Administrative law

Administrative action frequently bears on economic or property interests: ownership, real estate, business activities, licences, valuations, expropriations, taxes or compensation. That reality explains the close connection between our public and administrative law practice and the firm's specialisation in property and contract law.

Public law calls for a command of the rule to be combined with a command of the procedure. An authorisation, a licence, a penalty, an expropriation or a planning measure may produce economic and property consequences of particular significance. We therefore approach each matter from its earliest stage, seeking to anticipate the risks and to build the client's legal position before the dispute reaches the courts. Where the controversy cannot be resolved through the administrative route, we take on its defence before the administrative courts.

The firm's litigation experience and our command of property law allow us to bring together within a single strategy the legal regime governing administrative action, its economic consequences and the defence of the affected interests before the courts.

Administrative law and defence before the administrative courts

We advise and defend our clients in administrative proceedings of very different kinds, including penalty, disciplinary, tax and cadastral proceedings, as well as in matters of authorisations and licences, grants and grant recovery, civil-service employment, “vía de hecho” (unlawful de facto administrative action) and administrative concessions.

Wherever possible, our involvement begins before the public authority adopts a final decision. We examine the background, the applicable rules and the consequences of each alternative; we prepare submissions, respond to formal requests and lodge the appropriate administrative appeals. Once the administrative route is exhausted, we take on the conduct of the administrative-court proceedings at their various instances.

Planning law and expropriation

Planning law is one of the most specialised areas of our public law practice. We advise on planning instruments and planning implementation, reparcelling and site infrastructure schemes, “juntas de compensación” (landowners' development associations) and other collaborating planning entities, planning agreements and the processing of licences and authorisations. We also act in proceedings for the protection of planning legality and planning enforcement, inspections, restoration orders, penalties and other administrative action capable of affecting the use, the transformation or the development potential of real estate.

In matters of compulsory expropriation, we accompany the client throughout the procedure. We analyse the assets and rights affected, review their economic valuation, prepare the “hojas de aprecio” (the formal valuation statements) and act before the relevant valuation bodies. Our involvement also covers reversion proceedings and challenges to expropriation decisions, both in administrative proceedings and before the administrative courts.

Local taxation and State liability of the public authorities

Within our public law practice, we provide specific advice on local taxation and cadastral procedures. This is a field distinct from general tax advice, closely bound up with the action of local authorities and with the ownership and valuation of real estate. We act on questions concerning local taxes, cadastral values and schedules of cadastral values, returns and notifications to the “Catastro” (the property cadastre), the correction of discrepancies, administrative appeals and claims before the “tribunales económico-administrativos”, Spain's specialised tax tribunals.

We also have experience in State liability claims for damage arising from the functioning of the public authorities. We analyse the existence and the valuation of the damage, its connection with the administrative action and the remaining requirements for the claim. We then bring the claim through the administrative route and, where necessary, take on its defence before the administrative courts.

Pharmacies

We have specific experience in advising the owners of pharmacies and the professionals connected with them, an activity subject to intense administrative regulation in which regulatory decisions bear directly on the value and the continuity of the business.

We advise on studies and procedures relating to the establishment of new pharmacies, relocations and alterations to premises, the opening of “botiquines” (subsidiary medicine dispensaries) and other administrative action connected with the authorisation and the operation of the pharmacy.

Our practice also covers the sale and purchase and the gift of pharmacies. In these transactions we combine the administrative element with our experience in property and contract law and in contract practice, so as to offer an integrated view of the administrative authorisation and of the legal and economic transaction that accompanies it.

Work commissioned without a valid contract: what the contractor can recover from the public authority

Irregular procurement by public authorities, in particular through oral commissions or contracts that are void for breach of the procurement rules, raises a classic conflict between the prohibition of contracting outside the law and the need to prevent the unjust enrichment of a public authority that has received and taken the benefit of the works or services. The judgment of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 15 June 2026, Fourth Section, cassation appeal 9117/2024, sets precise limits on the compensation available in such cases: the contractor may recover the actual cost of the works or services, including any value added tax —the Spanish “Impuesto sobre el Valor Añadido”, or IVA— which it has been unable to recover, but not the overheads (“gastos generales”) or the profit mark-up (“beneficio industrial”) proper to a validly awarded contract. Moreover, the late-payment interest regime of Law 3/2004 on combating late payment in commercial transactions does not apply automatically; what applies is the statutory interest laid down in the “Ley General Presupuestaria”, Spain's General Budget Act. The question is of particular relevance for local-authority contractors and public bodies which, in practice, continue to receive work without proper contractual cover.

Administrative electronic notifications: how the ten days for them to be deemed refused are counted

The spread of electronic notifications has made the calculation of time limits a critical element in the relationship between citizens, businesses and the “Administraciones Públicas”, Spain's public authorities. Article 43.2 of the “Ley 39/2015, de 1 de octubre, del Procedimiento Administrativo Común de las Administraciones Públicas” —Law 39/2015 of 1 October, the Common Administrative Procedure Act— provides that, where electronic notification is compulsory or has been expressly chosen by the party concerned, it is deemed refused once ten calendar days have elapsed from the moment it was made available without its content being accessed. The judgment of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 12 June 2026, in line with the Chamber's official report for the 2025–2026 biennium, clarifies for the first time that those ten calendar days run from the day after the notification is made available to the party concerned on the “sede electrónica”, the authority's electronic portal, or at the “dirección electrónica habilitada única”, the single authorised electronic address. Once the period has elapsed without access, the notification is deemed refused and the time limits for appeal begin to run. The decision has direct consequences for businesses, professionals and citizens required to deal with the authorities by electronic means and underlines the importance of checking electronic mailboxes regularly.

A prior notification allows the activity to begin, but it is not an administrative authorisation

The widespread use of the prior notification and of the “declaración responsable” —the declaration of compliance— as instruments replacing licences has transformed the way in which citizens and businesses deal with public authorities. That transformation has, however, also given rise to confusion as to the legal nature of these instruments and as to their review by the courts. The judgment of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 20 April 2026, Fifth Section, cassation appeal 2290/2023, makes it clear that a prior notification is not an administrative act open to challenge as though it were a licence. It is a declaration by the private party to which the law attributes authorising effect, enabling the activity to be started or the right to be exercised from the day of its filing, without prejudice to the public authority's subsequent powers of verification, inspection and response. If false statements, omissions or breaches come to light, it is the subsequent administrative act –of ineffectiveness, suspension, closure or penalty– that may be challenged. The doctrine has significant consequences for business openings, economic activities, property owners, local councils and affected third parties.

New urban developments and water availability: when a planning instrument can be annulled

Urban expansion is no longer measured solely in square metres of classified land, but also in cubic metres of legally available water. The judgment of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 15 April 2026, Fifth Section, cassation appeal 9014/2023, clearly establishes that the creation of new development areas requires the sufficiency and the legal availability of water resources to be verified, even where the municipality is losing population. The binding report of the river basin authority, the Spanish “organismo de cuenca”, cannot be omitted or deprived of content where the development will generate new demands for water, and failure to comply with it may lead to the annulment of the plan. The judgment also accepts that the annulment may be confined to particular sectors where the defect can be isolated without affecting the coherence of the rest of the plan. The doctrine is of direct interest to developers, landowners, local councils and practitioners involved in preparing or challenging planning instruments.

Public authorities that decide by algorithm: what transparency the BOSCO case requires

The progressive automation of administrative action has brought to the fore the question of how decisions taken by means of algorithms are to be explained and reviewed. Judgment 1119/2025 of 11 September of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, known as the BOSCO case and highlighted in the Third Chamber's official case-law report for 2025–2026, marks a landmark in this field by recognising that, where public authorities use automated systems to grant rights or social benefits, the right of access to public information may require, in certain circumstances, that even the source code of the program be disclosed. The decision rests on article 105 b) of the Spanish Constitution, on Law 19/2013 on transparency, access to public information and good governance, on the rules governing automated administrative action in Law 40/2015 and on the European data protection framework of Regulation (EU) 2016/679 —the GDPR—. Algorithmic transparency ceases to be a technical question and becomes a structural requirement of the digital rule of law.
