CJEU’s first ruling on the conformity of asymmetric jurisdiction clauses with the Brussels I recast regulation and the 2007 Lugano Convention
by Guillaume Croisant, Claudia Cavicchioli, Nicole Rölike, Alexia Kaztaridou, and Julie Esquenazi (all Linklaters)
In a nutshell: reinforced legal certainty but questions remain
In its decision of yesterday (27 February 2025) in the Lastre case (Case C-537/23), the Court of Justice of the European Union (CJEU) handed down its long-awaited first judgment on the conformity of asymmetric jurisdiction clauses with the Brussels I recast regulation and the 2007 Lugano Convention.
The Court ruled that the validity of asymmetric jurisdiction clauses is assessed in the light of the autonomous rules of Article 25 of the regulation (rather than Member States’ national laws) and confirmed their validity where the clause can be interpreted as designating courts of EU or Lugano States.
This decision dispels some of the previous uncertainties, particularly arising from the shifting case law of the French Supreme Court. The details of the decision and any possible impact, in particular the requirement for the clause to be interpreted as designating courts of EU or Lugano States, will need to be analysed more closely, but on the whole the CJEU strengthened foreseeability and consistency regarding unilateral jurisdiction clauses under the Brussels I regulation and the Lugano convention.
Besides other sectors, this decision is of particular relevance in international financing transactions, including syndicated loans and capital markets, where asymmetric jurisdiction clauses in favour of the finance parties have been a long-standing practice.
Going International: The SICC in Frontier Holdings
By Sanjitha Ravi, Jindal Global Law School, OP Jindal Global University, Sonipat, India
The Singapore International Commercial Court (“SICC”) in Frontier Holdings Ltd v. Petroleum Exploration (Pvt) Ltd overturned a jurisdictional ruling by an International Chamber of Commerce (“ICC”) arbitral tribunal, holding that the tribunal did, in fact, have jurisdiction to hear the dispute. The SICC’s decision focused on interpreting the arbitration provisions in the Petroleum Concession Agreements (“PCAs”) and Joint Operating Agreements (“JOAs”), which had created ambiguity regarding whether disputes between foreign parties, i.e., Foreign Working Interest Owners (“FWIOs”), and Pakistan parties, i.e., Pakistani Working Interest Owners (“PWIOs”), were subject to international arbitration. The arbitral tribunal, by majority, had concluded the PCAs restricted ICC arbitration to disputes between FWIOs inter se or between FWIOs and the President of Pakistan, thereby excluding disputes between FWIOs and PWIOs. The SICC rejected this reasoning and concluded that the provisions should be applied with necessary modifications to fit the JOAs’ context by conducting an in-depth construction of the dispute resolution provisions of the different agreements involved. The court found that a reasonable interpretation of these provisions indicated an intention to submit FWIO-PWIO disputes to ICC arbitration rather than Pakistani domestic arbitration. Read more
Enforcing Foreign Judgments in Egypt: A Critical Examination of Two Recent Egyptian Supreme Court Cases
I. Introduction
The recognition and enforcement of foreign judgments in the MENA region can sometimes be challenging, as it often involves navigating complex legal frameworks (domestic law v. conventions). In addition, case law in this field has encountered difficulties in articulating the applicable guiding principles and is sometimes ambiguous, inconsistent, or even contradictory. Two recent decisions rendered by the Egyptian Supreme Court highlight this issue, alhoutgh – it must be admitted – the Court did provide some welcome clarifications. In any event, the cases reported here highlight some key issues in the recognition and enforcement of foreign judgment and offer valuable insights into the evolving landscape of this area of law in Egypt.

“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.
