Key legal question
Whether the youth proceedings could be applied to a municipal offence under Zurich law
Extracted holding
Yes. Although the federal youth procedure does not itself cover cantonal or municipal petty offences, Zurich had declared it applicable to such offences by cantonal statute.
Extracted reasoning
The cantonal provision extended the JStPO to cantonal criminal law and municipal petty-offence law, so the youth authorities were competent.
