Sanctions and International Arbitration

We are grateful to our speakers for giving up their time. Despite having to compete with Wimbledon, Brickcourtchambers soiree at the Sky Garden (oh to be on that guest list), and other summer events, the room was packed.

The speakers took us through recent developments in sanctions and Arbitration (arbitrability, enforcement and conduct).


Maya Lester KC

Took us through the framework, how sanctions as foreign policy tools have increased, and been drawn up rapidly, and come thick and fast regarding Russia.

UK Brexit phenomenon.

Difficulties in knowing who is subject to sanctions. Also legal uncertainties re payment.

Took us through a case from Jersey

OWH SE i.L v RTI Ltd [2025] JRC 137


Marina Tarnovskaia

Went through LCIA statistics, and the difficulties that arise when part way through a hearing one party is subject to sanctions.
“The main sanctions regimes which are invoked: the UK, the USA, the EU, Switzerland and Canada.
In respect of the UK, LCIA applied the General Licence and the Arbitration Costs General Licence in more than 80 arbitrations. The Licence works well so the procedural impact of the UK sanctions is rather minimal. We have not seen instances where a candidate arbitrator rejected to accept the appointment due to the UK sanctions. There could be a delay in payment and a corresponding request to extend the procedural deadlines (or vacate a hearing) but it is not a frequent situation. Sometimes it is tactical.
So far we have not seen any case which goes beyond the cap afforded by the General Licence.”

Spoke about anti-suit and anti anti-suit injunctions

UniCredit bank Gmbh v RusChem Alliance LLC [2025] EWCA Civ99

(CIArb London branch hopes to explore the views held across La Manche in a future seminar).

This area is evolving, and the above a simple snapshot of a very detailed and informative seminar.
