We are a law firm specialised in Administrative Litigation, which provides services and acts throughout Spain. We are based in Madrid, Badajoz and Cordoba. We also have representative offices in Barcelona and Seville.

Concept of the Administrative Litigation (Contencioso-Administrativo) order

The basis of the administrative litigation order is to control the legality of the administrative activity in order to guarantee the legitimate rights and interests of citizens in the face of overreaching by the Administration.

Our lawyers specialising in Administrative Litigation have extensive experience in this discipline, and are able to deal with all types of proceedings in this area with full solvency.

Usefulness of the Administrative Litigation (Contencioso-Administrativo) appeal

Therefore, in order to carry out this control within the administrative jurisdiction, the law configures the so-called Administrative Litigation (Contencioso-Administrativo) appeal, which is a judicial instrument used to challenge provisions of a general nature and against express and presumed acts issued by the Public Administration at the state, autonomous community and municipal levels.

Parties to the Administrative Litigation (Contencioso-Administrativo) proceedings

The parties in the Administrative Litigation process may be:

  • The plaintiff (who formulates the claims).
  • The defendant administration (which raises defences).
  • The co-defendant (who also raises defences).

The claimant may be a natural or legal person, or a private or public person.

The defendant administration is the legal person that has carried out the action giving rise to the plaintiff’s claims (sometimes there may be more than one defendant public administration).

The co-defendant is a third person who is the holder of a subjective right or who has a legitimate interest, both of which may be affected by a judgment in favour of the plaintiff.

Acts subject to appeal before the Administrative Litigation (Contencioso-Administrativo) Courts

Our lawyers in Administrative Litigation Law frequently lodge this type of appeal against the following acts:

  • Against provisions of a general nature, as well as against acts adopted in implementation thereof.
  • Against express and presumed acts of the Public Administration that put an end to the administrative procedure, whether final or procedural, if the latter decide directly or indirectly on the merits of the case; determine the impossibility of continuing the procedure; or produce defencelessness or irreparable damage to legitimate rights or interests.
  • Against the inactivity of the Administration or against the de facto actions of the Administration.
