The polygamy ruling was just restricting Utah from prosecuting people for cohabitating, it did not keep them from prosecuting bigamy. It was based on and brought by the people on that Sister Wives show, IIRC. They were being charged even though he’s only legally married to one of those ladies. The judge felt that Utah’s law went too far.
BUT, it will be construed to mean that they MUST be recognized, just as Lawrence v. Texas, made sodomy "legal" nationwide, was cited extensively to force counterfeit marriage on multiple states.
Yes, this is the Lawrence of the polygamists.
