Questão jurídica principal
Whether statements made at the first interrogation were unusable because mandatory defense had already arisen
Decisão extraída
Yes. The first interrogation occurred after a case of mandatory defense had arisen, so the uncounseled incriminating statements were not usable against the defendant under the applicable cantonal practice.
Fundamentação extraída
Mandatory defense existed already at arrest, given the suspected murder and the defendant's own admission. Under Zurich practice, the decisive point is when mandatory defense arises, not when counsel is actually appointed or the accused waives counsel.
