AGUIRRE V. PHENG
18 SCRA 18
Aldabas sold to Aguirre a steel tank but the latter wasn't able to take possession. Then the steel tank was sold by Aguirre to Gabriel who subsequently sold it to Leonora and Company and eventually was sold to NASSO. Aguirre notified NASSO of its claim of ownership and thus, it withheld payment to Leonora. In both actions, Aguirre was held to be the owner and entitled to P900.
There is accession by specification. Aguirre should reimburse Leonora for being a builder in good faith.
