You do realise that the Infanta Christina and her husband were made Dukes of Palma de Mallorca by her father Juan Carlos and it was her brother Felipe who revoked the title?
The title was conferred to Christina be revoked because of a scandal her husband now is convicted for, while she was not prosecuted at all. I think that constitutes a precedent.
I cannot think of any reason why Luis Alfonso's grandmother was made Duchess of Franco other than that she was the daughter of her father. It was certainly not based on her personal merits.
That doesn't mean she is a bad person, just that she did nothing extraordinary to deserve such an honour. Revoking the title might just be part of the healing process Spain had to go through since the end of dictatorship.
1. I would have no qualms with the government's position regarding re-interring Franco's body for the reasons stated.
2. I find it absolutely nonsensical for a government entity to suggest revoking a title or an honor bestowed by a former king or head of state. In this regard, the former king, Juan Carlos, conferred the title. Therefore, it should be he who revokes said title upon submission by interested parties requesting said revocation. However, Juan Carlos is no longer king and cannot revoke the title/honor accordingly. In other words, leave things be or as they are. Perhaps, the government will allow the title to die out.
Furthermore, the suggestion of revoking a title/honor bestowed on a person decades ago for whatever reason seems spiteful and petty in the least. Franco's daughter wasn't dictator but so was her father. Guilt by association, in this case family, is just an utterly trivial matter.
1. After several debates, the spanish government decided at last that Generalissimo Franco should be exhumated and casted out of Valle de los Caidos.
The Franco family has 15 days to tell the government where they want Franco to be reburied or the government will choose the place.
The Government claims that a dictator should not be buried in a public building .
2. The article claims that the government is thinking of revoking the Franco ducal title.
Such title was conferred by Juan Carlos to Franco's daughter.
Can the government revoke a title conferred by a king or should we understand it as a pressure from the cabinet for the king to act accordingly to the government's wishes ?
Is there any other case of depriving someone from a title, except for the dukes of Palma ?
3. A rather ignorant article on genealogy and titles, calling Henri duke of Paris or Jean-Christophe as head of the napoleonic cause and descendant of Emperor.
