Spanish Legal System: Validity, Publication, and Application of Norms

Legal Gaps and the Application of State Law

If an Autonomous Community (AC) does not legislate, two options arise:

• Do not apply any law.
• Apply the general law (State law).

If the Autonomous Community (CCAA) legislation is absent, a legal vacuum occurs, and the law of the State applies additionally. State law enters due to this failure (of CCAA legislation) and prevails over the CCAA norms in this context.

Defining the Legal System: Validity and Enforceability

The legal system is composed of rules that must be valid and enforceable.

Criteria for Rule Validity (Hierarchy, Jurisdiction, Procedure)

Criteria of hierarchy, jurisdiction, and procedure determine if the rules are valid. Validity requires that rules be created by competent bodies, following the correct procedure, and respecting the necessary hierarchy.

Rules may be valid or invalid, or valid but not yet applicable. The validity of rules in our system is determined or controlled by a Constitutional Tribunal (CT), which assesses whether the system's rules are valid. This control covers the validity of each standard throughout its evolutionary cycle.

Publication and Entry into Force (Vacatio Legis)

The commencement of the term begins with the publication. Rules become effective upon publication, noted unmistakably through official advertising.

Official Publication Channels

Standards are published in the Boletín Oficial del Estado (BOE) and Autonomous Bulletins (e.g., DOGC for Catalonia). Each standard has territorial scope (State and Regional), and each Autonomous Community (AC) maintains its own official journal where it publishes its own rules.

The General Rule of Vacatio Legis (20 Days)

After publication, a period known as vacatio legis is necessary before the rule takes practical effect. Although published, the rule does not immediately produce effects. The legislator introduces this period so that legal practitioners can become aware of the standard before it is applied. The general period is 20 days after publication in the official bulletin.

Exceptions to the 20-Day Rule

This 20-day period is a general criterion, but some rules take effect immediately, while others have a significantly longer vacatio legis:

• Rules producing immediate effects: e.g., Decree Law.
• Rules with a period exceeding 20 days: Complex rules, such as the Penal Code (CP), cannot enter into force after only 20 days of publication. Such complex rules require a longer period, for example, six months.

Scope of Application: Territoriality and Personal Status

Generally, rules are applicable territorially; they are effective and produce effects within a given territory, obligating those who reside or are present there.

Exceptions to Territoriality

Some rules are effective personally, depending not on the territory but on the condition and personal status of the subject.

Temporality and Non-Retroactivity (Art. 9.3 CE)

Regarding the validity and temporality of rules: generally, rules cannot have retroactive effects. The core principle is enshrined in Art. 9.3 of the Spanish Constitution (CE):

"The Constitution guarantees the principle of legality, the hierarchy [of norms], the publicity of norms, the non-retroactivity of punitive provisions unfavorable or restrictive of individual rights, the legal certainty, the accountability of public authorities, and the prohibition of arbitrariness."
