Would anything change if Prince Charles *wasn't* his father?

Ahhh! Double-post! Sorry about that :smack:

Charles IV nothing – as recently as 1857, Isabel II of Spain’s kid, who later became Alfonso XII, was probably not the son of Isabel’s husband, the King Consort Francisco de Asís, who was as queer as a three-peseta bill. It’s now thought he may have been the son of Isabel’s captain of the guard, a Catalan named Enrique Puig i Moltó.

Of course, it’s a little late to do anything about it, unless you care to refight the Carlist Wars; in any case, the current Constitution declared King Juan Carlos I (Alfonso XII’s great-grandson) to legally be “the legitimate heir of the ancient dynasty.”

The historical issue, as I see it, is that the law required actual paternity. If the putative father wanted to contest it, whatever he might offer in the form of evidence (his own repudiation for example) would be considered. DNA tests are merely another form of evidence – considering them in determining paternity doesn’t reach back centuries to give the ancestors powers they didn’t have and doesn’t mean that the law of succession “relies” on paternity tests.

It’s the same in criminal court – a jury today considering a charge of murder is doing exactly the same thing as a jury back then would be. The fact that DNA evidence is available now and wasn’t then does not mean that today’s jury is doing something materially different from what yesterday’s jury was doing.

But in this case, wouldn’t Alfonso XII’s claim to the throne have come through his mother, regardless of who his father was? Or would his bastardy have made him ineligible (although that would be a different issue)?

How on earth could these rumours have started? :dubious:

In the common law of trusts and estates, “heirs of the body” does mean legitimate, actual genetic (“natural”) descendants. No adoptees allowed. No bastards allowed. Furthermore, it implicates the rules of primogeniture, meaning that only one person at a time will inherit, just as with the throne. It would seem to me likely that this is the meaning implicated by the Act of Settlement.
