Here are selected June 2009 Philippine Supreme Court decisions on civil and related laws:
Contract; novation. Article 1292 of the Civil Code provides that “[i]n order that an obligation may be extinguished by another which substitutes the same, it is imperative that it be so declared in unequivocal terms, or that the old and the new obligations be on every point incompatible with each other.” Novation is never presumed. Parties to a contract must expressly agree that they are abrogating their old contract in favor of a new one. In the absence of an express agreement, novation takes place only when the old and the new obligations are incompatible on every point. The test of incompatibility is whether or not the two obligations can stand together, each one having its independent existence. If they cannot, they are incompatible and the latter obligation novates the first.
