IIUC, the BHO Sr. SADO marriage was absolutely NOT a polygamous marriage IF performed in HI because the Kenya Marriage Act of 1902 did not recognize marriages that were illegal where performed due to bigamy. Under the Kenya Marriage Act, mixing marriages from three separate marriage codes was illegal and a bigamous marriage is moot in the UK and US.
IIUC, legitimation can only occur via a post-birth marriage of the parents which converts a child that was illegitimate at birth (and thus non-UK subject at birth) into a “legitimated” post-birth UK subject. There is no evidence of a post-birth marriage of SADO to anyone but Lolo Soetoro, IIUC.
What was the domicile of Sr. -Kenya or the US. I would argue Kenya since he was on a temporary visa when he stayed in the US. But it doesn’t really matter because neither the US or Kenya would have recognized that marriage to Ann.

Furthermore, any idea that a tribal marriage has to be licensed to be valid is just ludicrous. It was very easy to get married in the Luo tribe and that marriage was recognized under Kenyan law.
I submit that it might have been possible for Obama to fall on the mercy of the system in UK and actually get registered through special dispensation or court proceeding.
HOWEVER, I still see no law that made his citizenship automatic and retroactive.
