The author deals with the possibility of cumulative performance of non-custodial and custodial protective measures adjudicated in separate cases concerning various prohibited acts committed by the same perpetrator. The regulation does not allow the cumulative imposing of measures from Article 93a § 1 points 1-3 of the Penal Code and measures from Article 93a § 1 point 4 of the Penal Code. It should also apply to their performance. Imposing psychiatric detention in one case necessitates performing non-custodial measures in other proceedings. It should entail revoking non-custodial measures (Article 93b § 2 of the Penal Code). In this regard, discontinuing or suspending the enforcement proceeding would be insufficient (art. 15 § 2 of the Executive Penal Code).
