The Notwithstanding Clause

Paul Martin has gone and done it. In last evening's debate he promised a constitutional Amendment to End Federal Ability to Invoke Notwithstanding Clause. Is this really "the boldest defence of rights and freedoms in Canada since the creation of the Charter of Rights and Freedoms in 1982"? Or is it an abdication of responsible government and a concession to American-style judicial supremacy? According to The Potent Pew, Martin himself has not been consistent on this point. Will this new initiative win him more votes? Stay tuned.
