One of the leading arguments the pro-Brexit, anti-Equal marriage unionist DUP have used to say that the marriage laws in the rest of the United Kingdom do not apply here is that the EU don't define marriage that way.
Today the Advocate General of the European Court has said the "definition of marriage has now evolved to include same-sex couples". He also calls on all member states to recognise same-sex marriages that have taken place in other member states. The word spouse most now not only apply to opposite sex couples.
This may course interesting IF the Northern Ireland Assembly can get back up and running. Currently same-sex marriage from other parts of the UK are relegated to civil partnerships. However, if the right of spouses of any marriage have to be recognised that will have to change. It means that same-sex marriages would have to be recognised as marriages in Northern Ireland and takes us one step closer to hopefully allow same-sex marriages to take place here as well.
No doubt the DUP will try and come up with some other excuse quoting their rapidly shrinking list of countries that do not recognise same-sex marriage. Saying after years of quoting EU court definitions that we are about to leave and that should now apply to us now. Bear in mind that the DUP have uses Great British law when it agrees with them, over marriage they used Irish law after the British didn't along with EU. Now that even the EU laws are changing where next?
The DUP are losing the argument and soon and very soon I hope to see marriage equality, not just same-sex marriage come to Northern Ireland.
