G.R. No. 3783 - Santiago vs. Insular Government

On May 2, 1906, the plaintiffs filed a petition in the Court of Land Registration seeking to register under the Torrens system, in accordance with the laws of the Philippine Islands, a parcel of land.
The property was described as "A fish pond or breeding ground" located in the district of Dampalit, municipality of Malabon, Rizal Province, P. I. It was bounded on the north, east, and south by the lands of Miguel Pascual, and on the west by the fish ponds of Servillano Santiago.
The land measured 20 ares, 18 centares, and 68 thousandths. Additionally, it had been last assessed for land tax purposes at $97 (for the land) and $30 (for the buildings).

The Insular Government opposed the petition by arguing that the lands in question were not agricultural; rather, they were classified as "viveros de peces" (fish ponds).
Based on this classification, the government contended that the plaintiffs were not entitled to have the property registered under the Torrens system as provided by Act No. 926 of the Philippine Commission.

After the presentation of evidence and the hearing of arguments from both parties, the lower court issued a decision ordering the registration of the disputed lands.
The court directed the issuance of a certificate of registration to the plaintiff, confirming the registration under the applicable laws.

Following the lower court's decision, the defendant (the Insular Government) appealed the ruling.
In its appellate brief, the defendant maintained that the same questions of law and fact were raised in the earlier case of Mapa vs. The Insular Government (Cause No. 3793, 10 Phil. Rep., 175).
In the Mapa case, this court had previously held that lands of the nature described in the present petition are to be considered agricultural lands and are thus registrable under Act No. 926.

Whether the lands described as a fish pond or breeding ground fall within the definition of "agricultural lands" under Act No. 926.
Whether the classification as agricultural lands qualifies the property for registration under the Torrens system.

Whether the argument that the property being a fish pond (or vivero de peces) categorically excludes it from being considered agricultural is legally sustainable.

Whether the doctrine and conclusion established in Mapa vs. The Insular Government are applicable and controlling in the present case.
