Administrative law is an area of public law that regulates the organisation, services, and activity of the Public Administration, including its relationship with citizens and between different administrations.
Public Administration is understood to mean:
- The General State Administration.
- The Autonomous Communities
- The entities that make up Local Administration (Provinces, Municipalities, and Islands)
- Other public-law entities with their own legal personality, linked to or dependent on other Public Administrations.
The activity of the Public Administration is formalised through administrative acts, which are those issued in the exercise of its powers and functions, creating or recording legal effects.
Administrative acts may affect us directly or indirectly, through limitation or denial of rights, the imposition of penalties, negligence, or the causing of damages, etc. In this regard, the role of an Administrative Lawyer is to:
- Prepare applications, petitions, tenders;
- Assist and help complete any procedure;
- Provide legal advice
- Defend in administrative proceedings (appeals)
- Litigate in contentious-administrative (judicial) proceedings.
The main areas in which our team of IN DIEM Administrative Lawyers provides services are:
- Fines and Penalties. Sanctioning Procedure.
- Review of Cadastral Values
- Public Procurement and Tenders
- Civil Service
- Compensation. Non-contractual liability of the Public Administration.
- Grants and Aid
- Compulsory Expropriation
- Regulated Sectors
- Urban Planning
- Taxes
- Immigration and Nationality
Fines and Penalties. Sanctioning Procedure. Administrative.
Within its regulated powers, the Public Administration has the power to impose fines and penalties where citizens, natural or legal persons, breach the law and such consequences are duly provided for and regulated as an administrative offence.
The sanctioning power of Public Administrations is set out in two provisions of the Constitution itself:
“No one may be convicted or punished for actions or omissions that, at the time they were committed, did not constitute a crime, misdemeanour, or administrative offence, under the legislation in force at that time.” Art. 25.1 CE
“Likewise, everyone has the right to the ordinary judge predetermined by law, to defence and legal assistance, to be informed of the accusation brought against them, to a public trial without undue delay and with all guarantees, to use the relevant means of evidence for their defence, not to testify against themselves, not to confess guilt, and to the presumption of innocence.” Art. 24.2 CE
Administrative sanctioning law is based on the following principles:
- Principle of Legality
- Principle of Typification
- Principle of Non-Retroactivity
- Principle of Responsibility or Culpability
- Principle of Presumption of Innocence
- Principle of Proportionality
- Principle of Non bis in idem
Once you have been notified of, or become aware of, the existence of a sanctioning administrative procedure
, it is advisable to use the existing legal framework to submit the relevant allegations and the evidence deemed appropriate for the purposes of defence, if you wish to mount a defence, in order to avoid the penalty or reduce it to what is truly proportionate.
Due to the extensive powers of the Public Administration, the following are common procedures:
- Urban Planning
- Noise
- Traffic
- Prohibited Substances
- Social Security
- Tax-related
- Etc.
IN DIEM Abogados makes available to you a specialist team of Administrative Lawyers to assist you with whatever you need and to exercise your right to defend yourself.
Review of Cadastral Values.
The Cadastral Value is, as a general rule, the tax base for real estate, and therefore affects:
- Real Estate Tax (IBI, known as “contribución”);
- Personal Income Tax (IRPF) in relation to income from real estate not used for a business or professional activity and that is not the main residence;
- Non-Resident Income Tax
- Tax on the Increase in Value of Urban Land (Plusvalía)
- And for the verification of the value to be set for Transfer Tax and Inheritance and Gift Tax.
IN DIEM Abogados defends owners in the event of changes to data or changes to cadastral values, submitting the relevant allegations and/or appeal before the Tax Agency or the Economic-Administrative Court; for these purposes, all means are used to correct the errors that commonly occur in these changes and revaluations, preventing the increase in the tax burden that they usually entail.

Liability of the Public Administration
The non-contractual liability of public administrations is the State’s obligation to repair or compensate for damage caused by the operation of any of the Public Administrations that make it up.
This obligation to repair and compensate is provided for in the Spanish Constitution:
“Individuals, under the terms established by law, shall have the right to be compensated for any harm they suffer to any of their property and rights, except in cases of force majeure, provided that the harm is a consequence of the operation of public services.” Art. 106.2 Spanish Constitution
“Damage caused by judicial error, as well as that resulting from the abnormal functioning of the Administration of Justice, shall give rise to compensation payable by the State, in accordance with the law.” Art. 121 Spanish Constitution
The situations that may give rise to this non-contractual liability of the Administration are:
- Due to normal or abnormal operation of public services
- Due to legislative acts
- Due to judicial actions arising from judicial error.
It should be borne in mind that the time limit for filing a claim is ONE (1) year from the occurrence of the event that may give rise to compensation. In the case of physical or psychological harm, the one-year period will begin to run from recovery or from the determination of the extent of the after-effects.
And the requirements for non-contractual liability of the Administration to apply are:
- Existence of compensable DAMAGE or INJURY; that is, actual damage, economically assessable, and individualised to a person or group of persons.
- Damage ATTRIBUTABLE to a Public Administration.
- A CAUSAL LINK between the damage and the operation of the Public Administration.
- The damage must be UNLAWFUL; that is, the citizen must not have a legal duty to bear it.
Common claims include the following:
- Falls on public roads due to poor maintenance.
- Claims for compensation for medical errors
- Accidents due to lack of road maintenance or lack of signage.
- Falls in public buildings due to lack of proper maintenance
- Non-contractual liability in urban planning matters
- Compensation in public procurement matters for breaches of contract
- Compensation for errors in the administration of justice, such as: wrongful deprivation of liberty or undue delays.
