My next question is the natural follow-up to what you have just said, which is good.
I am on page 4 of the French version of the document. It talks about Canada's human rights obligations. At the beginning of the paragraph entitled "The principle of non regression", you say there is a "strong presumption of the impermissibility of any retrogressive measures". The rest of your quotations refer us to footnotes. Would you be so kind as to tell us the source of that quotation, about the "presumption of the impermissibility of any retrogressive measures"?
