In the article, I thought it was interesting that the Canadian Justice said suicide is not itself illegal.
If I remember correctly, I believe the opposite is true under US criminal law, where suicide is technically illegal. Thus, if you attempt suicide and fail, in theory a homicide charge could be brought against you. Obviously, if you succeed in suicide, the charge would be moot.
The effect of the ruling will not be immediate, because Smith suspended it for one year in order to give Parliament time to take whatever steps it sees fit to draft and consider new legislation.
But in the meantime, Smith granted Taylor a constitutional exception to seek physician-assisted suicide if she chooses to end her life.
