Whether the criminal complaint for insult and threats was filed within the three-month limitation period under Art. 31 CP.
No. The complained-of acts occurred in November 2009, while the complaint was filed on 2010-05-11, so the three-month period was not respected.
Insult and threats are prosecuted only upon complaint. The right to complain expires after three months from knowledge of the offence and its author; the delay led to forfeiture of the criminal prosecution.
