1. That which incapacitated the offended party for labor from 1-9 days or
   required medical attendance during the same period.
2. That which did not prevent the offended party from engaging in his
   habitual work or which did not require medical attendance (Ex. blackeye).
3. Ill-treatment of another by deed w/o causing any injury.
   (Ex. slapping but w/o causing dishonor)

When there is no evidence of actual injury Supervening event converting
crime into serious physical injuries after filing of information can still
be the subject of a new charge

This involves even ill-treatment where there is no sign of injury requiring
medical treatment.

Slapping the offended party is a form of ill-treatment which is a form of
slight physical injuries.

But if the slapping is done to cast dishonor upon the person slapped, or
to humiliate or embarrass the offended party out of a quarrel or
anger, the crime is slander by deed.

Between slight physical injuries and less serious physical injuries, not
only the healing duration of the injury will be considered but also the
medical attendance required to treat the injury. So the healing duration
may be one to nine days, but if the medical treatment continues beyond
nine days, the physical injuries would already qualify as less serious
physical injuries. The medical treatment may have lasted for nine days,
but if the offended party is still incapacitated for labor beyond nine
days, the physical injuries are already considered less serious physical

Where there is no evidence of actual injury, it is only slight physical
injuries. In the absence of proof as to the period of the offended party’s
incapacity for labor or of the required medical attendance, the crime
committed is slight physical injuries.
