ESIL Sponsored event

General Principles as applied by International Courts and Tribunals and the coherence of International Law

When: 21-22 June 2017

Where: Centre Universitaire de Norvège à Paris, Fondation Maison des Sciences de l’Homme 54, Boulevard Raspail, 75006 Paris.


General principles – with peremptory norms (jus cogens) at the core – constitute the general foundations of international law. In times of turmoil and when the treaty-making process and custom formation are less effective, general principles may play a more important role.

The seminar will bring together experts from academia and practice to discuss the contribution of general principles to the coherence of international law (i) through the jurisprudence of international courts at a general level; (ii) in constitutionalisation and hierarchy, including jus cogens; (iii) in developing interim, compensatory and other remedies and the principles of effectiveness; (iv) for the principles of proportionality, subsidiarity and the doctrine of the margin of appreciation; and (v) for res judicata, lis pendens and other jurisdictional rules.

The purpose of this seminar is to provide a smaller forum for an informal exchange on the core issues, including how to take the project forward, including the prospect of forming a working group under the International Law Association on general principles of law in the international legal order.

The seminar will be held in English and French.
