeal filed by India against an interlocutory judgement of a primary judge of the same court, rejecting India’s sovereign immunity claim.
Background of the Dispute
Three Mauritian entities of the Devas group (“Original Applicants”) had commenced arbitration proceedings in 2012 under the 1998 India-Mauritius BIT, impugning India’s actions with respect to an agreement for leasing of space spectrum capacity entered between Devas Multimedia Private Limited (an Indian company in which the Original Applicants held shares) and Antrix Corporation Limited (an Indian state-owned entity). In 2011, India’s Cabinet Committee on Security decided to annul the said agreement, citing an increased demand for allocation of spectrum towards meeting various military and public utility needs (“Annulment”). The arbitration proceedings that followed culminated in a jurisdiction and merits award in 2016[2] and a quantum award in 2020 (“Quantum Award”)[3]. The Original Applicants have since sought to enforce the Quantum Award against India in different jurisdictions, discussed here.[4]

Virtual Workshop (in English) on September 2, 2025: Eva Lein on “PIL and dispute resolution in times of crisis”

On Tuesday, September 2, 2025, the Hamburg Max Planck Institute will host its monthly virtual workshop Current Research in Private International Law at 11:00 a.m. – 12:30 p.m. (CEST). Professor Eva Lein (Lausanne University) will speak, in English, about the topic
“PIL and dispute resolution in times of crisis”
In times of polycrisis, the law is put to the challenge. In international commercial transactions the question is how law can safeguard commercial activity, avoid a plethora of disputes, and encourage a pragmatic legal environment conducive to global economic recovery. This contribution discusses how dispute settlement mechanisms and private international law can be used to responsibly manage disputes in this context and to appropriately respond to future crises.
The presentation will be followed by open discussion. All are welcome. More information and sign-up here.

UEMATSU on Cross-border Patent Litigation and Lis Alibi Pendens: A Korean–Japanese Case Study for Future Asian Principles of Private International Law

The latest issue of the Ritsumeikan Law Review (No. 43, 2025), a law review in English published by the Ritsumeikan University Law Association since 1986, features a study by Professor Mao UEMATSU (School of Law, Ritsumeikan University) entitled Cross-border Patent Litigation and Lis Alibi Pendens: A Korean–Japanese Case Study for Future Asian Principles of Private International Law.
The article examines a series of patent litigation cases in Korea and Japan, analyzing them to “illustrate the complexity of cross-border patent litigation.” It further argues that, even after reforms to procedural laws in both Korea and Japan, structurally similar cross-border conflicts remain unresolved. The paper concludes with preliminary reflections on possible improvements in legal coordination within Asia.
By introducing case law from both jurisdictions and sharing information on recent legal developments in the region, the study provides valuable material for comparative research and contributes to a better understanding of the dynamics of Asian private international law.
The paper is freely available at the Ritsumeikan Law Review online version here.
