Key legal question
Whether the audio-video recording was unlawfully obtained and therefore inadmissible.
Extracted holding
The recording was admissible because X. knowingly and openly spoke and acted in the complainants' apartment, where he had no expectation of secrecy, and effectively consented to the recording.
Extracted reasoning
The protected sphere under Arts. 179bis and 179quater StGB presupposes a secrecy interest. Because the recording was made openly during an escalating confrontation and X. continued his threats despite seeing it, the unlawful character was absent.
