Its "corporal injury on a spouse,"
SO I googled and this was the definition:
Corporal injury to spouse or cohabitant charges are covered under California Penal Code Section 273.5.
It's generally defined as willfully inflicting a physical injury resulting in a traumatic condition on an intimate partner.
Typically, the injuries are visible, but could also include internal injuries.
Some common examples of injuries that would be considered a corporal injury would include:
scratches
bruising
swelling
broken nose
concussion.
A traumatic condition means a wound or other types of bodily injuries that were caused by a direct application of physical force. It's important to note here that the injuries don't have to be a serious physical condition.
A minor wound or injury could be sufficient to be charged with this domestic violence related offense.
