Young Public International Law Group
Connecting PIL practitioners
Welcome
The Young Public International Law Group (“YPILG”) is a network of young public international law practitioners from law firms, the bar, international organisations, governments and academic institutions around the world. The purpose of YPILG is to connect early to mid-career PIL practitioners to one another, to facilitate exchanges of ideas and knowledge-sharing in the PIL field, and to promote the next generation of PIL professionals.
The YPILG hosts a number of events throughout the year, lectures by leading academics and practitioners of public international law topics, practical training sessions in PIL practice and other informal networking events.
