Yes, OP, and it is the whole world, if we look at CEDAW and the potential implications.
Which is to say, this ruling threatens all protections women have ever won in law:
'Crucial to understanding this is the Convention on the Elimination of Discrimination Against Women (CEDAW). This is an international treaty adopted in 1979 by the UN - effectively an international bill of rights for women.
Giggle’s defence argued that Australia’s ratification of CEDAW obliges the State to protect women’s rights, including single-sex spaces.
So today’s ruling in favour of Tickle will be significant for all the 189 countries where CEDAW has been ratified - from Brazil to India to South Africa.'
