This event is co-organised annually with the International Institute of Space Law (IISL) and takes place at the opening of the annual session of the Legal Subcommittee of the United Nations Committee on the Peaceful Use of Outer Space (UNCOPUOS) in Vienna, Austria. The IISL and ECSL are both observers at the Legal Subcommittee.

This Symposium brings together academic experts and leading practitioners in the field of space law, policy and regulation to discuss pressing issues and to propose solutions to the international community.


Message to our community:
