Katie Sutton has extensive experience in the resolution of high-profile, complex and high-value cross-border disputes and investigations across a range of sectors, including the banking and finance, pharmaceutical, media, defence and energy industries. Ms. Sutton has experience in conducting arbitrations under the ICSID, LCIA and UNCITRAL Rules.

Recent notable arbitration and litigation experience includes advising:

  • the Republic of South Sudan in its oil sector negotiations and related international law issues following its secession from the Republic of Sudan, as well as in ICSID proceedings brought by Sudapet Co. Ltd. concerning the disputed ownership of significant oil field interests (disputed amount exceeding US$1 billion). Legal Business named Skadden as its 2017 International Arbitration Team of the Year for the defence of this case;
  • the Republic of South Sudan in the recovery of substantial sums representing the proceeds of shipments of crude oil misappropriated by the Republic of Sudan. For this work, Skadden was commended by the Financial Times in its 2013 “Innovative Lawyers” report for Europe and the firm also won the African Legal Awards’ “Dispute Resolution Team of the Year” award in 2013;
  • AAR (Alfa, Access & Renova) in its dispute with BP over the oil major’s attempt to form a US$16 billion strategic alliance with Rosneft, the state-owned Russian oil company, for the exploration of oil in the Arctic Circle. The dispute involved obtaining an emergency injunction blocking the deal in the High Court and subsequently obtaining an award from an arbitration tribunal seated in Stockholm that the deal was prohibited under the parties’ shareholders agreement. Both Global Arbitration Review and the Financial Times’ “Innovative Lawyers Report” recognised Skadden for our innovative role in this representation; and
  • an international investment bank in connection with disputes (in excess of US$1 billion) arising under structured finance products involving proceedings in London and New York.

Ms. Sutton also has conducted numerous multijurisdictional investigations related to U.N. and EU sanctions, anti-corruption and fraud, including investigations in the U.K., Italy, Russia, Ukraine, UAE and Denmark.

Prior to joining Skadden, Ms. Sutton practiced at a leading international law firm in Sydney, Australia, and taught contract law, criminal law and international human rights law at Queen Mary, the University of London.
