JOYN Public

  • High-profile court cases involving major infrastructure projects and industrial disasters
  • All aspects of public law, with particular expertise in environmental law 


JOYN public

JOYN Public covers all matters involving the relationship between people and public authorities. We resolve problems connected with public and administrative law, environmental and town planning law, constitutional law, the civil service, public procurement, as well as matters such as expropriation.

At the heart of public law

Logically enough, JOYN Public deals with the public. Its lawyers regularly contribute articles and research papers to academic publications. In this way they associate with other publicists, confront issues, and have a role in the development of the law.

The department is headed by Damien Jans, who holds a doctorate in law from UCL and teaches administrative law and environmental law there. This university activity requires and enables constant updating of knowledge, in fields that are constantly undergoing change.
