One of the implications I believe beyond the United States is I think the Supreme Court of Canada which has moved as far to the left post Morgantaler under Justice Dickson as the SCOTUS has moved to the right might be inclined to lay down some markers in front of Canadian social conservatives to let them know not even to think about bringing the abortion issue back up in Canada. On which e is easy to layout in front of the Socons would be a completed throwing out of Bill C-36 with strong notice to Parliament that given the long line of decision sex work cases going back to Bedford, the Prostitution reference, and Hutt in the 70s they never want to see sex work related laws before the court ever again in their lifetime.
**Yes I know about the notwithstanding clause in Canada and yes many people here like Mandrill think Bill C-36 is toast anyways but I think the SCC might be more inclined to just take the whole thing down in a very broad ruling based on sexual freedom and freedom of association akin to the Labaye Swingers Club obscenity case.
Where I think this is a jut punch for the SCC is the old 1997 Malmo-Levine Marijuana case i.e. Parliament and legislatures can criminalize anything they want based on paternalism and protecting "core values" looks less and acceptable to today's public 25 years later in light of the US gutting to the right to abortion. Although as Alan Young points the SCC was trying to underdo Malmo-Levine the day it was written and Bedford with it's focus on gross disproportionality comes out of the Malmo-Levine decisions(Something Young claims the SCC basically made up in 1997). Also Malmo-Levine despite ruling for the govt probably did lead to Parliament decriminalizing marijuana eventually.
