Legal Force and Effect of Spain’s Constitution

Posted on Apr 17, 2025 in Law & Jurisprudence

Legal Value of the Spanish Constitution

  1. The Spanish Constitution (EC) is a fundamental legal standard; the constituent power established its legal status. The Constitutional Court (TC), in its first ruling, affirmed that the EC is the supreme legal rule of the legal system (OJ), and its precepts can be invoked in court.
  2. The EC binds both citizens and public authorities. It comprises various rules and precepts, although not all have the same level of effectiveness. Its supremacy is guaranteed judicially, and the EC itself creates an organ, the Constitutional Court (TC), to ensure this superiority through specific mechanisms and procedures for constitutional guarantees.
  3. All legal standards must be compatible with the EC. The Constitution establishes the framework for other rules and sources within the legal system, acting as the ultimate standard of legitimacy and regulating the validity of other norms (OJ).
  4. Effectiveness: While the EC binds everyone, its precepts are diverse. Rules regulating fundamental rights possess full and complete effectiveness. They may be invoked directly before the courts in case of breach.
  5. The EC also sets out guiding principles for social and economic policy. These are mandates to the legislature, providing guidance, and should not be confused with individual rights directly enforceable by citizens.
  6. There are also rules or principles establishing governmental mandates, which are obligations for the government to consider specific aspects.
  7. The Constitution itself contains different types of rules.
  8. The EC possesses legal value throughout its text, but different provisions within it have varying levels of efficiency and effectiveness. Some rules require legislative development by the legislature to become fully effective and part of the legal system (OJ). Until this development occurs, these rules may not be directly applicable.
    • Direct Effect Example: Article 17 EC: “1. Everyone has the right to liberty and security. No one shall be deprived of his liberty except in accordance with the provisions of this Article and in the cases and manner provided for by law. 2. Preventive detention may last no longer than the time strictly necessary for the completion of the investigation aimed at establishing the facts; in any case, the person detained must be released or brought before the judicial authority within a maximum period of seventy-two hours. 3. Any person arrested must be informed immediately, and in a way understandable to him, of his rights and of the grounds for his arrest, and may not be compelled to make a statement. The assistance of counsel is guaranteed to the person arrested during police and judicial proceedings, under the terms established by law.”
    • Delayed/Indirect Effect Example (requiring development): Article 47 EC: “All Spaniards have the right to enjoy decent and adequate housing. The public authorities shall promote the necessary conditions and establish appropriate standards to make this right effective […].”
  9. The EC itself differentiates between provisions with direct effectiveness (invocable before courts or public authorities) and those whose effectiveness is dependent on further legislative action.
  10. Legislative development is an essential element for the rights outlined in Chapter III; their effectiveness is not the same as that of other constitutional provisions.
