J. Artie Vergel de Dios v. Court of Appeals

Summary

This case involves both procedural and substantive law issues. Procedurally, the Supreme Court ruled that service of an amended complaint directly on a defendant is proper under Rule 13, Sec. 2 when no counsel has yet appeared, and that no new summons is required when the amendment does not introduce a new cause of action but merely supplements existing allegations. The Court upheld the trial court's declaration of default against De Dios for his negligence in not timely filing an answer despite receiving the amended complaint. Substantively, the Court affirmed the rescission of a property assignment contract under Civil Code Art. 1191, finding that De Dios's failure to execute the required deed of assignment constituted substantial breach warranting rescission. The decision emphasizes that procedural rules exist to ensure orderly administration of justice and should not be used to frustrate substantive rights through technicalities.
