In 1664 under the royal charter creating the French East India Company, the Custom of Paris became the primary law in New France, supplemented with royal ordinances, e.g. the "Code Louis", consisting of the 1667 ordinance on civil procedure and 1670 ordinance on criminal procedure; the 1673 "Code Savary" on trade; and the 1685 "Code noir" on slavery. After the 1763 Spanish cession, however, this law was supplanted by the Spanish law contained in three primary texts: "Nueva Recopilación de Castilla", "Recopilación de las Indias", and the "Siete Partidas". Commercial law was governed by the Ordinances of Bilbao. Other laws included: "Leyes de Toro" (1505), "Fuero de Real", and the "Fuero Juzgo".
