It is not enough to know the law to be a good lawyer. An interdisciplinary approach with a strong humanistic, economic and business component ensures that lawyers – and especially arbitrators – make decisions with greater sensitivity and based on an in – depth analysis.
Only then will we be more lucid, more attentive and more aware of the world around us. In the world of arbitration, this means that we must make people’s lives easier: we must untie knots.
I am an arbitrator and a legal expert. I am a member of the Council of the ICC Institute of World Business Law of the International Chamber of Commerce of Paris (CCI), of the International Court of Arbitration of the American Chamber of Commerce of Peru (AMCHAM Perú) and of the Board of Directors of the Peruvian Chapter of the Spanish and Ibero-American Arbitration Club (CEIA).

One of the most beautiful, significant and relevant aspects of my professional life is my academic life.
Until 2022, I was linked to Universidad del Pacífico in Peru for twelve years, where I was a senior lecturer and Dean of the School of Law, after being head of the Academic Department of Law and Vice-dean. I am now continuing my teaching activity in Spain, at Universidad Carlos III de Madrid.
Cecilia O’Neill took part in the Lima Arbitration Open 2025, where she moderated a panel inspired by Mario Vargas Llosa’s Conversation in the Cathedral, exploring the dilemmas of arbitral impartiality.
