As far as I can tell from a (not exhaustive) Google search, polygamy remains illegal in the US.
Recent appeals against bigamy laws in Utah succeeded only insofar as clarifying that simple cohabitation per se by multiple partners is not a crime (assuming everyone is of legal age, not being coerced, etc.).
Phrased differently, while it is no longer a crime for any number of people (with any permutation of genders) to co-habit, it remains a criminal offence to receive, or apply for, more than one marriage license.
My question, then, is on what grounds might ‘the courts’ justify continuing to uphold such a law? What compelling state interest is met by denying marriage licenses to polygamists and by making it a crime to obtain more than one? I note explicitly that laws directed against individuals who would obtain multiple licenses for the purpose of committing fraud, or to subvert laws outlawing sex with minors, etc., can be created separately and specifically to address such matters and, in any case, are independent of polygamy? At the end of the day are laws prohibiting polygamy not fundamentally based on moral objections in the same way that bans on same-sex marriage are?
(I recognize that this may be better suited for GD. However, I am hoping to obtain ‘factual answers’ to my question, or at least educated guesses based on facts from legal history and precedents, the COTUS ‘approach’ to such matters, etc.).
Thanks!
