Administrative and public law

Dentons

Dentons remains the first port of call for a host of high-profile private and public sector companies and public entities (including government ministries) seeking advice on public contracts relating to major infrastructure projects, with a particularly strong presence in the road and rail sectors. Alongside advising on the awarding and renewal of concession contracts, project financing and execution, the team is frequently sought out to handle sensitive litigation stemming from public contracts and regulated activities. Regulatory issues in the energy sector are also a key area of expertise. Practice head Marc Fornacciari, who is lauded for his ‘encyclopedic knowledge of public procurement law’, and the ‘inspiring’ Dorothée Griveaux cover the full spectrum of contentious and advisory work relating to public contracts. Inès Tantardini is also noted.
