For a criminal offence committed in a form of omission, someone is accountable, if a special kind of link exists between a perpetrator and a victim, based on which a perpetrator has special responsibilities towards a victim. These responsibilities are those of safeguarding and monitoring.
A criminal offence may be committed by omission only when the perpetrator has failed to perform the act, which he was obliged to perform. The perpetrator shall be guilty if he has committed a criminal offence with intent or by negligence and when he must have or could have been aware that his conduct was unlawful. The guilt of a perpetrator may be excluded if he was in error regarding the circumstances (mistake of fact) or was not aware of a statutory element of such an offence (mistake of law).
Slovenian penal code, unlike some other penal codes (e.g. German) does not allow general grading of the sentence for criminal offences committed in a form of omission, based on mitigating circumstances. But in theory, an optional grading of the sentence would be justifiable in cases when mitigating factors are presented.
