Corruption is of significant concern in Kosovo for its citizens, civil society, the government and the international community. Efforts to address corruption have involved strengthening the criminal justice sector where key agencies such as the police, prosecutors, courts, Anti-Corruption Agency (ACA), tax, customs and procurement authorities and civil society, are expected to collaborate: actively share information and work together throughout the prosecution process. Currently, they do not do this sufficiently well – and few corruption cases are resolved. This brief assesses the main challenges in interagency collaboration and suggests remedies for improving existing coordination mechanisms, reviewing the mandate of the ACA and ensuring collaboration is instilled as a matter of routine.
