Public law

We support a wide variety of actors: public and semi-public entities (national and local), private players (industrialists, financial institutions, investment funds, etc.) in all aspects of public law, providing them with in-depth expertise adapted to their specific needs.

 

Areas of intervention in public law

General public law

We advise our clients on matters relating to general administrative law, including relations between citizens and the administration, fundamental principles of public law and administrative acts.

Institutional public law

We assist our clients in understanding and implementing the institutional rules that govern public entities, whether at the national level (creation, transformation or disappearance of legal persons under public law) or at local level (in particular with regard to local authorities and public establishments for inter-municipal cooperation (EPCI)) or which provide a framework for mergers between legal persons governed by public and private law (creation of structures para-public sectors, the establishment of partnerships or all forms of institutional cooperation between the public and private sectors).

Public procurement law

We offer our expertise in public contracts and in particular complex public contracts (global public contracts, concessions, partnership contracts, etc.), assisting our clients throughout the procedures for the award and execution of public contracts, both in advisory and litigation matters. We have developed particular expertise in the financing of public infrastructure projects.

Public ownership and public works

We intervene on issues relating to the management of the public domain, the occupation of the public domain and public works, ensuring compliance with the rules specific to these matters, in particular for project management assistance projects and the development of private activities on the public domain.

Administrative litigation

We represent our clients before the administrative courts, whether in first instance or on appeal, in all matters of public law.

We also intervene in the amicable settlement of disputes (mediation, settlement, etc.).

Environment

We advise on environmental issues, including classified facilities, polluted sites and the development of renewable energies, ensuring compliance with environmental regulations and supporting related financing projects.

Electronic communications and network law

We support our clients in the field of electronic communications, advising them on regulatory and contractual aspects related to electronic communications networks and services.

Public health law

We intervene on issues relating to public health, advising the players in the sector on regulatory and legal aspects.

Right of defence

We offer our expertise in defence law, both on regulatory and contractual aspects, including in the military, aerospace and cybersecurity sectors.

Town planning

We intervene in urban planning matters, advising on planning permission procedures, local urban plans and development projects, both in advisory and litigation matters.

Examples of support in public law

We have provided legal advice to a government on the renewal of an airport concession. As such, we drafted the specifications, published the tender notice and negotiated the award of the contract with the candidates. We have also drafted the deliberations allowing the authorization of this allocation.

We represented the interests of a pharmaceutical company in a dispute with the French State, which refused to grant public reimbursement of an orphan drug prescribed for very rare pathologies. The main issue in this dispute was to obtain a reimbursement rate that would allow the marketing of this drug. Without this, more than 10,000 patients in France would not have access to this treatment, which is vital for their pathology.

We advised a public institution on the creation of a holding company with several private sector legal entities, in order to invest in solar projects in a specific region.

The project involved our assistance in structuring the transaction, in particular due to issues related to public law, as well as in negotiating the legal documentation with all the actors involved.

We supported a government in an engineering mission to design, finance and build the first transatlantic submarine cable directly linking Latin America to Europe. This project, in addition to its economic interest, is of major strategic importance, as it will directly connect a space base to Europe.

We assisted a pharmaceutical company in two ongoing litigation cases against a major competitor, concerning advertisements deemed contrary to the French Public Health Code for HIV drugs. The company is seeking compensation for the damage related to this unfair competition.

We advise financial institutions in connection with the implementation of the financing of works on several waste-to-energy units operated under public service concessions.
