Everyone needs to remember that if, and it's a big if, the Romanian monarchy is ever restored, it will be the Romanian government of the day that will decide who the monarch is and what the line of succession looks like. In a constitutional monarchy, that's how it works (just ask The King of Sweden...
)
As long as there is no royal Constitution, the Royal House is an autonomous entity established and organized by Fundamental Rules "enacted by the hand of King Michael I, Sovereign Head of the Royal House of Romania (Hohenzollern-Sigmaringen), by the Grace of God and jure sanguinis, Crowned King of Romania" as is stated in the preamble. In all and everything the Republic of Romania follows this document as it is Margareta von Hohenzollern-Sigmaringen who is the one almost-but-not-yet treated as Queen of Romania. She. And not Mr Smith or Mrs Jones.
The same preamble stresses: "This document shall have its validity and power upon signature, by the King’s hand. By this document, all earlier statutes and all privileges, styles, titles, rank and rights of Dynasts or their descendants are revoked."
In an Annex to the Fundamental Rules the King adds a request to the Nation and to Parliament:
Under the full powers vested in me as
Head of the Royal House of Romania,
And in pursuit of My duty to history and
to my Family heirs,
In full conformity with the values and
principles of the European Union which
grant everyone the right to express his
identity and aspirations,
And acting on My own free will,
MAKE THE FOLLOWING
DECISIONS PUBLIC:
1. My eldest daughter, The Princess
Margareta, is to be my successor and
Head of the Royal House of Romania,
after my death. If the Romanian Nation
and Parliament were to decide to
reinstate the Monarchy as the form of
government, I ask the Parliament to cease
to implement the Salic-law as the form
of succession, which does not correspond
either to the elementary rights in Europe
today, or to the values of Romanian
society. Until these events should come
about, The Princess Margareta will
remain, after my death, Head of the Royal
House of Romania and Custodian of the
Romanian Crown.
Another complication in the case of Nicholas is that his marriage needed consent:
Article 7
1) The marriage of a member of the Royal House of Romania
shall be subject to the consent of the Head of the Royal House
of Romania in order for it to have dynastic significance.
2) A marriage that does not comply with paragraph (1) above
shall not be recognized dynastically for any purpose and shall
result in the forfeiture of all accompanying rights, honours,
privileges and prerogatives as defined by this Statute.
Of course Nicholas will argue the membership was already revoked by his grandfather (a decision he contests) and so he did not request his aunt Princess Margareta for consent. But did he still consider himself a Prince of Romania (after all he fights the loss of membership) this marriage has ended it all, by his own act and deed.
Or Nicholas
did formally request his aunt Princess Margareta for consent indeed, but the reaction by Palais Elisabeta maybe was that a consent was not requested nor to be given by the Custodian of the Crown since the request is not about an intended marriage by a member of the Royal House.
