Wi Parata: where did the courts begin closing the sovereignty question?
The 1877 judgment used deeply discredited reasoning about Māori political capacity, but its more durable constitutional move was to treat the Crown's acquisition of sovereignty as a fact the colonial courts would not question.
Non-justiciability · Colonial doctrine
Wi Parata v Bishop of Wellington is notorious for describing the Treaty, insofar as it purported to cede sovereignty, as a “simple nullity” and for denying that Māori possessed a body politic capable of cession. That reasoning and its racial assumptions are rejected in modern New Zealand jurisprudence.
But for the present inquiry another part of the judgment is at least as important. The Court treated the Crown's acquisition of the country as an implied constitutional fact that could not be questioned in an ordinary court proceeding. It framed Crown dealings concerning native title as matters of sovereign or prerogative authority.
That is a crucial shift. Once the colonial court says the constitutional fact creating the court itself is not open to challenge before that court, the problem changes from evidence of cession to justiciability.
Wi Parata should not be treated as good modern authority for its denial of Māori customary law or its racist description of Māori society. Ngāti Apa later called its native-title reasoning discredited. But the broader judicial instinct not to adjudicate the validity of the Crown's foundational acquisition survived in later forms.
The bridge starts to become procedural: the court does not prove the founding act; it declares the founding fact outside the scope of ordinary adjudication.
Now rejected
The proposition that Māori custom was legally non-existent and that native title depended simply on Crown grace and favour.
More durable idea
The validity of the sovereign acquisition itself is not treated as an ordinary question a court constituted by that sovereignty will retry.
