Almost every dispute over registered land in Papua New Guinea begins with this case. It decides that the register is what counts, even when the process behind it was flawed.
Mudge and Mudge v Secretary for Lands, the State and Delta Developments Pty Ltd [1985] PGSC 13; [1985] PNGLR 387; SC308
Supreme Court, Waigani — Kidu CJ, Pratt and Woods JJ, 6 December 1985.
What happened
The Mudges challenged the grant of a State lease to Delta Developments, which had been registered under the Land Registration Act. In the National Court, Bredmeyer J found that there had been breaches of the Land Act in the way the lease was granted, but refused to order forfeiture. The Mudges appealed, arguing that a lease granted in breach of the statute could not stand.
What was argued
The appellants said that irregularities in the exercise of the statutory power to grant the lease went to its validity, and that the courts should not allow an unlawfully granted interest to be protected by the register. The respondents said that Papua New Guinea had adopted a Torrens system of title by registration, under which the registered proprietor’s title is conclusive unless one of the statutory exceptions applies. A preliminary point was also taken that the Secretary for Lands, a public service office without corporate personality, could not be sued as such.
What the Court decided
1. Registration of leases under the Land Registration Act is effective to vest an indefeasible title in the registered proprietor, subject only to the exceptions enumerated in section 33. Frazer v Walker [1967] 1 AC 569 and Breskvar v Wall (1971) 126 CLR 376 adopted and applied.
2. Accordingly, notwithstanding that a State lease may have been issued irregularly and in breach of the Land Act, registration under the Land Registration Act confers an indefeasible title.
Kidu CJ also agreed that the Secretary for Lands, not being a corporate entity, was an incompetent defendant.
Section 33(1) provides that the registered proprietor of an estate or interest holds it absolutely free from all encumbrances except, among others, in the case of fraud. Section 33(2) adds that the operation of the section is not affected by any other person’s estate or interest which, but for the Act, might be paramount.
Did it make new law?
The Court affirmed the result reached by Bredmeyer J and, for the first time at Supreme Court level, adopted the Privy Council and High Court of Australia statements of immediate indefeasibility as part of the law of Papua New Guinea. The judgment, which relied on Assets Co v Mere Roihi [1905] AC 176, treats the fraud exception as actual fraud by or brought home to the registered proprietor, consistent with Torrens authority elsewhere.
The constructive fraud debate
Eight years later, in Emas Estate Development v Mea [1993] PNGLR 215, a majority declined to apply indefeasibility where a lease had been forfeited irregularly and regranted, and questioned whether the doctrine suited Papua New Guinea. A line of decisions has since treated serious statutory irregularity as constructive fraud within section 33. Others, most recently Dick v Investpac Ltd (2024), describe Mudge as “the root authority”, hold that fraud means actual fraud, and regard the wider view as contrary to overwhelming Torrens authority. The Supreme Court has acknowledged the two opposing views without a five-judge resolution.
Why it matters
A registered title is the starting point. A party challenging it must bring the case within section 33, and a claim of fraud must be pleaded with particulars and proved.
Irregularity alone is not enough on the Mudge view. A challenger relying on defects in the grant must persuade the court to follow the Emas Estate line, and should expect the point to be contested.
Sue the right defendant. Proceedings go against the State or the Registrar of Titles, not a public service office.
What it does not decide
Mudge does not hold that registration can create an interest the State had no power to grant at all. In 2026 the Supreme Court upheld a finding that a registered lease over sea and seabed conferred nothing, because “a stream cannot rise higher than its source”. Nor does it address unregistered equitable interests or customary land, which fall outside the Act.
Recent cases applying it
- Dick v Investpac Ltd [2024] PGSC 114; SC2642 — Mudge as the root authority on the fraud exception; the registered proprietor’s indefeasible title meant that a procedural unfairness in the process behind registration gave no relief.
- PNG Forest Authority v Sukiri Investment Ltd [2026] PGSC 12; SC2855 — Mudge argued for a lease over the sea; rejected because there was no lawful power to grant title to that area.
- Rawali v Kob [2023] PGSC 77; SC2423 — the registered proprietor holds an indefeasible title, which may be set aside only through a successful action for fraud.
- Peyape v Waiya [2021] PGSC 32; SC2109 — the Court set out the two opposing views represented by Mudge and Emas Estate.
