So, is incest still illegal?
What about 2 sisters who want to marry? Is that allowed? 2 Brothers? What about a man and his dog? Can I declare my cats as dependants? After all they are my children..

So, is incest still illegal?

Well, that's the point, or at least one of them anyway.

If "unions" are unavailable to the pragmatically partnered (like brothers and sisters, or two maiden aunts living together), it seems to me that they have to require that the "partners" meet the test of being sexually involved.

This hearkens back to the common law ground of non-consumation for an annulment.

Who's going to check?
