Public and Regulatory Law

Start of main content

In the field of public law Andersen has wide experience and provides specialist legal advice, both to private individuals and companies and the public authorities and the public sector.

Our advice includes writing reports, taking part in negotiations, drafting contracts, as well as providing legal defence to our clients in all administrative proceedings as well as in contentious-administrative files in the different scopes of our practice (urban planning, public contracts, compulsory expropriations, public service, administrative organization and local governing rules, assets held by public administrations, subsidies, infrastructures, regulated sectors, etc.).

Specifically, we have extensive experience delivering recurrent advice to public authorities and other public-sector entities in matters related to their organization and functioning, drafting laws and regulations, managing their proprietary assets, and in matters relating to their personnel.

In public sector contracting matters, we assist public administrations and public entities by drawing up contract instructions, including terms and conditions sheets, advising in public contracts bidding and execution. In the private sectors, we advise bidders in their submission of bids, the execution, amendment and termination of contracts, and when challenging bidding decisions, also assisting in court where necessary.

In regulated sectors, we have extensive experience in many Administrative Law areas, including water, coasts, energy, mining, telecoms, tourism and transportation.

We advise also in cases involving compulsory expropriation, liability, public aids and, generally, in all areas of Regulatory Law.
