Associate Professor, SJD (University of Toronto); LLM (University of Toronto)

  • The University of Western Australia (M253), 35 Stirling Highway,

    6009 Perth


Personal profile


Dr. Sagi Peari researches and teaches within private law, commercial law, international law and their intersections. He is an author of two research monographs published by Oxford University Press: The Foundation of Choice-of-Law: Choice & Equality (New York: Oxford University Press, 2018) and International Negotiable Instruments (with Professor Benjamin Geva) (Oxford: Oxford University Press, 2021). Sagi is the only Australian academic who has authored two research monographs in law with Oxford University Press. His papers have been accepted for publication in leading UK, US, Canadian and Australian journals, including Oxford Journal of Legal Studies, Cambridge Law Journal, American Journal of Comparative Law, Delaware Journal of Corporate Law and the University of Toronto Law Journal. Presently, with Professor Warren Swain of the University of Auckland, Sagi leads a global interdisciplinary initiative to tackle the current incoherency of private law. 

In essence, Sagi’s scholarship lays out a global theory of just public institutions and the legal effects of cross-border interactions, which extends its conceptual argument to concrete legal categories: contracts, torts, restitution, negotiable instruments, corporations and taxation. His work shows how the traditional legal doctrines, principles and concepts can be accommodated and qualified within the advancing reality of the digital age and online communications. 

Sagi holds an SJD degree from the University of Toronto where he was the recipient of the prestigious Joseph-Armand Bombardier and Connaught Doctoral Fellowships. He was also a recipient of the Hauser Global Fellowship at New York University Law School, and of the Connection Grant from the Social Sciences and Humanities Research Council of Canada. One of Sagi’s papers received the best paper prize award from the American Society of International Law. Another paper received the best paper prize award from the Corporate Law Teachers Association of Australia, New Zealand and the Asia Pacific region.

Sagi is also a passionate teacher whose classes are filled with joy, positive spirit, friendly attitude and comprehensive treatment of the legal doctrine. He is a recipient of the 2019 & 2020 UWA Student Guild Choice Awards and the 2020 & 2022 Faculty's and Law School's Excellence in Teaching  Awards. In April 2023 Sagi received the 2023 UWA's Excellence in Teaching Award.
