In a striking legal development, the English courts have drawn a firm line against foreign interference in arbitration agreements governed by English law. Tecnimont S.p.A. and MT Russia LLC recently achieved a significant victory by securing anti-suit relief from the English High Court (Butcher J), effectively halting Russian court proceedings initiated by LLC EuroChem North-West-2. These Russian proceedings, brought under Article 248 of the Russian Arbitration Procedural Code, were designed to block an ongoing English arbitration. The twist? They were filed after the English Court had already determined earlier this year that EuroChem North-West-2 was under the control of Russian businessman Mr. Melnichenko.
Faced with this cross-border legal tug-of-war, Tecnimont and MT Russia turned to the arbitral tribunal, which issued peremptory orders instructing EuroChem North-West-2 to refrain from continuing the Russian action. When those orders failed to bring compliance, the claimants escalated the matter to the English court under section 42 of the Arbitration Act 1996—a provision that allows courts to enforce arbitral tribunal directives. EuroChem North-West-2 responded with two dramatic counterarguments: first, that English courts lacked the authority to issue anti-suit injunctions under section 42; and second, that its director could face criminal charges in Russia for disobeying the Russian court’s directives. Both claims, however, were decisively rejected by the English judge.
Here’s the part that breaks new ground: Legal commentators believe this is the first time an English court has used section 42 of the Arbitration Act 1996 to grant an anti-suit injunction. This decision not only reinforces the primacy of arbitration agreements but also raises fascinating questions about the limits of judicial cooperation between jurisdictions—especially in politically or economically charged contexts like Russia.
The case also highlights a growing tension between international arbitration obligations and domestic legislative measures designed to assert national authority. Should a national court penalize parties for complying with arbitration agreements made under another country’s laws? Or does this kind of judicial conflict risk undercutting the foundation of international commerce and cross-border dispute resolution?
Representing the successful arbitration claimants, including Tecnimont S.p.A., were Alan Maclean KC and Tom Leary, both from Blackstone Chambers.

And here’s the controversial question to you: Was the English court right to take such a bold stance against Russian proceedings, or does this risk deepening the clash between national sovereignty and international arbitration? Share your thoughts—this legal debate is only just beginning.
