Stranger auction purchaser protection upheld where court sale stood unchallenged; prescriptive title failed for lack of proper pleading.

A stranger auction purchaser acquiring property in a court sale that has not been set aside is protected and may rely on the decree and sale order; the validity of the auction cannot be reopened by collateral examination of prior title disputes. The alternative claim of title by prescription failed because it was not specifically and properly pleaded with the necessary factual foundation, and reliance on Article 526 of the Portuguese Civil Code was not raised as a distinct basis in the courts below. The purchasers' title through the auction was upheld, while the prescriptive title plea was rejected, and the suit was decreed.

Issues: (i) Whether the appellants acquired valid title through the court auction and were entitled to protection as stranger auction purchasers; (ii) Whether the appellants established title by prescription based on long possession and registration under the Portuguese Civil Code.

Issue (i): Whether the appellants acquired valid title through the court auction and were entitled to protection as stranger auction purchasers.

Analysis: The court auction was held under the then applicable Portuguese procedural law, which required publicity through proclamations and notices. In the absence of any challenge to the auction itself and in the presence of the legal protection accorded to a stranger auction purchaser, the purchaser was entitled to rely on the decree and the sale order. The validity of the auction could not be reopened merely by examining antecedent title disputes between third parties, particularly when the auction had not been set aside and the appellants had purchased in execution as strangers to the proceedings.

Conclusion: The appellants' title derived from the court auction was upheld and the issue was decided in favour of the appellants.

Issue (ii): Whether the appellants established title by prescription based on long possession and registration under the Portuguese Civil Code.

Analysis: The plea of prescription was not properly and specifically pleaded with necessary particulars, and the later reliance on Article 526 of the Portuguese Civil Code was not raised in the courts below as a distinct legal foundation. The court held that prescription is not a pure question of law and requires a properly pleaded factual basis. The claim based on prescriptive possession was therefore not made out on the record.

Conclusion: The plea of title by prescription was rejected and this issue was decided against the appellants.

Final Conclusion: The appellants succeeded on their title based on the court auction, while their alternative plea of prescription failed. The decrees of the courts below were set aside and the suit was decreed.

Ratio Decidendi: A stranger auction purchaser who buys property in a court sale not set aside in appropriate proceedings acquires a protected title and cannot be defeated by reopening antecedent title disputes; a claim of prescriptive title must be specifically pleaded and supported by a factual foundation.
