Overview
Commercially minded and practical solutions are key drivers in Jonathan’s disputes practice. He strives to find the most cost-effective and sensible resolutions for his clients and firmly believes that a firm grasp of each client’s aims, paired with a good working relationship form a strong foundation for developing appropriate dispute resolution strategies and achieving results.
This could entail seeking a commercial settlement through negotiation and mediation or opting for a more formal resolution by way of litigation or arbitration. There is no fixed agenda and each matter is assessed on its own merits and with each client’s strategic goals and objectives in mind.
In this regard, Jonathan’s dispute resolution expertise and offering is broad. He is a qualified mediator with South African and United Kingdom qualifications who also specialises in High Court litigation and private arbitration, both internationally and domestically.
He has expertise in transactional disputes, contractual claims, mining-related litigation, class action lawsuits and urgent High Court proceedings. He has also worked on arbitrations seated in Johannesburg, Paris, London and Mauritius facing tribunals convened under the auspices of the ICC, the LCIA and AFSA.
Working alongside colleagues as local counsel to an International Law Firm, Jonathan received the following feedback:
‘He provided a timely, well considered, clearly presented, excellent memo on a question of South African contract law. He was also a delight to interact with.’- Elliot Friedman (Partner, Freshfields Bruckhaus Deringer LLP, New York).
An international client has also described working with Jonathan in the following terms:
‘Jonathan is diligent and proactive in his approach to work. His drafting is very clear and he is obviously able to grasp complex issues quickly.’
Currently, Jonathan is representing a multinational vehicle manufacturer in its ongoing class action lawsuit, which is breaking new ground in South Africa.
Jonathan has also recently been working on cross-border matters in Mauritius, Germany and the UAE, either as lead counsel or as local counsel instructed by international law firms.
Jonathan joined the firm straight out of university. He became a partner in 2022.
