 In 2002 the constitution was adjusted to allow siblings of the reigning Prince and their descendants to succeed to the throne if the sovereign lacked legitimate descendants, and Christian thereupon became 11th in line of succession to the Monegasque throne.When Albert succeeded on the death of Rainier, Antoinette was no longer the sibling of the sovereign, so she and her children lost their places in the line of succession.They and their descendants do, however, remain eligible for selection by the Crown Council to accede if the current line fails.
