Requirements for Co-Perpetration in Leiden
Co-perpetration is a form of criminal principal liability where two or more persons jointly commit a crime. The requirements for co-perpetration are strict and based on Article 47 of the Criminal Code (Sr). Each co-perpetrator can be held fully principally liable for the entire offense. For Leiden residents, this article outlines the legal conditions, with a focus on practices at the District Court of Leiden, including examples and tips for local support.
Legal Basis of Co-Perpetration
Article 47(1) Sr forms the core: "Those who co-perpetrate a crime are punishable as perpetrators." This distinguishes it from complicity (paragraph 2) and assistance (paragraph 3). Supreme Court rulings, such as the Hofman case (Supreme Court 9 May 1989, NJ 1989/593), clarify the requirements: a factual and psychological unity among multiple persons, with mutual coordination and role reinforcement. The District Court of Leiden applies these criteria rigorously in local cases.
Core Requirements for Co-Perpetration
Three essential conditions must be met, divided into objective and subjective aspects.
Objective Requirements
- Unity of plurality: The actions of those involved form one coherent crime through joint execution.
- Mutual coordination and reinforcement: Roles complement each other, such that the offense would not succeed without collaboration.
Subjective Requirements
- Mutual awareness: Each party knows the other's contribution and approves of the crime.
- Full intent: Conscious will to commit the offense, with knowledge of all relevant facts.
Judges at the District Court of Leiden consider evidence such as messages or joint presence.
Practical Examples of Co-Perpetration in a Leiden Context
Example: Two men rob a jeweler on Breestraat in Leiden. One points a firearm at the owner (principal act), the other uses pepper spray and empties the safe (supporting role). Their coordinated roles qualify as co-perpetration; both face trial at the District Court of Leiden with equal sentencing risk.
Counterexample: A third person waits with the getaway car at Leiden Central Station, unaware of the violence. This lacks the co-perpetration requirements and falls under complicity.
In a Leiden drug case, A ships packages while B handles distribution in Leiden-Noord. Phone coordination and role awareness enable co-perpetration.
Co-Perpetration versus Complicity
Key differences:
| Aspect | Co-Perpetration (art. 47(1) Sr) | Complicity (art. 47(2) Sr) |
|---|---|---|
| Requirements | Joint execution with coordination | Intentional assistance without direct role |
| Liability | Full principal liability | Capped at principal's sentence |
| Example | Two robbers in Leiden | Neighborhood tipster |
| Penalties | Maximum sentence | Up to 7 years lower (art. 57 Sr) |

Frequently Asked Questions on Co-Perpetration Requirements
What if the role is limited?
Even a minor contribution counts if coordinated. Sentence mitigation possible (art. 57 Sr), but principal liability remains.
Must roles be identical?
No, primary or instrumental roles are fine, as long as intent is equal. See Supreme Court De Jong (2002).
Does this apply to family in Leiden?
Yes, family ties are irrelevant. E.g., parents inciting child to theft (Supreme Court 2015).
Insufficient evidence?
Public Prosecution Service must prove the charge; doubt leads to acquittal (in dubio pro reo).
