Capax doli – This legal term comes from Latin. Within the Criminal Law the term defines the ability for performance of a crime and to be responsible for the performed illegal actions. Different legal systems set up different rules describing the capacity for performance of crime and respectively to fall under criminal liability following the provisions of the local Criminal/Penalty Code. Usually these requirements include minimum age of 18 and full mental capability. If the convicted person does not meet these criteria, they cannot be punished with the standard punishment given by the Criminal Law, and usually different measurements or preservations apply to them. For example, if a twelve-year old teenager commits a crime, they should not be punished with a jail sentence, but other measurements should be taken in such case.

The origin of the term is the word “capax”, which literally means large enough, capacious or competent.
