Abstract Courts in England ordinarily grant anti-suit injunctions when proceedings are (or will soon be) initiated in a foreign court in breach of clauses which subject disputes to the exclusive jurisdiction of courts, or refer them to arbitration, in England. Would they, however, grant such relief in support of foreign dispute-resolution clauses? In UniCredit Bank v RusChemAlliance , the Supreme Court of the United Kingdom answered this question in the affirmative, thus expanding the English courts’ power to issue anti-suit injunctions. This article seeks to assess the likely extent of this expansion and the future implications it could have for the law on anti-suit injunctions in England. The article also examines the Supreme Court’s pronouncements on the other significant issue in the case concerning the law governing arbitration agreements and their potential effect following the enactment of the Arbitration Act 2025.
