I believe that Minister Toews said when he appeared before the parliamentary committee to discuss the bill that undue interference had not at all been a problem in the old system, but that he wanted to see a new kind of guarantee designed to protect prosecutors applied.
In future, if the Attorney General wants to intervene in a case, he will have to do so in a very different manner. As you know, Quebec, Nova Scotia and some Commonwealth countries have also adopted the system involving a director of public prosecutions.
