Principle: The Federal Court held that Adorna Properties had obtained an indefeasible title under the principle of immediate indefeasibility, even though the land was acquired through fraud. This decision was highly controversial because it appeared to protect the fraudulent party.

Significance: This case established immediate indefeasibility in Malaysia, where a purchaser's title is indefeasible upon registration, even if it was obtained through fraud.

Principle: The Federal Court overturned the previous ruling in Adorna Properties, re-establishing the principle of deferred indefeasibility. This means that a registered title is only indefeasible if the new owner was not involved in fraud or forgery.

Significance: This case corrected the earlier misinterpretation of the Torrens System by clarifying that indefeasibility does not protect titles obtained through fraud, reinforcing deferred indefeasibility.

Principle: The court applied the mirror principle, affirming that the land register reflects the actual legal ownership. Since the purchaser had registered their title, it became indefeasible, despite the earlier unregistered transaction.

Significance: This case emphasizes the mirror principle, which holds that the land register should accurately reflect the state of ownership and any interests affecting the land.

Principle: The mirror principle was reinforced, establishing that only registered interests are protected under the Torrens System, while unregistered interests are not recognized.

Significance: This case confirmed the reliability of the land register under the Torrens System, ensuring that registered titles are conclusive.

Principle: The curtain principle was applied here, meaning that certain unregistered equitable interests are "curtained off" and do not affect a registered proprietor who purchases in good faith. The court held that the registered owner’s title was indefeasible, and the unregistered equitable interest was not binding on them.

Significance: This case illustrates the curtain principle, where the registered title protects a bona fide purchaser from hidden equitable interests not noted on the land register.

Principle: The court held that Walker's registered title was indefeasible, despite the fraud. The principle of indefeasibility was reinforced, meaning that the registered titleholder's rights could not be challenged except in very limited circumstances (e.g., actual fraud).

Significance: This case highlights the protection offered to registered proprietors under the Torrens System, even when the title was acquired through a fraudulent transaction.

Principle: The court discussed the exceptions to indefeasibility under the Torrens System, stating that the registered title could still be challenged if fraud, misrepresentation, or procedural irregularities are proven.

Significance: This case is important for clarifying that indefeasibility is not absolute and can be set aside in cases of fraud or other recognized exceptions under the National Land Code.

Principle: The court upheld the indefeasibility of title, ruling that once a title is registered, it is protected, and no claims to the land can be made unless the registered proprietor is directly involved in fraud.

Significance: This case reinforces the Torrens System by upholding the idea that registered title is secure and that exceptions only arise in specific, narrowly defined circumstances, such as direct involvement in fraud.
