The legislation of the past few years brought many changes regarding the criminal law of the juvenile delinquency. The aim was to bring the justice system closer to the people concerned, to make the procedures more cost-effective and to accelerate them. Furthermore, to get the caseload distribution more balanced.

My main intention was to present the operative and relevant criminal law as reflected in the practice of the courts in this article.
