When the minister appeared here specifically on this issue he said, and I'll read from the blues for all of us:
Of course I have carefully considered the Canadian Charter of Rights and Freedoms and the Canadian Bill of Rights in respect of the totality of these new dangerous offender reforms, and I am satisfied that they are fully constitutional. These measures have been carefully tailored to provide a prospective, targeted, and balanced response to the real and pressing problem posed by these dangerous offenders.
I leave that with the committee. That is in writing. They're the minister's words from the transcript of the committee. He has certified that they're constitutional, and going beyond that would be extremely unusual.
