Can effective control supply what an informed cession did not?

Not in the simple sense that “possession cures everything”. Crown authority was initially limited and resisted, while traditional prescription required long, uninterrupted and undisputed possession. But over time effective government, international recognition and constitutional continuity made Crown sovereignty an entrenched legal fact. That process explains durability; it does not retrospectively prove the February 1840 cession.

1. First separate effectiveness from consent

A state can exercise power without proving that every person or political community originally consented to its rule. That is a descriptive fact about states. But it creates a legal danger if two different propositions are collapsed:

Effective government can become evidence of sovereignty. It does not alter the words spoken, translated or understood at Waitangi in February 1840.

2. What would “prescription” have required in the law of nations?

One possible theory is prescription: an asserted territorial title becomes legally secure after sufficiently long possession that is not effectively disputed.

This was not invented by twentieth-century courts. Emer de Vattel’s Law of Nations, a major eighteenth- and nineteenth-century public-law text, described prescription among nations as depending on long possession that was uninterrupted and undisputed. He specifically distinguished such possession from possession continuing only a few years.

A near-contemporary British text, Travers Twiss’s 1846 work on the Oregon territory, likewise described settlement as capable of resolving into prescription only where possession became sufficiently established and acquiesced in.

3. The early Crown did not actually exercise comprehensive control over New Zealand

The factual record creates another problem for an immediate-effectiveness theory. Official New Zealand histories acknowledge that in the 1840s the colonial government had little or no authority in many parts of the country. Extending Crown authority beyond pockets of European settlement initially depended on negotiation and persuasion because Hobson had a small budget and tiny police and military forces.

The population balance matters too. In 1840 Māori greatly outnumbered settlers. Large parts of the country remained under the practical authority of rangatira and hapū, with colonial government concentrated around a small number of settlements.

4. Nor was Crown authority undisputed

Hōne Heke’s repeated cutting of the flagstaff at Kororāreka and the Northern War of 1845–46 are especially important for this part of the audit. The Waitangi Tribunal characterises the flagstaff actions as a challenge to Crown encroachment on Ngāpuhi tino rangatiratanga. It found that the Crown used military force in the conflict to impose the sovereignty it believed it had acquired in 1840.

Later resistance was not confined to Te Raki. The Kīngitanga emerged in the 1850s partly from concern over land loss and the need to create a Māori political authority capable of resisting settler governmental expansion. The wars of the 1860s and subsequent confiscations are further evidence that the expansion of Crown authority was not simply a peaceful nationwide acquiescence beginning in 1840.

If prescription requires long and undisputed possession, armed and political resistance matters. It cannot simply be redescribed as consent.

5. Modern “effectivités” doctrine helps classify the problem — but must not be applied backwards mechanically

The 1928 Island of Palmas award famously treated continuous and peaceful display of state functions as a major criterion of territorial sovereignty. The 1933 Eastern Greenland judgment likewise said that a sovereignty claim based on continued display of authority requires both an intention to act as sovereign and an actual exercise of authority.

Modern international-law decisions distinguish legal title from effectivités. Where a clear legal title exists, actual administration generally confirms rather than displaces it. Where no clear title exists, effectivités may carry much greater weight. Where effectivités are said to override an earlier title by prescription, acquiescence or tacit recognition becomes crucial.

But there is an important methodological limit: under the intertemporal principle, an event in 1840 must be evaluated primarily by the law applicable to it at the time. Palmas and Eastern Greenland are therefore useful later formulations of the doctrine, not retroactive statutes governing Hobson.

6. Foreign recognition strengthened Britain's external position

The French episode at Akaroa is useful because it shows how interstate recognition differed from Māori consent. France had supported plans for a French settlement, but after Captain Lavaud arrived and encountered Britain’s already-declared claim, he accepted that a French colony could not realistically be established. British magistrates and governmental acts followed at Akaroa.

That episode helped eliminate a possible rival European state claim to part of New Zealand. It is relevant to Britain’s external international position.

7. This reveals why the international-law and domestic-law questions diverge

International territorial doctrine asks whether one state’s title is sufficiently established against competing sovereign claims. Domestic constitutional law asks which institutions the courts themselves recognise as having authority to make binding law.

By the late twentieth century, New Zealand courts were explicit about the latter question. In Berkett v Tauranga District Court, Fisher J accepted that assumptions underlying the original proclamations could be questioned historically, but said this had not displaced the general recognition subsequently afforded to them. More importantly, he held that courts do not delve back into history to establish Parliament’s pedigree in order to test the validity of a current statute.

Brooker v Police applied the same principle in 2017: a claimed mid-nineteenth-century clash of sovereignties cannot be used in a New Zealand court to invalidate an Act of Parliament. The Supreme Court has likewise rejected arguments that Māori sovereignty creates a unilateral exemption from the jurisdiction of New Zealand courts.

8. So did effective control “supply” the missing cession?

Not as a substitute transaction. We have not found a rule by which later Crown administration can be rewritten as the February consent Hobson claimed.

But effectiveness matters enormously to the later legal result. Crown institutions persisted. British and then New Zealand legislatures made law. Courts exercised jurisdiction. Colonial administration expanded. Foreign powers dealt with Britain on the basis that New Zealand was British territory. Settler population and state capacity grew. Military and administrative power extended further across the country.

Over time those facts made the asserted sovereignty increasingly difficult to treat as merely provisional.

Effectiveness did not prove the original cession. It helped turn the Crown’s asserted sovereignty into an entrenched constitutional fact.

9. That finding also explains why “no cession = no law today” does not follow

The historical source question remains capable of serious scrutiny. The Tribunal’s non-cession finding does not disappear merely because the state became effective.

But present legal validity is operating through a different mechanism. A functioning legal system maintains itself through institutions and rules of recognition: courts identify Parliament as the law-making authority and apply its enactments. They do not make the validity of every statute depend upon re-proving the Crown’s original acquisition in 1840.

That is why the two propositions can coexist:

Neither proposition logically cancels the other. They answer different legal questions.

That takes us directly to Part 6. We can now identify what modern courts actually treat as settled, what they still permit to be historically contested, and where the legal boundary lies between Treaty/rangatiratanga claims and a challenge to the existence of the state itself.
