A person shall be criminally liable only upon having acted intentionally, save where he has acted negligently in the event that the law requires him to be liable upon having acted negligently or save where the law expressly requires him to be liable even for having acted unintentionally.

To act intentionally is to act whilst being aware of the act and, at the same time, desiring the outcome or being able to foresee the outcome of such act.

If the offender has no knowledge of the fact which is an element of the offence, it shall not be deemed that the offender desires the outcome or is able to foresee the outcome of his act.

To act negligently is to commit an offence not in an intentional manner but without the care which a person in such a state must have according to his nature and circumstances, and which the offender might have been able to exercise but did not sufficiently exercise.
