With the great news of the successful outcome of Obergefell v. Hodges paving the way for gay marriage across the entire USA some folks have already been begun to discuss how the outcome will build on the momentum to legalise polyamorous marriage.

This blog post from Poly in the Media quotes the dissenting opinion from Chief Justice John Roberts in which he says:

It is striking how much of the majority’s reasoning would apply with equal force to the claim of a fundamental right to plural marriage.

However, I would prefer to focus instead on the much more positive, and beautiful, words from Just Kennedy in this post from Ed Brayton’s Dispatches from the Culture Wars (one of my favourite blogs):

The fundamental liberties protected by the Fourteenth Amendment’s Due Process Clause extend to certain personal choices central to individual dignity and autonomy, including intimate choices defining personal identity and beliefs. Courts must exercise reasoned judgement in identifying interests of the person so fundamental that the State must accord them its respect. History and tradition guide and discipline the inquiry but do not set its outer boundaries. When new insight reveals discord between the Constitution’s central protections and a received legal stricture, a claim to liberty must be addressed.

It’s well accepted that it’s a significant step-up in difficulty to cope with legally recognised polyamorous relationships compared to the extension of the marriage contract to support homosexual couples. Changes to contract law and children’s services would need intensive discussion but I feel that we’re now in a society where starting those conversations will be acceptable.

For those that are still dubious have a look at the graph below which shows the ever decreasing time periods needed to effect positive social change in the USA.
