Theory of crime · Articles 27-31 CP · Throughout Spain

Principals and participation

Being present is not being guilty to the same degree: principal, accessory or bystander, the distinction is worth years.

Who answers for the offence, and in what capacity? Articles 27 to 31 of the Spanish Criminal Code distinguish the principal, the co-principal, the indirect principal, the inducer, the necessary cooperator and the mere accessory. The exact role determines the sentence — and is often the heart of the defence.

In brief. Articles 27-31 CP distinguish principals (Art. 28: direct principal, co-principal, indirect principal, inducer and necessary cooperator) from mere accessories (Art. 29), who receive a sentence one degree lower. Article 31 governs acting on behalf of another. The exact qualification of each person’s role is decisive for the sentence.

Each answers for their role

The law grades liability by contribution. The principal carries out the act; the necessary cooperator makes an indispensable contribution; the accessory provides secondary help. This gradation directly commands the sentence.

The line is often thin. Distinguishing the necessary cooperator (punished as a principal) from the mere accessory (one degree lower) is a recurring question of fact and law, decisive for the outcome.

Inducement and acting for another have their own regime. The inducer who directly determines another answers as a principal (Art. 28); Article 31 attributes the act to the person acting as director or representative of a legal entity.

Our difference

Accessory or cooperator: one degree, several years

The qualification of the role is a major issue. Requalifying a necessary cooperator as a mere accessory lowers the sentence by one degree; establishing mere passive presence may exclude any liability.

We analyse each person’s real contribution. Whether the help was indispensable or secondary, whether a common plan existed or control of the act was absent determines the capacity — and the sentence — of the accused.

FAQ

What you should know

What is the difference between a principal and an accessory?
The principal carries out or controls the act; the accessory provides secondary, non-indispensable help and receives a sentence one degree lower (Art. 29).
What is a necessary cooperator?
Someone whose contribution is indispensable to the commission of the act (Art. 28 b); they are punished as a principal, hence the importance of requalifying them as an accessory.
Is the inducer a principal?
Yes. Someone who directly determines another to commit the offence answers as a principal (Art. 28 a), to be distinguished from mere influence.
Is mere presence enough to convict?
No. Passive presence, without contribution or agreement, does not ground punishable participation; it is a frequent line of defence.
Does the director answer for the company’s acts?
They may, under Article 31, and the company itself under Article 31 bis, under distinct regimes.
How is the qualification of the role contested?
By analysing the real contribution of each person. The firm assists 24/7 in Spain.
