The conference officially began with a detailed panel discussion on “Unsettled Legal Doctrines<\/span>” namely, Iura Novit Curia<\/span>, Precedent<\/span> and Res Judicata<\/span> in international commercial arbitration.<\/p>\n

The panel was moderated by Mr. Kevin Nash<\/span>, Director General, LCIA, London, and empanelled by esteemed professionals namely, Dr. Alexander Milionis<\/span>, Attorney, Niedermüller, Lichtenstein; Ms. Eleni Lentziou<\/span>, Senior Associate, CGA, Nicosia; Mr. Christodoulos Christodoulou<\/span>, Senior Associate, Chrysostomides Advocates, Nicosia; Mr. Kyriakos Pittas<\/span>, Partner, Soteris Pittas, Limassol.<\/p>\n

In the second part of the panel discussion, Mr. Christodoulos Christodoulou<\/span> and Mr. Kyriakos Pittas<\/span> delved into the applicability and relevance of precedent and res judicata in arbitration.<\/p>\n

Panel 1: Unsettled Legal Doctrines — Precedent and Res Judicata<\/span><\/p>\n

Introducing the topic, Mr. Kevin Nash<\/span> noted that while arbitration generally does not recognize binding judicial precedent, prior court judgments still matter through doctrines such as res judicata<\/span>, public policy considerations, and enforcement challenges.<\/p>\n

Mr. Kyriakos Pittas<\/p>\n

At the outset, Mr. Pittas began by emphasizing that arbitral tribunals are structurally independent from national court systems and are not part of a hierarchical judicial framework. Consequently, arbitration generally does not recognize binding precedents in the traditional judicial sense. However, he stressed that arbitration is not isolated from national legal systems, rather tribunals are indirectly constrained by external legal orders, particularly through the doctrine of res judicata<\/span>, public policy considerations, and judicial review during enforcement. Therefore, the debate is therefore less about judicial authority and more about “finality and legal effect.”<\/p>\n

Res Judicata in International Arbitration:<\/h3>\n

Mr. Pittas explained that res judicata<\/span> is widely recognized internationally as a mechanism to ensure the finality of judgments. While national courts typically apply their own domestic law to determine the scope of res judicata<\/span>, arbitration presents a more complex scenario because tribunals operate across multiple legal systems simultaneously, and the rules governing may vary considerably. This creates a “conflict of laws problem,” where the central issue is not whether res judicata applies, but rather which legal system governs the scope and effect of the doctrine.<\/p>\n

He added that in international arbitration, the determination of “conflict of rules” that apply to res judicata<\/span> depends on whether the doctrine<\/span> is classified as a substantive matter or a procedural one.<\/p>\n

Means of Applicability:<\/h3>\n

Referring to the recommendations issued by the International Law Association in its 72nd<\/span> Conference (2006), which proposed treating the positive effect of the prior judgment as substantive and the negative effect as procedural. However, he argued that this distinction was unpredictable because the positive effect of the res judicata might have procedural or substantive nature depending on the content.<\/p>\n

He further argued against the viability of both approaches. Neither the comparative law approach wherein different national laws are compared to determine the generally accepted res judicata<\/span> principles, nor the recognition approach wherein an international arbitrator examines whether the prior court judgment in question is capable of being recognized at the seat of arbitration.<\/p>\n

Thereafter, Mr. Pittas mentioned a suggested “transnational conflict of laws rule,” under which tribunals would apply the res judicata<\/span> rules of a prior judgment under such rules of law agreed upon by the parties, or in the absence of such agreement, the tribunal shall apply the law of that State where the prior judgment was issued. He stated that this approach aimed to enhance predictability, respect national legal systems, and avoid complex characterization disputes.<\/p>\n

Nevertheless, he cautioned that such an approach may:<\/p>\n
