In Ahmed Ali Al-Kateb v. Godwin, for example, two judges
of the High Court of Australia came to radically different conclusions.
One judge regarded the view that the Constitution should be read con-
sistently with the rules of international law as ‘heretical’,
213
while another
declared that ‘opinions that seek to cut off contemporary Australian law
(including constitutional law) from the persuasive force of international
law are doomed to fail’.

This debate reflects differing approaches to
constitutional interpretation.

The Indian Constitution refers only in the vaguest of terms to the pro-
visions of international law,

Simpson and Williams have concluded that ‘[j]udges will approach extrinsic materials,
such as international law, differently depending on whether they favour rigidly applying
the Constitution as originally drafted and intended or, at the other extreme, updating the
instrument for societal change consistent with a vision of the Constitution as a “living

tion’, 11 Public Law Review, 2000, pp. 205, 226.
