Choice between administrative and criminal enforcement in Leiden
In Leiden, administrative enforcement (Awb) competes with criminal law (WVW, WvSr). The municipality of Leiden primarily opts for administrative fines for violations such as parking nuisance or environmental incidents around the university campus, but the Public Prosecution Service may take over in serious cases (art. 5:44 Awb). Ne bis in idem (art. 68 Constitution) prevents double punishment of Leiden residents.
The legal qualification differs: the board of mayor and aldermen tests objectively for norm violation, while criminal law requires subjective intent. Administrative fines are efficient for common violations in busy neighborhoods such as the city center or Pieter van Leydenlaan.
Agreements in Leiden policy
The Leiden LAP (Leiden Approach Priorities) coordinates with the LAPD (Guideline Approach Perpetrator Offense). For environmental offenses along the Oude Rijn, priority is given to criminal law in cases of intent. Local judiciary, such as at the subdistrict court in Leiden, harmonizes sanctions with regional frameworks.
This dual-track policy maximizes deterrence in Leiden without overburdening the local BOA's and the Leiden-South police unit.
