In the context of a background trace organized by the team of assistants of Professor Bernardino Bravo Lira, a group for which the author had just joined as a collaborator, a moment of curiosity led to the discovery of a historical piece that, unknowingly at that minute, would then help complement a historical-legal research conducted much earlier by Professor Alejandro Guzmán Brito. This was, no less and nothing less, than the minutes of the review given for the future minister Diego Portales in matters of Natural Law at the nascent National Institute, in 1814. This document puts this piece into context and, in turn, puts it in relationship with the predeveloped works for proper complement.
