1973 Professor Inaugural Lecture: 'On the Interface between Public and Private International Law'

The inaugural lecture of Professor Campbell McLachlan as Professor of Law 1973.

Abstract: Our understanding of the operation of law beyond the nation State has been deeply shaped by two great disciplines: public and private international law. Yet surprisingly little systematic attention has been devoted to the relationship between the two. In his inaugural lecture as Professor of International Dispute Resolution in the University of Cambridge, McLachlan argues that the neglect of this interface is highly consequential for our understanding of law’s capacity to control the State and the corporation, which are, respectively, the principal holders of public/political and private/economic power in the world.

Campbell McLachlan is elected as Professor of Law (1973) in the University of Cambridge and a Fellow of Trinity Hall.

His principal works include: Foreign Relations Law (CUP 2014), International Investment Arbitration: Substantive Principles (2nd ed, OUP 2017) and The Principle of Systemic Integration in International Law (2024). He is a Specialist Editor of Dicey, Morris & Collins on the Conflict of Laws. He gave the General Course at The Hague Academy of International Law in January 2024.
