Keystone Law adds arbitration partners

London-based law firm Keystone Law has appointed Clyde & Co partners Milena Szuniewicz-Wenzel and Ian Hopkinson to strengthen its international arbitration practice.

Milena advises on high-value, multi-jurisdictional disputes, acting for states, national energy companies and multinational corporates. 

Her work spans energy, telecommunications, trade and infrastructure, with particular expertise in production sharing agreements within the oil and gas sector.

Milena said: “Keystone’s dynamic model and strong disputes bench provide an excellent base for practice and aligns with the needs of energy and cross‑border arbitration clients. 

“I’m excited to join a team that embraces innovative ways of delivering strategic advice.”

Ian represents states, state-owned entities and trading companies in complex arbitration proceedings, regularly appearing in hearings in London and internationally. 

His experience includes disputes linked to energy, commodities and major infrastructure projects.

Ian added: “Keystone’s platform offers the flexibility and international reach that complex arbitration and energy disputes demand. 

“I’m looking forward to working with colleagues across the firm to support my clients on their most significant matters.”

Their arrival follows the recent appointment of former Clyde & Co partner Ben Knowles and further reinforces Keystone’s 28-strong international arbitration team, which handles multi-million-pound disputes across leading global institutions.

James Knight, founder and chief executive of Keystone Law, added: “Ian and Milena are exceptional additions to our international arbitration team. 

“Their combined experience in high‑value, politically sensitive and multi‑jurisdictional matters strengthens our offering to clients across the globe. 

“Their arrival reinforces Keystone’s ability to attract top partners who want a more flexible and empowered way of practising at the highest level.”
