Spain's 1978 Constitution granted areas of competence competencias to each of the autonomous regions it created. It also established that these could be modified by agreements, called estatutos de autonomía or just estatutos, between central government and each of the autonomous regions. The latter do not affect the competencias of central government which controls the army, etc. For example, Navarre, the Basque Country and Catalonia have their own police forces and health services, and collect taxes on behalf of central government. Navarre has its own civil law system, fueros, and can levy taxes which are different to those in the rest of Spain. In 2006, Andalusia, Valencia and Catalonia renegotiated their estatutos. The Catalan Estatut was particularly contentious.
