Key legal question
Whether the refusal to hear C. violated the appellant's right to be heard
Extracted holding
No. The cantonal court could refuse the witness because the proposed evidence was not decisive for the detention review and the file was sufficient.
Extracted reasoning
In pretrial detention, evidence-taking on the merits should not be conducted. The anticipated assessment of the relevance of the requested testimony was not arbitrary, and the appellant's right to be heard under Art. 29(2) Cst. was respected.
