Key legal question
Whether the public law appeal was admissible despite the pending cantonal cassation proceedings.
Extracted holding
The appeal was inadmissible because the cantonal remedies had not been exhausted.
Extracted reasoning
The cantonal court had not yet ruled on its competence and the long inactivity did not justify bypassing it; in these circumstances, the Supreme Court required exhaustion of the cantonal instance, especially since the matter involved a restriction of personal liberty and the cantonal review could offer broader legal protection.
