The Constitutions of Catalonia or Catalan constitutions were the laws of the Principality of Catalonia introduced and promulgated by the Count of Barcelona and passed by the Catalan Courts. Being the continuation of the legal framework of the Usages of Barcelona, the first constitutions passed by the Courts were promulgated in 1283. The last ones were promulgated by the Corts of 1705-1706. They had pre-eminence over the other legal rules, including royal decrees, and could only be revoked by the Catalan Courts themselves. The compilations of the constitutions and other rights of Catalonia followed the Roman tradition of the Codex.
