From above link:
"Application of strict equality requirements leaves only the margrave and his brother as males of the Saxon house.
However, the Margrave deemed that the Afifs (as Princes of Gessaphe) were equal marriage partners and that Alexander was his immediate heir. This the Margrave was entitled to do. Furthermore, all of the living male-line dynasts affirmed the decision of the Margrave.
Semi-salic law would lead to either sister of the margrave; but there are no lines issued from them that satisfy the equality requirements, hence the headship of the house would pass to the lines issued from the margrave's paternal aunts.
Interesting how you commented that the first link I posted is unreliable as it came to the conclusion that Prince Alexander is now Margrave of Meissen while you expressed no such reservations about the reliability of the second link I posted, presumably because it calls into question the equality of the Afifs (a family which the Margrave, as Head of House, decided did indeed meet the equality requirement).
These aunts are Margarete (1900-62) married to prince Friedrich of Hohenzollern, Maria Alix (1901-90) married to prince Franz Joseph of Hohenzollern-Emden, twin brother of the latter, and Anna (1903-76) married to Joseph of Habsburg-Lorraine, palatine of Hungary, all of whom had children. Margarete being the eldest, the heir would be Friedrich Wilhelm of Hohenzollern-Sigmaringen (b. 1924), failing him his son Karl Friedrich (b. 1952).
Thank you for copying and pasting something that I had already read at the original link.
If one discards equality requirements completely (but maintains semi-Salic law), then Timo's son Rüdiger and his line will succeed at the next generation, no matter which of the margrave or his brother survives last."
But one cannot discard the equality requirement. Prince Timo contracted three unequal marriages. In doing so he guaranteed that his son Rudiger and daughter Iris, the issue of his first union, have as their surname "Prinz(essin) von Sachsen Herzog(in) zu Sachsen" but that they do not possess and can never possess the actual royal title of IKH Prinz(essin) von Sachsen Herzog(in) zu Sachsen as they are morganatic descendants of the Royal House with zero chance of ever having succession rights.
Conversely, the late Margrave ruled that the marriage of Princess Maria Anna was equal, all the male-line Saxon dynasts affirmed his decision, and, therefore, Maria Emanuel was succeeded as Head of House by his adopted son Prince Alexander of Saxony, eldest son of Princess Maria Anna.
So you agree it's as I stated it: if the equality requirement is discarded, then prince Ruediger is the heir, if not, then it's a prince of Hohenzollern. In any case, it is not "Prince" Alexander.
Actually, I do not agree that it is as you stated nor do I agree with the interpretation of the House Laws given in the second link I posted.
I obviously agree with the interpretation of the Saxon House Laws given by the late Margrave of Meissen as laid out in the first link I posted. I.e. that Prince Alexander of Saxony is the new Head of House.
