It would be no more than speculation on my part to say what judges in Canada should do. It would come as no surprise if they did consult international documents. We have a long tradition of documenting human rights too. They are actually all handled in the same way. That helps when interpreting situations here in our country. Referring to the declaration does not mean that judges are going to change their approach to section 35 in any fundamental way. But, as I have already said, this is nothing but speculation.
