Alexander Milner KC has a broad practice covering both commercial litigation and international arbitration.
Described in directories as “brilliant in every respect” and “a Rolls-Royce choice for all cases”, he is recommended in the fields of commercial dispute resolution, international arbitration, aviation, banking and finance and civil fraud. He was named ‘Commercial Litigation Junior of the Year’ at the Chambers Bar Awards in 2021, before being appointed silk the following year.
A Russian speaker, he has appeared in many of the largest disputes to emerge from Russia and other ex-Soviet states, including Berezovsky v Abramovich, BTA Bank v Ablyazov, Mezhprombank v Pugachev and Bank St Petersburg v Arkhangelsky (where the trial judge praised his “very effective” cross-examination). He has also participated in numerous major arbitrations, including claims between Gazprom and Naftogaz of Ukraine where the sums in dispute exceeded $100 billion.
His cases often involve the law of Russia and other post-Soviet countries, and he has extensive experience of conflicts of law and jurisdictional disputes, as well as cases involving economic sanctions. He frequently makes and defends applications for injunctive relief.
His aviation practice includes all types of leasing, aircraft financing and regulatory matters, including those relating to airport slots. He is currently acting for lessors in a $300 million claim against reinsurers arising out of the Russian invasion of Ukraine, and for an airline in a complex financing dispute raising novel issues under the Cape Town Convention.
Alexander sits as an arbitrator and has been appointed to numerous tribunals in London, Singapore and Moscow. He is an empanelled arbitrator at the BVI International Arbitration Centre, the Hong Kong International Arbitration Centre, the Korean Commercial Arbitration Board in Seoul and the Asian International Arbitration Centre in Kuala Lumpur, and the Dubai International Arbitration Centre.
