Art. 22
1 If, having embarked on committing a felony or misdemeanour, the offender does not complete the criminal act or if the result required to complete the act is not or cannot be achieved, the court may reduce the penalty.
2 If the offender fails to recognise through a serious lack of judgement that the act cannot under any circumstances be completed due to the nature of the objective or the means used to achieve it, no penalty is imposed.
Art. 23
1 If the person concerned of his own accord does not complete the criminal act or if he assists in preventing the completion of the act, the court may reduce the sentence or waive any penalty.
2 If two or more persons carry out or participate in a criminal act, the court may reduce the sentence or waive any penalty in respect of any person concerned who, of his own accord, assists in preventing the completion of the act.
3 The court may also reduce the sentence or waive any penalty in respect of a person who withdraws from carrying out or participating in a criminal act if the withdrawal of the person concerned would have prevented the completion of the act had it not remained uncompleted for other reasons.
4 If one or more of the persons carrying out or participating in a criminal act makes a serious effort to prevent the completion of the act, the court may reduce the sentence or waive any penalty if an offence is committed irrespective of the efforts of that person or persons.
Art. 24
1 Any person who has wilfully incited another to commit a felony or a misdemeanour, provided the offence is committed, incurs the same penalty as applies to the person who has committed the offence.
