 To consider the Bourbons as non-dynasts in France, the Orléanists based their claims on an interpretation of the "Arrêt Lemaistre", taken by the parliament sitting at Paris on June 28, 1593.Orléanists claim, that a ""vice de pérégrinité"" (defect of foreignness) affects princes who become foreigners, with "no intention of returning," that is to say, having ceased to be a subject of the King of France and prince of the blood of France, and excluding them and their descendants from the succession.Since 1589 and the death of the last Valois king Henry III, the heir to the throne by primogeniture and male collaterality was his cousin in the 21st degree, Henry of Navarre.
