The restoration of Ferdinand VII and the formal comeback of Basque institutions (May–August 1814) saw an overturn of the liberal stipulations approved on the 1812 Constitution of Cádiz, but also a serial breach of basic fueros provisions (contrafueros) that came to shake the foundations of the Basque legal framework, such as fiscal sovereignty and specificity of military draft.
The return to Ferdinand VII and the formal revival of Basque institutions in 1814 resulted in the repeal of the liberal provisions established by the 1812 Constitution of Cádiz, but also a pattern of violations of fundamental fueros regulations (contrafueros) that ultimately threatened the stability of the Basque legal system, including its fiscal independence and military draft specificity.
