Food for thought…
A 1988 amendment to Article 121(1) of the Federal Constitution to remove judicial power from judges did not have the desired effect, Chief Justice Tengku Maimun Tuan Mat said.
Constitution must be interpreted in light of its historical and philosophical context, underlying fundamental principles; as in the Westminster’s model, a separation of power among the ‘branches of government’; inherent within, the judiciary role as the ultimate-arbiter corollary to the ‘rules of law’; in no-way inimical to democratic government; but also to interpret statutes, as on par with the ‘sovereignty of Parliament’; thus this ‘basic structure’ cannot be abrogated or removed by a constitutional amendment; thus a feature intrinsic to the constitution itself as the supreme-law; vesting upon the judicial power to review against unconstitutional legislation, whether or not it is expressly stated; bringing about the significance that judicial-power cannot be removed from civil-courts.
Any other courts, i.e. the Syariah Courts, a creature of State Legislative creation, cannot be vested with judicial power as it is unequal to the ‘superior court’ in accordance to the constitutional provisions; repugnant even if the Parliament attempt to amend the constitution to give power to the Syariah Courts.
