Succession to the French throne
In 1791 the French National Assembly drew up a new, written Constitution to which the King gave his assent, and which governed France for the last year of the 18th century monarchy. For the first time it was necessary to define formally, as a matter of statutory constitutional law, the system of succession, and the titles, privileges and prerogatives of the Crown. In debating the succession to the Crown the contemporary understanding of the law of succession was publicly clarified. It rebutted the assertion by some that the claim by the Spanish line is a late construct, made to satisfy the ambitions of princes deprived of other claims. Indeed, it is evident that the issue of the rights of the Spanish line to the French crown remained an important constitutional issue.
Constitutional amendments under the French Fifth Republic
The constitutional revision of 1974, though it was called a "small reform" when it was voted on by Congress, has profoundly upset French political action, better ensuring the superiority of the Constitution over the laws. There were 54 constitutional decisions between 1958 and 1975, there were more than 200 in the next 15 years, between 1975 and 1990. However, the problem of referral remained unresolved: it was still possible today to see a law contrary to the Constitution coming into force, with the excesses that it could carry. An independent referral to the parliamentary and executive power seemed essential, as was the case in Germany or Spain. Since March 2010, the opened ability to refer legislation to any person who, in the course of a proceeding, challenges the constitutionality of a statutory provision. This referral allows, after being filtered by the Supreme Court of jurisdiction, (Court of Cassation or Council of State) to ask the Constitutional Council to repeal this provision, if it is contrary to a right or freedom that Constitution guarantees.
