Spouses Federico Franco v. Intermediate Appellate Court

Summary

This Supreme Court case established the crucial distinction between employer's subsidiary liability under the Revised Penal Code versus primary liability under Civil Code quasi-delict provisions. Following a 1974 vehicular collision that killed both drivers and passengers, families sued the bus company owners. Lower courts incorrectly applied criminal law subsidiary liability provisions. The Supreme Court clarified that without criminal conviction of the employee, employer liability must be based on Civil Code Articles 2176 and 2180 (quasi-delict), making the employer primarily liable subject to due diligence defense. The Court also ruled that appellate courts cannot increase damage awards when successful parties didn't appeal. This decision significantly clarified Philippine tort law regarding employer liability for employee negligence in civil contexts.
