Key legal question
Whether the conviction for repeatedly violating the duty to identify the driver under the cantonal traffic levy law was unlawful because of the privilege against self-incrimination or witness-refusal rights.
Extracted holding
The conviction was upheld. After the acquittal on the traffic-rule charges had become final, the appellant could still comply with the disclosure duty without risking self-incrimination for those charges; no other justification for silence was shown.
Extracted reasoning
The witness-refusal privilege was irrelevant because he was never questioned as a witness. The right to remain silent as an accused no longer protected him once the acquittal on the underlying traffic offenses was final, and the duty to disclose continued to apply.
