Definition and Nature

Quasi-crimes or quasi-offenses are a category of criminal acts primarily linked to criminal negligence and imprudence. Under Article 365 of the Revised Penal Code, criminal negligence is treated as a mere quasi-offense. These acts result from fault or culpa, which involves imprudence, negligence, lack of foresight, or lack of skill.

Distinction from Intentional Crimes

Quasi-crimes, committed by means of culpa, are distinct from intentional felonies committed with dolo. Felonies committed by dolo involve deliberate intent or malice.

Treatment Under the Revised Penal Code

Quasi-offenses are treated differently than intentional felonies under the Revised Penal Code. For instance, Article 48 of the RPC, which addresses complex crimes, does not apply to quasi-offenses under Article 365. Similarly, the rules for applying modifying circumstances found in Article 64 of the RPC are not applied to quasi-offenses under Article 365. Prosecution for a quasi-offense under Article 365 should proceed under a single charge, irrespective of the number or severity of the resulting consequences.
