David Sanz has been a partner in the Administrative Law Department of Garrigues since 2010, having joined the firm in 1999. He has also been a lecturer in the Department of Administrative Law at the University of Barcelona since 1995. From the outset, his research work in the university sphere focused on the in-depth study of Administrative Law and its peculiarities, paying particular attention, as his publications attest, to the systems of prior administrative control over potentially polluting activities and the mechanisms of collaboration between the public authorities and companies. To this academic and research training must be added his experience in legal advice to companies and Public Administrations in different areas linked to Administrative Law and, specifically, in all matters relating to public procurement, regulated sectors, legal implications derived from environmental protection regulations and contentious-administrative proceedings, intervening both as a plaintiff and in defence of administrative action.

As regards aspects related to public procurement, he has participated in advising public authorities, contractors and financial institutions on a large number of the infrastructure projects promoted at national level in recent years (trams, metro, high-speed train, hospitals, motorways, desalination plants, water treatment plants, airports, waste treatment facilities, energy production facilities, etc.). He has also been involved in contractual modification, rebalancing and termination of public contracts.

He is also the head of the Barcelona office for matters related to environmental law, having provided advice in the field of the different environmental vectors (water, atmosphere, soil, etc.) and in matters related to ESG.

He also has extensive experience in advising on the regulatory aspects of renewable electricity production facilities, having been involved in numerous transactions involving the sale and acquisition of assets of this nature.

In addition to the above, David Sanz's experience in advising on any other matter related to administrative law, such as consumption, food safety, public property, expropriation procedures, telecommunications, sanctioning procedures or contentious-administrative appeals, should also be highlighted.

He is fluent in Spanish, Catalan and English.
