Okay, so a blue state steps in to make themselves a safe haven. Conservative courts sue and take cases up to the supreme court to force their will on them. Said blue state then says 'I believe the supreme court ruling is invalid and will not adhere by it'. What exactly do you think will happen?

And for reference, there has already been trends of this occurring. The Texas bounty hunter law for women who have abortions is an example, where they have tried to sue other states for records pertaining to abortions (See: Texas vs Seattle Children's Hospital).
