Questione giuridica chiave
Whether arrested suspects must be informed of the right to remain silent under Art. 31(2) BV and whether the failure invalidates their statements.
Decisione estratta
Yes. The duty to inform arises directly from Art. 31(2) BV, and statements made without that warning are in principle inadmissible unless an exception applies.
Motivazione estratta
Art. 31(2) BV protects persons deprived of liberty by requiring immediate information about their rights. The right to silence is one of those rights. Because the accused was not warned and no exception was shown, the police and district authority breached the constitutional duty.
