Simon handles litigation before the Commercial and Admiralty Courts in London and before a number of London Arbitration Tribunals including in particular, the LMAA and LCIA. He also deals with soft commodity trade dispute cases before GAFTA and FOSFA Arbitration Tribunals and occasionally has been involved in international commercial arbitrations before the ICC.

Simon is frequently asked by leading insurers in the Japanese, Korean and European markets, to provide marine insurance coverage advice in respect of very high value losses, including those arising from major natural catastrophes and political disturbances. Simon has enormous expertise in claims arising out of the carriage of goods by sea, which have been at the heart of Simon's practice throughout his career, in particular representing marine insurers and trading companies in Japan.

Simon's cases include major casualties, total loss of vessel and cargo, charterparty disputes, general average, marine insurance coverage and trading/commodity contract problems particularly concerning soft commodities (soybeans, rice and sugar). In the course of the last 10-15 years Simon has handled a large number of piracy cases almost always representing the marine cargo insurance/cargo owner interest.

Simon is recognised by Legal 500 and Chambers & Partners as a recommended lawyer for shipping in London.
