Il Tractatus de Praesumptionibus. Prime riflessioni sulla presunzione in Andrea Alciato

This article analyzes Andrea Alciato’s Tractatus de Praesumptionibus, a foundational text in the legal theory of presumptions. Through a historical and doctrinal lens, it explores the distinction between legal fiction and presumption, Alciato’s classification of praesumptio iuris et de iure and iuris tantum, and their procedural limits. The work is set in the broader historical and intellectual context of early 16th-century legal thought, highlighting its role in the development of presumption theory in European law.
