In SGH v Commissioner of Taxation,1 Gummow J stated, "Questions of construction ofthe Constitution are not to be answered by theadoption and application of any particular, all-embracing and revelatory theory or doctrine of interpretation." Whilemany Justices of the High Court have championed such a view, others, such as Kirby J, have argued for the adoption of a single, unified approach to the interpretation of the Constitution. You are required to critically analyse the two approaches to interpretation, for and against a unified approach, and clearly state and justify which of the two approaches you favour. In your argument, briefly explain the different interpretive techniques adopted by past and present Justices of the High Court and explain which, if any, of these techniques Kirby J believes should be the adopted by the High Court.
