ley de aguas (12. 371)

Arising from necessity over a thousand years ago and held every Thursday up to the present day, the Tribunal of the Waters of Valencia among farmers and public works (nine by tradition called the Comunitat de Regnant) seeking access to the irrigation system of the extensive network of canals diverting water from the Túria sourced from the Iberian Montes Universales watershed to the plain for agricultural and domestic use, it is the oldest customary court in the world also counting as the most venerable democratic institution in Europe. Proceedings are held orally, called by the bailiff to hear out disputes and the council to pass judgment, and no written records are kept, and begun during the age of the Caliphate to manage water resources, the tribunal originally held in the city’s central mosque, the venue replaced by a cathedral during the Reconquista are held out-of-doors and open to the public to ensure all plaintiffs have access to a fair hearing with decisions being final and not up for appeal outside the unique justice system.
