He has worked under a variety of procedural rules, including ICC, UNCITRAL and LCIA Rules, as well as the rules of other less well-known arbitral bodies, such as ADCCAC.

He has been involved in a number of high-profile cases, most recently representing the successful appellant in the Court of Appeal in Bennett (Construction) -v- CIMC MBS Limited [2019] EWCA Civ 1515 (which expounded on the interrelationship of paragraphs 2, 4, 5 and 7 of the Scheme for Construction Contracts in the context of milestone payments).

As well as his experience in handling complex disputes (whether in litigation, arbitration or other forms of alternative dispute resolution), Jonathan has also been appointed as a party-appointed arbitrator to determine disputes under the LCIA and ICC Rules.
