Melis Acuner is a Partner in Quinn Emanuel’s London office, where she specialises in international arbitration and litigation with a focus on complex cross-border disputes. Melis has successfully represented clients in numerous cases conducted under the auspices of all the major arbitral institutions and before ad-hoc tribunals - including corporations and national governments across a broad spectrum of industry sectors, such as energy, telecommunications, media, construction, banking and finance, insurance and pharmaceuticals. 

Recent arbitrations have included shareholder disputes, complex oil and gas contracts, media broadcasting rights, petroleum industry joint ventures, telecoms investment disputes, gas sales agreements, and gas pricing and repricing formulae. Her representative cases often involve a mix of national laws and investment treaty systems, making them legally and factually complex, especially in challenging jurisdictions.

Melis has received recognition and accolades from multiple organisations for her exceptional work in arbitration, including being named a Future Leader in arbitration by Who’s Who Legal since 2016, quoting peers and clients who state she “"is a great lawyer and very well regarded for international arbitration", "She is hardworking, diligent and creative" and "She always puts the client first and is known to develop solid and constructive relationships with her clients". Chambers Global has ranked Melis for international arbitration since 2022, recognising Melis as a prominent and notable practitioner, noting that “Melis is excellent - she's able to handle the most demanding clients". Furthermore, her practice was also recognised by The Legal 500 for its expertise in international arbitration and she has been featured in their “International Arbitration Powerlist UK” since 2019.

As well as being one of Turkey's representatives to the ICC Commission, Melis is a regular conference speaker on topics relevant to international arbitration and in relation to legal developments in the energy sector, in particular.

Melis practices bilingually in English and French, speaks fluent Turkish, and is proficient in Spanish. She is dually qualified to practise in England and Wales, and France, and is a graduate of the Universities of Pantheon-Assas Paris II and the London School of Economics.
