Banning incest is a public health matter. This is easy. Polygamy has been legalised without any consideration what's over of the legal and tax purposes, and potential for fraud. It is so infernally complicated that we are better off ending recognition of marriage rather than attempting to deal with it. I hope the Senate sees sense and passes this.
Northeastern married individuals can no longer receive benefits as a result of their married status, so that's mute. IIRC in the group marriage bill we required all polygamous married couples seeking legal recognition to sign a prenup so that should settle any legal issues. This was decided after extensive discussion in the Assembly. Regardless, why pass a Constitutional amendment at the Federal level in order to prevent one Region's tax and legal issues?Then what's the point of having the government recognise it at all?
