The judicial conflict between the UK and Russia has markedly
intensified due to a surge in anti-suit injunctions (ASIs), anti-antisuit
injunctions (AASIs), and anti-enforcement injunctions (AEIs). This friction was
exacerbated by Russia’s 2020 Federal Law No. 171-FZ, which expanded the
jurisdiction of Russian courts over disputes involving sanctioned Russian
entities.
This article examines the jurisdictional divide created by
these legislative changes, the conflicting approaches of English and Russian
courts, and the enforcement challenges that have emerged. It also explores
Russian courts’ growing tendency to assert exclusive jurisdiction over disputes
involving sanctioned parties, even where arbitration clauses exist, and contrasts
this with the UK judiciary’s firm stance in upholding arbitration agreements
through ASIs, AASIs, and AEIs.
