Presentation
In an environment where the boundary between the public and private sectors is becoming increasingly permeable, Ydès has chosen to develop complementary expertise in public business law. This responds to the growing need for both public and private stakeholders to master the legal issues linked to public action, public procurement, public property, and regulation.
We provide a pragmatic and strategic approach across all areas of economic public law, supporting you at every stage of your projects.
From tendering and negotiation through to contract execution and monitoring, the rules governing public contracts should be seen not as obstacles but as drivers of project success.
In matters of public property, we draw on our in-depth knowledge of legal mechanisms to support the enhancement of public assets or the optimisation of private partners’ economic activities.
We also support our clients in navigating public sector economic intervention and regulation, particularly in the fields of transport and energy.
Our approach is distinguished by a cross-disciplinary and proactive perspective: we advise on the structuring and implementation of projects, while also assisting with legal risk management and dispute resolution, drawing on our experience in both litigation and alternative dispute resolution.
Combining our expertise in business law with our understanding of public sector mechanisms, we are able to deliver tailored strategic advice that anticipates legal challenges whilst optimising the performance of your projects and activities.
