Negligence

A negligent offence requires three elements:

The duty of care has two dimensions: an internal duty to perceive danger, and an external duty to act accordingly.

Spain uses a numerus clausus system. Under Article 12 of the Code, negligent acts are punished only when expressly stated by law.

The Code distinguishes between degrees of fault:

Professional negligence breaches calling-specific duties and adds disqualification penalties.

Preterintentionality means intending a lesser harm but causing a greater one. We treat this through concurrence rules: intent for the base act, negligence for the outcome.

Omission

Pure omissionCommission by omission
StructureFailing to actFailing to prevent a result
Result requiredNoYes
PerpetratorAnyoneGuarantor only
ExampleFailure to render assistanceHomicide via Article 11

Under Article 11 CP, omission must be equivalent to active causation. It requires a breach of a special legal duty based on:

Causation here is strictly hypothetical. We ask if the omitted action would have avoided the result with near certainty.

Common pitfall: assuming that ease of prevention creates guarantor status. Without a specific legal duty, failing to intervene is only pure omission, not homicide.
