Theory of crime · Article 11 CP · Throughout Spain

Omission and commission by omission

Failing to act can bind as much as acting — but only for those with a duty to act.

Spanish criminal law also punishes failing to act: pure omission (failing to rescue, failing to prevent an offence) and commission by omission (Art. 11), which equates to action the failure of a person in a position of guarantor who lets a result occur that they were bound to prevent.

In brief. Article 11 CP governs commission by omission: the result is attributed to a person under a legal duty to act (position of guarantor) who fails to prevent it, where the omission is equivalent to action. Alongside, pure omission — failure to rescue (Art. 195) or to prevent certain offences (Art. 450) — punishes the inaction itself. The position of guarantor is the central issue.

The weight of inaction

Not all inaction is punishable. Commission by omission (Art. 11) requires a specific legal duty to prevent the result — the position of guarantor — and an equivalence between the failure to prevent it and its active causation.

The position of guarantor has precise sources. It arises from a legal or contractual obligation, or from the perpetrator’s prior creation of a risk (interference). Outside these sources, there is no commission by omission.

Pure omission stands alone. Failure to rescue (Art. 195) or to prevent certain offences (Art. 450) punishes inaction regardless of any result, provided intervention was possible without risk to oneself.

Indicative elements based on the Spanish Criminal Code. Liability depends on the existence of a duty to act and the equivalence of the omission to action. This overview does not replace a lawyer’s analysis.

Our difference

No position of guarantor, no commission by omission

The position of guarantor is the key to the case. Establishing — or refuting — a specific legal duty to act determines whether the inaction equates to action and thus grounds liability.

We dispute the duty and the ability to act. The absence of a source for the guarantor duty, the material impossibility of intervening or a risk to the omitter are all arguments to rule out the offence.

FAQ

Yes, in two cases: pure omission (failure to rescue, Art. 195) and commission by omission (Art. 11), which attributes a result to the guarantor who fails to prevent it.
What is the position of guarantor?
A specific legal duty to prevent a result, arising from law, contract or the prior creation of a risk (interference).

Must I prevent an offence?
Article 450 punishes someone who, being able to, fails to prevent certain serious offences against the life, integrity or liberty of persons.
