Key legal question
Whether the constitutional complaint could challenge the lower cantonal decisions directly rather than only the cantonal appellate judgment.
Extracted holding
Only the cantonal appellate judgment was the proper object of the constitutional complaint; attacks on lower-instance decisions were inadmissible.
Extracted reasoning
The conditions for the 'Dorénaz' exception were not met because under cantonal procedure all defects could be raised on appeal, so the last cantonal instance had full review power.
