Case Note: Plimmer v Mayor, Councillors, and Citizens of the City of Wellington [1884] UKPC (Privy Council, 25 June 1884)

Facts

• In 1848, John Plimmer, with Crown permission, moored an old hulk (“Noah’s Ark”) on the foreshore of Wellington Harbour to use as a wharf and store.
• After a 1855 earthquake reduced water depth, Plimmer erected a jetty extending approximately 190 feet seaward (the “yellow” portion on the plan).
• In 1855, the harbour bed, including the land under the jetty, was granted to the Provincial Government for public purposes.
• In 1856, at the Provincial Government’s request, Plimmer extended the jetty a further 112 feet (the “green” portion) and built a warehouse on reclaimed land to accommodate immigrants being introduced by the Government.
• From 1856 to 1863, the jetty and warehouse were extensively used for immigrants, with the Government and others paying Plimmer for the use.
• Between 1857 and 1861, the Government reclaimed adjacent land and built a quay, cutting away the shore end of Plimmer’s jetty with his permission. Plimmer used a temporary gangway during construction and was then allowed to connect the remaining jetty to the new quay.
• The jetty continued in use as a landing place, and in 1872 it was declared a legal quay under statute.
• Plimmer’s interest was sold to Jacob Joseph in 1875, who leased it to the appellants (claimants) for 21 years from 1879.
• In 1878, the appellants extended the jetty slightly without permission, prompting a Government letter asserting the whole wharf had been erected without authority (though this contradicted prior conduct).
• In 1880, the land was vested in the respondent Corporation by statute.
• The respondents took possession in 1882, and the appellants claimed compensation under a 1882 Act, which entitled those with an “estate or interest” in the land (or suffering loss) to compensation, with the Compensation Court able to award on reasonable and just grounds beyond strict legal rights.

Legal Issues

The sole question (as stated in the Special Case):

• Did the claimants have any estate or interest in the land on which the remains of the jetty stood when it vested in the respondents under the 1880 Act; and if so, what was the nature of that interest?

Subsidiary issues included:

• Whether Plimmer’s occupation was merely a revocable licence, a tenancy-at-will, or something more permanent.
• Whether any interest had been acquired by adverse possession (Statute of Limitations).
• Whether equitable principles could create an irrevocable interest where expenditure was incurred at the landowner’s request.

Legal Principles Adopted and Applied

The Privy Council applied equitable doctrines derived from Ramsden v Dyson (1866) LR 1 HL 129, particularly the principles articulated by Lord Kingsdown (dissenting in that case but influential here):

1. Where a person expends money on land under an expectation, created or encouraged by the landowner, that they will have a certain interest, and does so with the landowner’s knowledge and without objection, equity will compel the landowner to give effect to that expectation to prevent fraud.
2. The equity is stronger where the landowner actively requests or encourages the expenditure for their own benefit, rather than merely standing by in silence.
3. The precise form of relief depends on the circumstances: it may be a specific interest (e.g., perpetual occupation), compensation, or recouping expenditure. The interest need not be expressly defined; the court looks to what is required to satisfy the equity.
4. An executed licence that is indefinite in duration and supported by expenditure creating a legitimate expectation becomes irrevocable and effectively perpetual (analogised to cases like Winter v Brockwell (1808) and Liggins v Inge (1831) concerning licences to do works on another’s land).
5. In compensation statutes, “estate or interest in land” should be interpreted broadly, especially where the statute directs consideration of what is “reasonable and just” beyond strict legal rights.

The Council distinguished Ramsden v Dyson on the facts: here, the Government actively requested the improvements for public purposes (immigration), creating a clear expectation of continued occupation.

Ratio Decidendi

The claimants had an estate or interest in the land entitling them to compensation because:

• Plimmer’s original occupation began as a revocable licence for wharf purposes.
• The 1856 transactions (Government-requested extensions and warehouse construction for immigrant accommodation) created a reasonable expectation that his occupation would not be disturbed, rendering the licence irrevocable.
• This gave Plimmer a perpetual (indefinite) right to occupy and use the land for jetty/wharf purposes, which could only be terminated by legislation for public purposes (with compensation).
• This equitable interest was transferred to Joseph and then leased to the appellants, who retained the unexpired term as at 1 September 1880.
• The interest qualified as an “estate or interest in land” under the broad interpretation required by the compensation statute.

The 1857–61 alterations reset any adverse possession clock but did not destroy the prior equitable interest; they were consensual and left Plimmer in the same position relative to the altered jetty.

Obiter Dictum

• Adverse possession was unnecessary; the claim succeeded in equity rather than by trespass or limitation.
• Discussion of how equities are satisfied in different cases (e.g., fee simple in Dillwyn v Llewelyn, perpetual retention in Duke of Beaufort v Patrick, or mere recoupment in Unity Bank v King) — the form of relief depends on circumstances.
• Analogy to irrevocable executed licences on the licensor’s land: where expenditure is incurred and a supervening equity arises, an indefinite licence becomes perpetual.
• Comment that foreshore land (publicly owned and often improved without formal authority) naturally gives rise to expectations of more than precarious tenure when the parties deal consistently over years.
• Rejection of the respondents’ argument that 1857–61 transactions reduced Plimmer to a mere tenant-at-will by “bounty”; the dealings were mutual and consensual.

This decision is a foundational authority on proprietary estoppel (preceding modern formulations) and illustrates that active encouragement by the landowner strengthens the equitable claim.
