Introduction

I have spent my entire career at UGGC Law Firm! I joined the firm as a trainee in 2010 and quickly integrated the Public Law department of the firm, of which I became a partner in 2020.

I am passionate about this expertise that allows me to be at the crossroads of public and private interests. I enjoy advising both private operators and public bodies in the context of public projects, and defending both parties in the context of litigation that may arise between them.

UGGC & I

At UGGC, I find all the necessary assets to offer our clients a legal response with high added value: high standards, a constant search for excellence, multidisciplinary, an international dimension and an entrepreneurial mind-set.

In addition, there are two essential ingredients: a real pleasure in working together and a great team cohesion.

My practice:

There are three main aspects to my practice.

First of all, public contract law (public procurement, concessions, occupation of the public domain, etc.). I assist public entities and French and international private operators in the conclusion and performance of their contracts, both as counsel and in litigation, with particular expertise in infrastructure concessions and PPPs (public-private partnerships). I am often involved in dealing with difficulties in the performance of public contracts, both in litigation and in the context of alternative dispute resolution.

Secondly, the regulation of economic activities. I assist clients in highly regulated sectors (transport, gaming, energy, data, health, etc.) or in matters where public authorities are involved (State aid, public company law, foreign investment control, etc.). In particular, I represent numerous private operators before domestic and European courts and authorities, in the context of contentious challenges to decisions or rules, or their consequences in terms of compensation. I also assist these operators in the context of their public affairs strategy.

Thirdly, compliance and  criminal law. I advise numerous clients on public criminal law and ethics, both in the context of litigation before the criminal courts, in conjunction with the firm’s criminal lawyers, and in the implementation of prudential measures – in particular the obligations arising from the Sapin II law.
