ON CRIME
CHAPTER I
GENERAL ASSUMPTIONS
Article 11. Commission by action and omission
1. Whenever a legal definition of a crime includes a certain result, the act comprises not only the specific action required to produce it, but the omission of any specific action that would avoid it as well, unless when intention of the law is otherwise.
2. A result caused by omission is only punishable when the perpetrator thereof is under a legal duty that personally obliges the perpetrator to avoid said result.
3. In the case described above, punishment may be extraordinarily mitigated.
