Lord Hoffmann was a Lord of Appeal in Ordinary (Law Lord) from 1995 to 2009. Since then he has been appointed as an arbitrator in more than 100 international commercial and investment treaty disputes under the ICC, LCIA, ICSID, UNCITRAL, SIAC and KLRCA Arbitration Rules. He is ranked by Chambers 2015 among the “most in demand” international arbitrators global-wide with a “stellar reputation”.
Lord Hoffmann's judgments in Investors Compensation Scheme Ltd v West Bromwich Building Society 1 WLR 898 and Chartbrook v Persimmon Homes Ltd  AC 1101 are the leading general authorities in England and the Commonwealth on the interpretation of agreements. On the relationship between interpretation in domestic law and in international law, his judgment in R v Lyons  AC 976 has often been cited, most recently by the Court of Final Appeal in Hong Kong. (That case concerned the interpretation of an English statute using the same words as an international treaty). Cases in which he has given judgments on the application of international law as part of English law are R v Jones  AC 136 (on the incorporation of the international law on aggressive war) and Jones v Ministry of the Interior (Saudi Arabia)  1 AC 270 (on state immunity). Since 2009 Lord Hoffmann has been an arbitrator in numerous cases, some of which have raised questions of international law, and is at present the arbitrator appointed by the Government of Pakistan and by the Government of Albania in two arbitrations under an investment treaty and the Energy Charter respectively.
In the period since 2009 he has sat as an arbitrator in over sixty arbitral proceedings under the rules of the ICC, the LCIA and ICSID in disputes concerning commercial, property, intellectual property rights, private international law and public international law.
