I don’t expect the Smith Bill to be passed without some tweaking. What I hope is that the underlying basis of the Sex Discrimination Act and the Family Law Act, plus existing Human Rights law will not be underminef to erect a second class status for SSM.
There is such a thing as the Acts Intepretation Act to assist the courts in interpreting the law, including its object and purpose.
Despite the careful crafting of the Bill and anticipated amendments , challenges can never be ruled out. That is a sign of a robust society and not to be feared. But you can’t compare it with a Constitution drafted in the 19th century in such different historical circumstances,
Absent Abbott and his damned plebiscite, all of this could have been resolved so much sooner.
Fears need to be articulated beyond the what if category.
