The Principle of Ne Bis in Idem in Leiden
The principle of ne bis in idem, enshrined in Article 68 of the Dutch Criminal Code (Sr), prohibits the prosecution or punishment of an individual more than once for the same act following a final decision. In Leiden, where the District Court of The Hague (Leiden branch) handles numerous criminal cases, this principle ensures legal certainty and protects individuals from repeated legal proceedings along the Leiden canals.
It applies both after conviction and acquittal by the Leiden court. A final acquittal from the Leiden District Court bars prosecution for identical facts; in the case of a conviction, no new penalty may be imposed for the same offence unless the facts differ, such as in local incidents around the university.
Exceptions and Delimitations in Leiden Practice
Exceptions exist, such as in cases of continued conduct or new legal qualifications. The Supreme Court of the Netherlands applies a factual and circumstantial test: identical facts block reopening. In Leiden, this often arises in complex cases, such as fraud in the medical sector around LUMC or violent offences during events like the Leiden Marathon. This prevents abuse while allowing for prosecution of new offences.
The European Court of Human Rights (ECtHR) oversees the application of this principle through Article 4 of Protocol 7 to the ECHR, which is relevant for cross-border cases originating in Leiden.
Practical Implications for Leiden
Violation of this principle may result in a declaration of inadmissibility of prosecution at the District Court of The Hague in Leiden. For defendants, it provides legal certainty following cases handled by the Leiden Public Prosecution Service; for the Public Prosecution Service, it necessitates careful case preparation. Finality activates this protective shield effectively in local jurisprudence.
