Key legal question
Whether the cantonal detention-extension order was sufficiently reasoned under the right to be heard and Federal Supreme Court reasoning requirements.
Extracted holding
No. The order failed to address proportionality and therefore did not meet constitutional and statutory reasoning requirements.
Extracted reasoning
Proportionality is a fundamental factor in a serious deprivation of liberty. Neither the detention order nor the investigation judge's reasons mentioned it, so judicial review was impossible without examining the file.
