They could design/enact a law putting restrictions on late term abortions, or other restrictions. If they got passed, there is no law of nature that says a supreme court wouldn't uphold part of it.
They are not going to be able to make abortions illegal, but they can work to make it much more difficult.
As far as the Charter, the Harper gov't opposes the Charter, Fantino opposes the Charter, except for when police use it to protect themselves.
The Charter means nothing, in certain cases. I saw the Charter violated a few hundred times by the State at the G20. And no one can do a damn thing about it. Its a tough lesson to learn in the school of hard knocks, that in fact, the Charter doesn't work, if the State-Police-Prosecutors-Politicians-Media decide to ignore the Charter.
If the State is controlled from top to bottom, they can violate the Charter, and in fact nothing can be done about it. G20 proved that thesis.
The only thing left is class action lawsuits, which again do nothing.
Could they use that same model to be applied to abortion and other areas in various ways?
