Session 4 : The fragmentation of the spatial legal field

The 4th session took place on 29 April 2025 and focused on the Space Chair’s research axis 2, dedicated to the issue of Space as a common good.

Katia Coutant, a doctoral student in international public law at the University of Paris Nanterre, and a researcher associated with the Space Chair, is currently writing a thesis entitled ‘The natural resources of celestial bodies and international law’. She is president of the Association of Young Researchers in Space Law (AJCDS).

Her presentation focused on the issues surrounding the fragmentation of international law, in particular the relationship between international humanitarian law and the law of outer space in the event of international armed conflict.

Alban Guyomarc’h is a research associate at the Chaire Espace and a doctoral student in law at the Université Paris Panthéon-Assas, where he has been working on a thesis since 2021 on the subject of ‘space activities through the prism of private international law’.

In his presentation, Alban traced the development of space law from the early 1900s to the 2010s, recalling the major international treaties that laid the foundations of space law, and more recently, the growing role of national laws and the gradual shift in the places where these rules are decided.
