Francisco De Vitoria & Relectio De Indis (1539): The Foundation Of Universal Indigenous Title

1. The University of Salamanca and the Birth of Modern International Law

Delivered in 1539 at the University of Salamanca by Dominican theologian Francisco de Vitoria, the lecture titled De Indis Noviter Inventis (commonly cited as Relectio de Indis) constitutes the bedrock of modern international law and Indigenous rights jurisprudence.^[1] Confronting the brutal Spanish conquests of the Americas, Vitoria delivered an unprecedented forensic defense of Indigenous sovereignty. Vitoria examined the legal standing of First Nations, dismantling the imperial claims of the Holy Roman Emperor, the Pope, and European conquistadors, and articulating universal principles of human equality under natural law (jus gentium).^[2]

2. Universal Dominium: Indigenous Peoples as True Owners

Vitoria's supreme legal contribution was his definitive affirmation of Indigenous property rights and civil sovereignty.^[3] Vitoria established that Indigenous peoples were rational human beings who possessed true dominion (dominium verum) over their lands, goods, and civil communities, both in private property and public sovereignty.^[4] Vitoria explicitly refuted every standard imperial justification for dispossession: > 'The barbarians in question can not be barred from being true owners, alike in public and in private, by the sin of unbelief or by other mortal sins... before the arrival of the Spaniards these natives were the true owners in public and in private.'^[5] He ruled that European discovery gave no title to lands already inhabited, declaring that discovery grants property rights only over lands that belong to nobody (res nullius).^[6]

3. Vitoria's Indictment of British Colonial Practice in Australia

When evaluated against the principles of Vitoria's Relectio de Indis, the British colonisation of Western Australia in 1829 stands condemned as completely illegal under the classical law of nations.^[7] The British Crown had no lawful right to claim radical title over south-western Australia merely because the Bibbullmun people were non-Christians or lacked European-style agriculture.^[8] Bibbullmun clans possessed lawful allodial ownership of their clan estates (kalla-boodja), governed by ancient customary law.^[9] Under Vitoria's doctrine, the British invasion was an act of unjust aggression, obligating the Crown to full financial restitution and territorial return.^[10]

4. The Enduring Legacy of Vitoria in Modern Jurisprudence

Vitoria's Relectio de Indis was cited directly by Chief Justice John Marshall in the landmark US Supreme Court decision Worcester v Georgia (1832) and by Justice Brennan in Mabo v Queensland [No 2] (1992) to dismantle terra nullius.^[11] Vitoria proved nearly five centuries ago that Indigenous sovereignty is universal, inherent, and unassailable.^[12] For the Bibbullmun Sovereign Nation, Vitoria's scholarship provides unshakeable international legal authority confirming that traditional ownership survived the British invasion and remains legally vibrant today.^[13]
