The problem is precisely this: they have more value of international treaties or laws of a state? («la question est donc de savoir si un traité de droit international [toujours en vigueur] est une norme supérieure aux lois fondamentales»).
The Parliament of Paris experienced such waivers, as well as the parliaments of French provinces.
The answer is that the «Lois Fondamentales du Royaume de France» are ABOVE the King himself and the parlements.
The Foreign Powers had no right to dispose of the Crown of France.
Louis XIV had no right to dispose of the Crown of France.
Philip V had no right to dispose of the Crown of France, either for himself or for his descendants. The waiver is not legitimate, it can not have legal force.
Philip V, meanwhile, has never recognized the validity of waivers signed under duress of England. In 1726, he wrote to the Parliament of Paris to be proclaimed King, «in case of death of the King of France his nephew, ordering him as successor to the crown by right of birth and by the fundamental laws of the State, until he can take possession of the kingdom» («en cas de mort du roi de France son neveu, lui ordonnant comme successeur de la couronne par le droit de sa naissance et par les lois fondamentales de l'État, en attendant qu'il puisse aller prendre possession du royaume»).
Philip V of Spain is the heir to the throne of France.
It is not a matter of having a party to the Court that supports him or satisfy the desires of the Foreign Powers. The rights of Philip V were sacrosanct.
In this hypothesis, in which Louis (XV) dies from measles in february-march 1712 along with the rest of his immediate family, the hypothetical Treaty of Utrecht would have been different: Philip V of Spain at that time already had two sons and Queen Maria Luisa of Savoy was pregnant for the fourth time.
The Foreign Powers would probably have recognized his rights of succession to the Crown of France on condition that he had abdicated the Crown of Spain in favor of his second son (possible for the laws of succession of the Spanish kingdoms).
Today there is still a «Querelles dynastiques françaises».
Today, the rights to the Crown of France claimed by alleged Bourbon-Orlèans, are anything but real. In fact they are not direct descendants of Louis XIII, but they have at most one female offspring from the branch of Condé.
In fact Louis Philippe Joseph d'Orléans (1747-1793), known as "Philippe Egalité", was the son of a cocher!
«Vous savez bien, Mirabeau, que ces titres de prince et d’altesse ne me conviennent pas, que je les ai reniés depuis longtemps, et que, depuis longtemps; je ne rougis plus de Montfort le cocher» [see Journal des débats and Barnave of M.Jules Gabriel Janin].
Recommended by an old friend of shady dealings, Louis Pierre Manuel (which was so important in the difficult day on the 10th of August and we remember directly or indirectly to the death of the Marquis de Mandat, head of the National Guard who was in defense of the Tuileries Palace), but presumably for cowardice, the self-styled Duke of Orleans, having before their eyes the abyss toward which had led the King and his family, on September 15, 1792, obtained from the Commune de Paris, the act he himself had requested that a new name, Egalite:
«Sur la demande de Louis-Philippe-Joseph, prince français,[...] le procureur de la commune entendu, arrète que Louis Philippe Joseph et sa postérité porterons désormais le nom de famille Égalité[...] signé Boulo, Président, Colombeau, Tallien secrétaire».
On the same day (or other sources for February 10, 1793), rising in the tribune of the Jacobins, wearing a red cap, said:
«Je dois le jour aux liaisons impudiques de ma mère avec un valet (le cocher LEFRANC), le feu duc d'Orléans, père de celui qui semble être le mien, n'a jamais voulu me reconnaitre, et mes inclinaisons de sans culotte me persuadent que ce n'est pas le sang des Bourbons qui coule dans mes veines, je demande un nom qui me replace dans la classe du peuple», namely that he recognized his adulterous birth, due to relationship that his mother had had with the valet/groom LEFRANC, and that his attitudes as sans-culottes and the lack of similarity between father and son, had convinced him that it was not the blood of the Bourbon that flowed in his veins!
The alleged illegitimate birth is also legitimacy from the chronicles of the time on the loose morals of the Duchess of Orléans, Louise Henriette de Bourbon-Conti; she had all the audacities of vice and tried her lovers among the servants, indifferent to all the scandals, imperturbable all the insults.
At her death on February 9, 1759, was found a sort of testament with her seal: it contained a list of her lovers, and for each a compendium of their "quality" (Mémoires de la Marquise de Créquy).
The same duchess has written:
"Monseigneur d'Orléans,
"Vos prétendus enfants,
"Sont l'objet du mépris
"De tout Paris!"
To substantiate the hypothesis of a bastard birth there are also the memoirs of the Baroness d'Oberkirch, that writing about Louise Marie Thérèse Bathilde, Duchess de Bourbon and Princess of Conde, sister of Philippe Egalité, confided that «Je suis tout Condé et je n'ai rien d'Orléans...».
Finally, Philippe Egalité has publicly renounced for himself and his descendants, to any rights to the French throne, as he himself stated in a letter written in his own handwriting, the newspaper Moniteur on December 7, 1792:
«Je déclare que je déposerai sur le bureau ma renonciation formelle aux droits de membre de la dynastie régnante, pour m’en tenir à ceux de citoyen français. Mes enfants sont prêts à signer de leur sang qu’ils sont dans les mêmes sentiments que moi».
But at the time of this release there was a Constitution duly approved, which was to replace the millenarian «Lois Fondamentales du Royaume de France», as the new constitutional monarchy was going to replace the millenary absolute monarchy.
