A Constitution That Did Not Draw the Map
The 1978 Constitution did not draw Spain's territorial map. Instead, it provided a route to self-government.
Two access paths were available:
- The fast route (Article 151): Granted immediate maximum Autonomy. Used by historical nationalities (Catalonia, the Basque Country, Galicia) and Andalusia.
- The slow route (Article 143): Started with fewer competences, expandable after five years.
This process produced 17 autonomous communities (or 17 regions) and two autonomous cities, Ceuta and Melilla.
Competence Allocation
Two articles govern the distribution of powers:
- Article 148: Lists matters communities may assume.
- Article 149: Lists exclusive state powers and contains a residual clause.
A Statute of Autonomy acts as each community's basic institutional norm. Because each Statute is also a state law, the Constitutional Court frequently adjudicates territorial disputes.
Asymmetric Autonomy
The Spanish model is explicitly asymmetric rather than uniform:
- The Basque Country and Navarre retain historical foral tax systems.
- Specific Statutes recognise distinct languages and island realities.
Federal or Not?
The Constitution avoids the word "federal". Scholars remain divided:
- For: Protected legislative powers, regional Statutes, and a Constitutional Court resolving conflicts.
- Against: A weak Senate, expansive central framework powers, and no regional role in constitutional reform.
In practice, Spain is federal in its practical operation and not in its constitutional self-description.
Common pitfall: Viewing asymmetry as a design flaw. It was an essential compromise in 1978 to accommodate diverse regional demands.
