The King of Aragon was bound to summon the Cortes at least once every five years, and, following the union with
Catalonia, annually. The main business of the Cortes was judicial: solving disputes between individuals or towns or dealing with complaints or grievances concerning the King's officers or Estates. For the more important laws, unanimity was required between each of the Cortes' four Estates (
nemine descriptante). Each member could veto any law, in which case the decision would be recorded as
unamiter excepto N.N. which allowed for further debates and discussions, although these often ended in stalemates with no agreement being reached. In such cases, the decision was referred to a permanent committee which consisted of two representatives of each Estate who would judge whether the existing majority will was sound or not. These Cortes were the model for the parliaments of
Sardinia and
Sicily. The Cortes survived until 1707 when
Philip V issued the
Nueva Planta decrees, centralising political power and abolishing the former regional assemblies of the
Crown of Aragon. ==Current Cortes==
